Themes of Biology - The Book That Changed the World

Themes of Biology - The Book That Changed the WorldThemes of Biology is a reference book that was introduced in the 1980s. These days, it has been updated again. It is not known to any other to be updated since it was first introduced.A major theme of Biology has been how it has changed the world. The book not only reflects the life of man but also points out some special aspects of human beings. The perspectives of this book are wide ranging. They cover a wide array of things, including biology, evolution, human behavior, natural environment, and sociology.Diversity is one of the major themes of this book. It discusses what diversity means and how humans are able to deal with diversity.Ecological Diversity is another theme. It describes how humans have been able to deal with this problem as well as being able to survive during some times of ecological stress. Examples are the Great Pleistocene extinction, low-level biotic crises, and the effects of human-induced environmental stress .Relatedness is yet another important theme. This helps you understand the impact of relatedness in the various environments of life. It includes analysis of three basic questions: when, where, and why?Themes of Biology is a very interesting book. I actually bought it first time because I read it a long time ago and thought it was really interesting. I would recommend it to anyone who loves biology. For someone like me, I can say that there is an infinite number of topics to cover in this book.It is always a better option to buy the book from the bookstore where you can compare the price with the other one. Prices vary with each store. Also, ifthe book does not seem to be relevant to your needs, then it is better to shop around from other stores.

Tips to Improve Your MBA Candidacy Starting Today

Tips to Improve Your MBA Candidacy Starting Today GMAT MBA Admissions Blog If an MBA is in your future, it is never too early to start improving your profile. MBA applications require a significant time commitment, with applicants devoting hundreds of hours across months to prepare their applications. Starting well ahead of deadlines will help you to manage your time and to make sure that you are able to give your applications your best effort. Whether you plan to submit an application this year or in the next few years, you can take steps today to improve your chances at getting into your top MBA program. Add volunteer and leadership experience. For the application process, is important to show that you have interests outside of the workplace and that you take an active role in those activities. Attending business school is a social experience and it is expected that you will take part in many different types of activities to build bonds with your cohort. Admissions committees want to see that you are an active participant with extracurricular activities and that you will be an engaged member outside of the classroom. Now is not the time to pick up a new activity for the sake of the application. Instead, consider your hobbies and the activities that you have been involved with in the past and if there are opportunities for you to strengthen your involvement. Leadership experience is an important part of the application; however, many MBA applicants work in competitive jobs and do not have a lot of down time. Nevertheless, you should try to find opportunities to take on leadership roles. These roles can be with an internal organization at work or with an extracurricular. Demonstrate initiative where you can, it will help you to stand out on your applications. Interact with your target business schools. Getting an MBA ensures that you will become part of a business network for life. Networking is so important in the business world; yet, many people forget about the importance of networking during the application stage. There is a lot of information related to MBA programs: rankings, the programs’ websites, blogs, and videos. Admissions committees want to see that you have gone a step beyond the information that is online and that you have directly interacted with business schools. This indicates your interest in the program and also sets you apart from other applicants who have not done an in-depth level of research. In-person connections are also valuable for you. They will allow you to confirm that the program is a good fit. Take time to visit business schools if they are located nearby or if you can travel. If you do visit, meet admissions staff, go on a campus tour, and attend a class. If you are not able to visit a school, then attend virtual events. Many schools offer informative webinars or other virtual ways to interact with them. Reach out to students. Speaking with current or recently graduated MBA students is a great way to learn more about the culture of the program. They will be able to share an insider’s perspective and will provide more nuanced information than you would get from reading a website. Take or retake the GMAT. While some people are natural standardized test takers, the GMAT is a hurdle for most in the MBA application process. Your GMAT score is valid for 5 years so why not study for and take the exam early? Once you begin the application process, you will become occupied with the other aspects of the application. Preparing for and taking the exam at a strategic time, when you are less busy, will minimize the stress of the process. Taking the GMAT at least twice is also a good idea. Ideally you want to have a GMAT score that is on par with or higher than the average score at your target schools. If on your first attempt, you earn a score that is the average score of your target schools, consider taking the GMAT once more to see if you can get a higher score. The admissions committees also want to see that you have self-awareness about your statistics and that you are trying to elevate your candidacy to the very best that it can be. Choose your recommenders. Letter of recommendations are the wildcard of the application. Many applicants have a recommender who agrees to help them only to delay submitting the letter or to back out at the last minute due to other obligations. You will spend a lot of time and effort on your application so do not leave this portion to chance. You should be prepared to guide your recommenders by providing examples and anecdotes that showcase your strengths. You can start to keep track of these interactions so that you will have notes ready for the letters. Make sure that your recommenders have more than enough time to complete their letter and that they know what to expect. It is also good practice to have a backup candidate in mind in case your recommenders are not able to fulfill their obligation.

