Answer:
Geographical Isolation
Explanation:
Lava serves as geographical barrier to separate the two populations of monkey. These two isolated populations accumulate variations and gradually become reproductively isolated. Reproductive isolation brought about by geographical isolation leads to formation allopatric species which are now present in different geographical regions.
One of the negative impacts of eutrophication and increased algal growth is a Loss of oxygen known as anoxia
I’m not sure but it might be the third one
Answer:
A. Yes, because the %A approximately equals the %T and the %G approximately equals the %C in both species.
Explanation:
According to Chargaff's rule, in all cellular DNAs, the number of adenosine residues (A) is equal to the number of thymidine residues (T). And the number of guanosine residues (G) is equal to the number of cytidine residues (C). Therefore, the sum of the purine residues equals the sum of the pyrimidine residues (A+ G= C+ T). It is based on the fact that a purine base always pairs with a pyrimidine base in a double helix DNA.
Chargaff’s rule is followed in all the double-helical DNA molecules irrespective of the species. In DNAs of sea urchin and salmon, the percentage of adenine is equal to that of the thymine and the percentage of guanine is equal to that of the cytosine. Therefore, Chargaff's rule is followed.
