When we say homeothermic, we mean that they are able to sustain a constant body temperature regardless of the wide range of environment temperatures. Although, it's impacted within time-to-time. They are able to maintain a steady body temperature, regardless of external temperatures. If you have any questions, ask me! I hope I helped you.<span />
Answer:
The statement which is correct is
<em>The evolutionary fitness associated with the heritable trait of DDT resistance changed once DDT use became widespread.</em>
Explanation:
In the 1930's, the usage if insecticides was minimal. Hence, the genes for DDT resistance were absent or silent in the fruit flies at that time.
In the 1960's, the DDT resistant forms of fruit fly began occurring at this rate because they were better adapted to survive. According to Darwin, the species which are better able to adapt to the environment survive and are able to reproduce. Hence, with the passage of time the resistant forms of fruit fly will keep reproducing and increase in number.