Plus, you can record yourself speaking to check your pronunciation.Hello-Hello offers 13 languages, which largely overlap with Babbels offer ings.While the app download is free, you must purchase a license to use the app. However, since this is a one-time fee, if youre planning on using the app for a long time, it may be more affordable than Babbel.FluentUFluentU also focuses on conversational language and realistic examples, but as an added bonus, it does so through revamped online videosâ€"the same stuff native speakers watch. How cool is that? FluentU takes real-world videosâ€"like movie trailers, music videos, news and inspiring talksâ€"and turns them into personalized language lessons.With FluentU, you can see a word or phrase in multiple contexts, including example sentences and different video clips pulled from across the site. Each video comes with interactive captions, and its easy to automatically pause a video and dig into definitions, images and usage.The quizzes, which can correspond to videos but also be synced with customized flashcard sets, allow you to personalize your learning, not that your learning is nt already personalized, anywayâ€"FluentU keeps track of all the words youve learned, and you can mark off the words you already know, so you never waste time studying material youve already learned.Like Babbel, FluentU is highly convenient, as you can use it between multiple devices (Android, iOS and/or web) and squeeze in small amounts of practice here and there.

FluentU is currently available for 9 languages and counting.DuolingoAvailable: iOS | AndroidDuolingo has a lot of features that are similar to Babbel, and guess what? You dont have to pay for Duolingo unless you want to unlock special material.One way Duolingo is like Babbel and FluentU is that it offers flexible time commitment. However, while Babbel gives you 10-15 minute blocks, Duolingo lessons usually only take around 5 minutes, so Duolingo may be perfect if you dont have the time to commit to Babbel. But like Babbel and FluentU, you can also use Duolingo for longer stretches of time whenever you want.Duolingo also gives you speaking practice. You can record words and phrases and compare them against the audio example. However, if you dont want to speak at the moment, you can also opt out of this option.Duolingo uses plenty of example sentences to help you learn words in context.

However, if full conversations arent your thing, Duolingo may be an ideal alternative to Babbel.Mango LanguagesAvailable: iOS | AndroidMango Languages has a lot of the features Babbel users love.For instance, this program also uses realistic example conversations to teach vocabulary and give learners conversational skills.And the Mango Languages recording feature allows you to record your own pronunciation and compare it head-to-head against a native speakers pronunciation, giving you the opportunity to perfect your accent.Plus, with over 70 language options, youll have way more languages to choose from than Babbel offers. So if Babbel doesnt offer the language you want to learn, Mango may be the course to check out.While theres a free trial, a subscription is required for additional lessons.HelloTalkAvailable: iOS | AndroidIf your favorite Babbel feature is the conversation-based learning, HelloTalk could take your language skills to the next level.Thats because HelloTalk is also conversation-based. However, rather t han simulating realistic conversations, HelloTalk provides you with real conversations with native speakers, allowing you to learn vocabulary in a completely authentic context. And since the app offers translations and corrections, your language skills dont even have to be close to perfect to start using HelloTalk today.And,  HelloTalk supports over 150 languages. Good luck finding a language you cant practice through HelloTalk!The basic service is free, though additional purchase options can allow you to learn more languages, search based on more traits and unlock more translation tools.Bliu BliuBliu Bliu is a website-based learning option that offers some Babbel-esque features, like a low time commitment and the intention of helping you learn faster.Bliu Bliu suggests you study for just 10 minutes a day, similar to Babbels recommendation.

