3. Did the moths change color over this time period?
AURORKA [14]
I believe that I know what you are talking about however a better layout or source would be nice.
3:I’m sorry I’m not really sure how to answer this one but I’m going to assume that you mean from dark to light. So they liked this time period because the trees were darker due to pollution, this made the darker moths survive from predators while the lighter color moths would be eaten, over time, natural selection would do its course and the whole population of moths would be dark.
4:Well I kind of already answered this but the majority of them were dark because the lighter ones would not be camouflaged therefore making them be easier target for predators and makes the darker moths breed out the lighter ones.
5:Well giraffes cannot live without food so the giraffes with shorter necks would slowly die off making it so only the long necked one would be able to reproduce with babies which would also have long necks, over a long course of time, the shorter necks would be completely gone.
6:Well I wouldn’t say they “grow” longer necks. It’s more like genetic mutation made it so random giraffes would get longer necks then others, since giraffes live in an environment where they have to have long necks only the giraffes with that genetic mutation would survive, and as a said, the longer neck giraffes could only breed with the other Long necked giraffes cause those are the only ones that could survive.

san4es73 [151]

Proximate; mechanistic best describes the class of questions that Insel and Young were addressing when they studied the effect of anti-diuretic hormone on monogamous voles.

Explanation:

Genetic researchers, Insel and Young, conducted various studies to analyze the neurobiological aspects of pair bonding on monogamous voles. This was done by studying the changes observed due to the action of the antidiuretic hormone, vasopressin, when their receptors were increased. The transgenic voles exhibited differential gene expressions which explained the proximate and mechanistic mating behavior.

The role of the antidiuretic hormone explained the neurochemical mechanisms of the voles mating behaviors like bonding, attachment etc. Rather than increasing the amount of hormone, just by increasing the receptors of the hormone, male voles showed an increased social reproductive behavior.
