To test for the keystone species hypothesis, the wolves in another region can be removed or trees can be reintroduced to see the effect on the ecosystem.
<h3>What is a keystone species?</h3>
A keystone species is an organism whose existence defines an entire ecosystem such that them, the ecosystem would be severely affected or may not exist.
Trophic cascades are events which result in serious distortions in an ecosystem as a result of the removal or addition of a top predator.
To test for the hypothesis of keystone species and trophic cascades, the wolves in another region can be removed or trees can be reintroduced to see the effect on the ecosystem.

Answer:
The answer is B, How does gravitropism affect plant growth?
Explanation:
According to Google:
"Gravitropism (also known as geotropism) is a coordinated process of differential growth by a plant or fungus in response to gravity pulling on it."
So, since the students put the pots on their sides, and they say that the bean plants bend upwards, then option B is the only logical explanation for the plants' behavior.

How the finch offspring "looks" is determined by the genes it inherits (nature) whereas the offspring will be able to learn the song from their parent (nurture). In this case, it is the male parent that teaches the song to their young. Hence, the song that the finch offspring learns is from the male finch parent which is why it remains the same as before.
Answer:
E) The reverse reaction (breakdown of EA to E+A) was favored, slowing the V max .

Explanation:
Polyadenylation is defined as the addition of poly (A) to messenger RNA. This tail is made up of several adenosine monophosphates (adenine bases). In eukaryotes, polyadenylation is part of the process in which messenger RNA is formed for subsequent translation. Therefore, it is part of the process of gene expression.