GCSE Grading Changes - Tutor Hunt Blog

GCSE Grading Changes GCSE Grading Changes GCSE Grading ChangesSecondary SchoolsThe GCSE qualification is about to undergo a huge change as of August 2017. The changes relate to a new grading system as well as alteration to the syllabus.A numerical scoring system will be replacing the current A* - G system. The only remnant of the old grading method will be the U - unclassified - ; for those pupils who fail to achieve the minimum mark.A grade of 9 will be the highest achievable ranking, replacing the A* - while a grade 1 will be the lowest. A grade 5 will be classed as a good pass - perhaps the equivalent of a B or C grade. Pupils should be aiming for a ; grade 5 or higher. With a C grade being the minimum pass grade in the current system, some have said that the new numerical system will make it slightly harder to achieve a pass grade, since they must now aim for a B - C grade. This new nomenclature has been designed to heighten the differences at the top end of the academic spectrum - with the A and A* being differentiated more sharply. Infant people are already saying that a grade 9 will be the equivalent of an A**, and will only be awarded to the cream of the crop - the top 3% of pupils.The demand of the content is increasing, with tougher topics being introduced for both foundation and higer papers. In Mathematics there will be a greater emphasis on problem solving and mathematical reasoning and students will be required to memorise more formulae.GCSE s were introduced back in 1988, when they replaced O-Levels and the CSE exams. Over the last for years there have been a number of changes to the qualification, one being the removal of GCSE English from the syllabus. This is not quite as radical as it first sounds, since it was replaced by GCSE English literature and GCSE language. The language qualification, along with Mathematics, is a mandatory qualification - English literature being an optional (though extremely popular) subject.Though the first set of results bearing the new grading system wi ll not be released until August 2017, current year 10 students are already studying for these exams. The new grading system will not cover all subjects however: only results for English Language, English Literature, and Mathematics will be graded from 1 to 9 in the results next August. The remaining subjects will carry the traditional A - G grades. Year nine students are currently studying for the new GCSE grade in most subjects - more eclectic subjects will still be marked according to the old system for this year group. Only from 2018 will the all subjects be graded according to the new system. Along with the different grading system there are a number of accompanying changes - perhaps the most significant (and most publicised) is the removal of assessed coursework from those subjects where large written projects traditionally contributed to the final grade.In English there will be a far greater demand for students to students to read a broader range of literature. In the past the re was criticism that many of the more challenging novels had been excised from the syllabus. Students will be required to study literature from diverse periods. Fifty years ago Chaucer was required reading for most school children; while today anything earlier than the nineteenth century is rarely read and taught in schools.The modular character of certain subjects will be completely dropped. There won't be number of assessments throughout the course, with each one contributing slightly to the student s final grade. Instead there will be a a set of exams at the the end of the two years, with everything resting upon ; how well the students perform in them. The major change will be more demanding and challenging content in all subjects. With too many students achieving As and A*s in recent years, there has been less opportunity for the abilities of high achieving students to be differentiated. Last year 25.8% of students got an an A or A* grade in all subjects; and whil e this may sound impressive, what it also means is that more than a quarter of students can only be ranked into two groups, differentiated by the A and A*. With a more challenging syllabus, and a grading system permitting a finer grading resolution, perhaps our education system will be able to compete with those of Asia and parts of Europe. Given the UKs dismal position in the PISA (Programme for International Student Assessment) rankings over the last decade, a change of some kind is certainly needed. 3 years ago0Add a Comment

What Is a Chemistry Compound Calculator?

