Answer:
The word acidification can be misleading because a pH of 7.9 is still considered slightly alkaline. However, as the graphs in these three locations show, as CO2 rises, the pH drops, moving in the direction of the acidic end of the pH scale.

I think the answer would be yes, the nuclear membrane would be present. It is involved during the process of cytokinesis and is remain unchanged even the process is done. It is a very important part in order to have a healthy cell function.
Answer:
C) The ancestral population probably had this type of blood pigment, but it was lost through genetic drift in the other 29 populations.
Explanation:
The presence of a blood pigment that is extraordinarily effective at carrying oxygen is a beneficial genetic trait and should be favored by natural selection. According to the given information, the organisms of only a single population of pupfish have this trait while the others do not have it.
This means that the trait was present in the ancestral populations of the pupfish but was lost in the other populations due to some accidental/chance event. Loss or fixing of an allele by a chance event is called genetic drift. It does not include any natural selection but results in a random change in the allele frequencies of a population. Therefore, loss of the trait by genetic trait might have occurred in the other populations.
