Which of the following best describes why the process of evolution is easier to study in fruit flies than in birds?

Because fruit flies have small cell counts Because the life cycle of a fruit fly is short enough to actually see a change in a short period of time. With larger animals, it could take many years to see an actual change. With fruit flies, you can see many generations of change in a shorter period of time.

Concept of evolution?
Evolution can be a confusing term because it is used in more than one way. Many people in the general population have developed an incorrect understanding of evolution for a number of reasons. One is the misinformation spread by creationists - by misrepresenting evolution, they may hope that it will be easier to get people to disregard it. Another is simple ignorance of the topic itself and the specific ways in which science uses certain terminology.Because evolution is so complex, however, it is important to get a handle on the different ways in which the term can be used. There are, of course, broader uses - we can talk about the evolution of the universe or the evolution of the planet Earth. In such cases, evolution simply refers to change over time, but that isn't what concerns us here.Biology, in contrast, uses the term evolution a bit more specifically. At its most basic, evolution in biology can be used to refer either to the change in the gene pool of a population over time or to the concept of descent with modification. Here are some examples from basic biology texts:"In fact, evolution can be precisely defined as any change in the frequency of alleles within a gene pool from one generation to the next." Helena Curtis and N. Sue Barnes, Biology, 5th ed. 1989."Biological evolution ...is change in the properties of populations of organisms that transcend the lifetime of a single individual." Douglas J. Futuyma in Evolutionary Biology, 1986.The two definitions look a bit different, but they are expressing similar things - the first is to a large extent more technical. An allele is a particular form of a gene and if a single gene is responsible for eye color, then one allele is for brown eyes, another allele is for blue eyes, and so on.So, if the frequency of the allele for blue eyes changes in a population over time, that means that evolution has taken place. This may not seem like a very significant step in evolution, but the fact of the matter is most evolutionary steps are quite small - large changes are the result of many, many smaller steps.The second common use of the term evolution within biology is for the concept of common descent, the idea that all living beings are descended from a common ancestor. This typically occurs in the context of allele frequencies changing in populations over time, but there are also other factors as well. Thus, "change in allele frequency over time" is a narrow and technical definition of evolution while "descent with modification" is a broader understanding.Lance F. contributed information for this.
Why do scientists use physical characteristics instead of animal behavior to classify and group animals?
Scientists use physical characteristics instead of animal behaviour to classify and group animals because physical characteristics are more definable than behaviour. Behaviour within a group of animals varies a lot, even within a single species. However, common physical characteristics are much easier to find and understand, as well as making the evolutionary process easier to see and understand. "Evolution never suggests that one thing ever turned into another fundamentally different thing. Every new species or genus, (etc.) that ever evolved was just a modified version of whatever its ancestors were." Because of this, they group and classify animals to study this and better name them. Grouping animals by all having fur or being quadrapods is much easier and makes more sense than classifying an organism by "grooms others as show of affection". Animal behaviour is also subjective.
What does genetic technology make it easier to give cows growth hormones?
Genetic technology makes it easier to give cows growth hormones. This is because it is now easier to transfer the hormones.
Why did the evolution of tetrapods occur?
It is unknown what caused such evolution to occur. We do know that they evolved from some sort of lungfish. The ability for a fish to take oxygen from the air makes it easier to survive in water without much dissolved oxygen. Possible transitional fossils show animals with leg-like fins that could not support the animal's weight on land, but might have been useful for crawling along the bottoms of shallow lakes. The ability for a similar animal with stronger limbs to crawl onto land would have allowed them to escape predators and move to new bodies of water if conditions become unsuitable.
