Answer: The correct option is A) Enzymes lower the activation energy of a reaction.

Enzymes are also called as catalyst. They increase the rate of reaction by lowering the activation energy of the reaction. This means that they speed up the chemical reactions by doing so.

Activation energy is the minimum amount of energy required by a reactant to form an activated complex in order to initiate the chemical or nuclear reaction.

Thus, enzymes speed up the chemical reactions by lowering the activation energy.

polet [3.4K]

Answer:

6 thymine, 4 guanine. 4 cytosine

Adenine pairs with thymine, so you need 6 of each

Cytosine matches with guanine, but the total of nucleotides is 20, so

6(adenine)+6(thymine)=12

20-12=8

8= 4(guanine)+4(cytosine)

Elanso [62]

Answer: A population has a small size high level or genetic drift and very little migration into the population what will most likely happen to the genetic diversity in the population over time?

Explanation: Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations.Genetic drift may result in the loss of some alleles Genetic drift can have major effects when a population is sharply reduced in size by a natural disaster
