Answer:
The correct answer would be gene flow.
Explanation:
Gene flow is explained as the transfer of genes from one population to another so there is an increase in their frequency of genes.
It is also called migration. The addition or loss of people can affect the frequencies of the gene pool even if no other evolutionary mechanisms working at the time.
Thus, the correct answer would be gene flow.
Answer: The answer is B: The enzyme's active site binds to and stabilizes the transition state, which decreases the activation energy of the reaction.
Explanation: An enzyme is a biological molecule which speeds up the rate of chemical reactions in the body (reactions within cells). They are proteins.
The transition state is the transition from substrate to product. The molecule is no longer a substrate but also not yet a product.
The enzyme is able to speed up the reaction by stabilizing the transition state. The transition state's energy is also the activation energy in terms of reaction. The activation energy is the minimum energy that is required to break some bonds of the reactants in order to turn them to products.

Answer: To be able to reach the food they need.
Explanation:
Giraffes feed off of high trees. In order to get that food, they were forced to naturally adapt to the height of the trees.
