create an environment conducive to open development, construct a fair, equitable and transparent system of international trade and investment rules, and advance cooperation based on win-win outcomes, shared responsibility and collective participation. The...
'Natural selection' is, it seems, an ambiguous term. It is sometimes held to denote a consequence of variation, heredity, and environment, while at other times as denoting a force that creates adaptations. I argue that the latter, the force interpretation, is a redundant notion of natural ...
Species evolve through natural selection. What is natural selection? A. a process by which organisms with favorable traits survive and reproduce B. a method of artificial breeding C. a random event D. a process of rapid change 相关知识点: ...
What must be true for natural selection to happen? What is the basis of natural selection? What is variation in natural selection? What are the types of natural selection? What happens in the process of natural selection? Define natural selection and give an example in biology. ...
For natural selection to occur, there needs to be trait variation. Snowshoe hares, for example, are brown in the spring and summer months, but during the winter, their coat changes to white. There also needs to be an evolutionary advantage to the trait; any hares that do not change color...
What can natural selection lead to? A. Only the evolution of new species. B. Only changes in the characteristics of a population. C. Both the evolution of new species and changes in the characteristics of a population. D. Nothing.
Give an example of adaption in nature. What is a mutation and what role do mutations play in evolution through natural selection? What type of genetic change is most important for evolution? Based on Darwin's Theory of Evolution, which of the fo...
B 正确答案:B解析:细节题 答案在第一段的中间部分:一系列小的特征变化将不断累积,最终诞生的生物将会与其祖先存在很大差异,从而成为新的物种(…a series of small differences…they would constitute a new species.)。A,C,D三项也包含文章中已出现的词语,因此具有迷惑性,但根据上下文不难看出答案是B项。反馈...
Natural Selection is an example of a mechanism of evolution. Does the mechanism produce a change in individuals or populations? Explain! Does natural selection increase variation? How so? Explain how the theory of natural selection involves genetic variation and adaptat...
In modern biology, natural selection is a process whereby species which have traits that enable them to adapt in an environment survive and reproduce, and then pass on their genes to the next generation. Natural selection means that species that can adapt to a specific environment will grow in ...
