Answer:
A .They result in sudden gene frequency changes.
Explanation:
Answer:
Three nucleotide
Explanation:
Three nucleotides are required to code for one amino acid. There are four types of nucleotides A, T, G, C which make DNA. So a doublet of nucleotide code which involves only two nucleotide would be insufficient to code for 20 amino acids because if 4 different nucleotide is taken two at a time then it can only produce 16 amino acid(4²=16).
But if we take three-nucleotide than the number reaches 64 which is more than sufficient to code for 20 different amino acids(4³= 64). Therefore 3 nucleotides are needed to code for an amino acid.

Helix formation would be favored at high pH.
Explanation:
Answer:Flippered and charismatic, pinnipeds (which includes seals, sea lions, and walruses) are true personalities of the sea. Like whales, manatees, and sea otters, they are marine mammals, meaning millions of years ago their ancestors evolved from a life on land to a life at sea. Today, they remain creatures of both land and sea. Though able to walk on land, they are truly at home in the water. Strong flippers and tails propel them and a streamlined body helps them cut through the water efficiently.
It’s easy to tell the enormous, tusked walrus from other pinnipeds, but seals and sea lions are easy to confuse. The easiest way is to look at their ears—sea lions have small ear flaps while seal ears are nothing but small holes.