What Is a Chemistry Compound Calculator?A good chemistry compound calculator is one of the few tools that you will need to use when you are learning chemistry. These tools are used by most students of chemistry, to help them figure out the different components of different compounds and what the differences in those compounds are.You can find these in various places. If you go to a chemistry classroom, the teachers will probably have them with them; if you choose to buy a chemistry compound calculator for your own personal use, you will find it at almost any electronics store that sells electronic supplies.When you use a compound calculator, you need to know what the constituent parts of the compound are. The name of the compound is usually the first thing that comes up. After that, you are asked to enter the number of carbon atoms that the compound has. Next, you will be asked to enter the amount of hydrogen atoms it has.Once you have entered these values into the compound calculato r, it will display a list of all the components of the compound. It will also give you a detailed explanation of the components. This can make it quite difficult to understand the properties of the compound. For this reason, you will probably want to pay close attention to the results of the compound calculator.You will be able to get a compound calculator for free if you register on a website that offers free chemistry testing. For some reason, companies or businesses don't seem to have many good quality free chemistry compound calculators, so they often charge for the privilege of being able to use one. The free ones are probably not very good, though, since you may need to take a lot of practice tests before you get good enough at the compound calculator to learn about something that you already know a lot about.One other place where you can find a good compound calculator is on a chemistry blog. Formany years, a great number of chemistry bloggers have made these types of calcula tors available to their readers, and now they are available online as well. Some of the sites offer many other features, including a review section where you can read about a particular compound.For anyone interested in learning chemistry, a compound calculator is a must have. If you do not already have one, now is a great time to get one for yourself.

