Over time many theories have been put forward by the scientific community about how the process of evolution occurs. However the most commonly accepted theory amongst scientists is that evolution occurs by the process of natural selection. This was put forward by Charles Darwin. He proposed that:
There is naturally occurring variation in any given population - this is due to the variety in alleles which give rise to a variety of phenotypes (observable characteristics).
Those individuals who are better adapted for their environment as a result of the alleles they posess are more likely to survive and reproduce successfully.
Hence their offspring will inherit these alleles and so will also be more likely than others in the population to survive and reproduce etc due to the inheritance of these advantageous traits.
Over a long period of time as the process of natural selection continues, there is a gradual change in the characteristics of a population by which members become better adapted for the environment in which they live. This is evolution by natural selection.see more
The first and most important thing that you should do before even beginning your essay is to take a moment to do a quick plan.
This should briefly outline the main strcuture of your essay, the key points you want to make, any quotes and themes etc and the order you'd like to set your ideas out in. This should help you to keep your essay focused, enabling you to include all the points that you intend to and will hopefully prevent you from venturing off topic.
Here is an example of how you might set out an essay. Of course everyone has their own style of writing but these are probably the key bases to hit in order to create a strong foundation for any essay:
1. Introduction: This should be concise and focused on the essay question, it should give some context about the text(s) in question, such as a brief description of the setting or an outline of the characters in question, for example. You may also want to briefly state where you are heading in your essay and the main things that will cover. This shouldn't take you long and should only be a few sentences in length.
2. Main Body - Set this out as a series of paragraphs, each following the PEE structure:
Point - state what this parapgraph will demonstrate and be careful not to story tell.
Evidence - the points you are making should always be backed up with evidence from the text. Try to include a fair number but not to the point of overload. If you are making lots of points without evidence or giving lots of quotes without making a point then the examiner may question your understanding of the text, and we don't want that. If you can't remember a quote for every point, then don't worry, you can always brielfy desrcibe the moment instead.
Explanation - After making your point and providing some evidence, you must then explain the effect of the evidence that you have quoted. Try and critically analyse it. These questions may help: What does it show? Does it particularly emphasise something in the scene? Does it emphasise a major theme of the text? What effect does it have on the reader? Are there any literary devices that are being used that may aid the point the author is making?
At the end of each parapgraph, try and remember to link it back to the main essay question. Again this will prevent you from going off topic, keeping your analysis focused and will show the reader that you have really considered the essay question.
3. Conclusion - An essay without a conclusion is like a story without an ending. Like the introduction it needn't be too long and the use of quotes is not generally encouraged. Simply outline the main things you have discussed, drawing back on the key points that you have made in the main body, and then link them back to the overall question. This should show that you have carefully considered the question throughout your essay and have been critical in your analysis. :)see more
Non-disjunction is the failure of chromosome pairs to separate properly during meiosis. This failure of separation usually occurs either in meiosis I (in anaphase I) or in meiosis II (in anaphase II).
The consequence of non-disjunction is the production of gametes that have incorrect numbers of chromosomes, either with too few or too many.
Those gametes with too few chromosomes usually perish quickly. Those with an extra chromsome can survive.
Down's syndrome is an example of a condition that is the result of non-dysjunction. In Down's syndrome chrosmomes fail to separate leading to the presence of three chromsomes of type 21 instead of two. A person with this condition will therefore have a total number of 47 chromosomes instead of 46. Down's syndrome can be diagnosed by karyotyping the person's set of chromosomes and identifying the presence of three chromosomes of type 21.see more