How to Choose your Paint Brushes

How to Choose your Paint Brushes How to Select the Best Paint Brushes for Painting ChaptersThe Anatomy of a Paint BrushPaint Brush BristlesBest Paint Brushes by MediumChoosing Paintbrushes According to TechniqueHow to Clean Paint Brushes?Whether you are a building painter, an artisan painter or a painter of canvases, you may have run into the same dilemma: which is the best brush for your medium?Different media â€" watercolors, acrylics, oils and gouache all require different types of brushes.Furthermore, each style of painting demands its own technique   and specific tools - brushes foremost among them.From wide brush strokes for landscapes and still lifes, to the meticulous dabs required for portraits and otherwise drawing people, each brush is selected based on bristle type, brush tip, and more: the handle, and the weight and size.Information on the Internet and art magazines can be boggling: so many brushes to choose from, with no real guide as to which brush would be best suited to what medium, and hardly no information on how to select proper size or tip.Perh aps these art supply vendors expect everyone to learn these distinctions in art school or drawing class.Maybe you've not attended any drawing tutorials. Maybe you are picking up a brush for the first time because you feel so inspired.If that is your case, Superprof now dons an artist's pinafore and beret to give you step by step instructions about brushes for painting portraits, or any other masterpiece, in all media.Find different drawing lessons online here.delicate areasused to learn how to draw eyes, for example, or adding definition to human face drawings.The detail round is great for short strokes. In learning how to draw hands, you may use such a brush for lines around knuckles, for example.Flat brush is good for bold colour strokes on large canvases, and filling wide spaces.The angular flat brush is good for filling in corners or making curved strokes. They can be used like flat brushes.The bright is a flat brush with short hairs that curve inward at the tip, good for thick, heavy colour applied in short strokes.the Filbert is an oval-shaped brush what works well to blend and shade. If you have just learned how to draw a rose, you may use a filbert to refine your shading technique.The Fan has spread out hairs, good for smoothing, blending and feathering colours.This type of brush gives excellent texturing effect if you are painting clouds, trees or creating a seascape.With all of this variety in painting tools, don't you feel pity for the digital artist who renders art on a virtual canvas with nothing but a drawing tablet?Consider investing in an assortment of brushes suitable for all media Source: Pixabay Credit: WerbelFabrik not for the movement they represent, but for their medium: oil, acrylic and watercolour, respectively.Naturally, the type of brushes they used accorded to their preferred medium.Portraiture in WatercolourTo paint a portrait â€" or anything else with watercolours, you should use a fine brush with a short handle.You may already kno w that from your drawing lessons, but still, you wonder: would a sable brush be called for, or could a squirrel brush suit?Squirrel hairs are very fine, which makes it easy to achieve various effects, using the same brush.With a bit of pressure, you can use the belly of the brush to make a broader stroke. Or, you can back off, using only the tip: a great way to contour or outline.These natural hair brushes are perfect for watercolours because they are very fragile, and should not be cleaned with solvents.Find the best drawing lessons here.Acrylic PaintingBy their very composition, acrylic paints damage natural fibre paint brushes. Therefore, it is best to use synthetic brushes when expressing yourself in this medium.Made of nylon or perlon, they provide a soft yet resistant fibres; a more advanced method to transmit colour to canvas.This type of brush (and the medium itself) makes for good line drawing, and could even substitute for a graphite pencil  or other type of pencil if you are doing any crosshatching or ink drawing.Oil PaintingSo much work goes into preparing both your canvas and your brushes, to work with this medium.Often, the artist must retouch his work in order to create a perfect still life or portrait painting in oil.Purists gravitate toward hog brushes or ox hair, both for economic reasons and because of the finesse they give to the portrait.The filbert stands as the brush of choice for many oil painters.Of course, if you are creating a digital painting to share on  an interactive whiteboard, brushes of any type matter not at all!The Filbert brush is the brush of choice for oil painting Source: Pixabay Credit: NietjuhChoosing Paintbrushes According to TechniqueA rock guitarist may secretly prefer a folk guitar, while a gypsy jazz guitarist would swear on the acoustics of only Gypsy guitars.When choosing art materials, your mind follows the same reasoning: which brush would best match my technique?For subject matter with a lot of detail, if you like to sketch or draw animals and then paint them, for example, you should opt for a short handled brush with soft bristles.If you are in a Drawing for Beginners class, for instance, you may have already experienced the advantages that proximity to your canvas can bring: tighter control of your brush strokes, and more flexibility in your wrist.And why would you want a paint brush with soft bristles? Doesn't that seem like a good way to miss a stroke or make unsightly blotches?Painting with firm bristles does provide the advantage of control.However, you may leave visible brush strokes on your life drawing or even in the shadows you create.You may even scratch your canvas or watercolor paper!If your art drawing has a lot of detail, you should probably choose from the array of synthetic hair brushes to render your work.By contrast, large swaths of uniform color would best be rendered with a long-handled, hard bristle brush.You can get a better perspective on your work by grasping th e brush toward the end of the handle. This permits you a bit of distance, to take in the whole of your art.The art of oil painting demands thick-haired brushes to effectively convey your dense and heavy colour to canvas.For watercolors, you need a softer brush, because the medium itself is very fluid.Acrylic paints are softer than oils but thicker than watercolors, so you have a greater range of firmness to work with.But the brushes you choose should be chemically resistant: hence the earlier recommendation for nylon brushes.The artist who specialises in pencil drawing has the same quandary as you, a painter. S/he must choose pencil and paper carefully, to suit his drawing technique.Check out these drawing lessons for kids!Choosing the Correct Drawing Tools and BrushesYour paintbrush is a magic wand for realising face drawing, perspective drawing... anything you are learning to draw!Of course, we're exaggerating. There are no such things as magic wands.Still, we maintain: those inst ruments used to transfer your vivid imagination into visual art will become an extension of you.Once you've mastered how to express light and shadow, contour drawing... everything beyond stick figures, you will find you can realistically draw something, and then fill in those lines to render your scene almost three dimensional, for a beautiful work of art just ready for framing.It all comes down to using the right brush.Storing your brushes upright when wet could cause them to warp and bend Source: Pixabay Credit: StocksnapHow to Clean Paint Brushes?Unlike the digital drawing artist, who does not need to clean much of anything pertaining to his medium, you must take proper  care of your art materials.Cleaning your brushes, just like an art professional does, will prolong the life and utility of those tools.Once you have framed your canvas, or if you are just done for the day, you must make effort to clean and preserve your equipment.Here are a few tips on how to draw every last bit of paint from your brushes' fibres:Remove as much paint as possible, either by wiping your brush repeatedly (for oils and acrylics), or by running them under water.For watercolours, you can massage the brush head until water runs clean.If the paint has already hardened, work the bristles gentlyWash your brushes in warm, soapy waterWork the brushes gently and carefully.Rinse in cool, clear water, and then pat dry.You should lay  your brushes on a flat surface, in a cool, dry area away from heat.Following these methods, you will be able to pick up those brushes the next day to fill in your sketches, practicing textures and blending shades  anew.
