Answer:
The correct answer would be 30 million years.
The molecular clock is a technique used to determine the time when the two species diverged from a common ancestor. It uses the mutation rate to determine the same.
Mutation rate is the rate at which a number of mutations take place in a given unit time.
For example, the mutation rate in a given question is one mutation per 10 million years, that is, one nucleotide is mutated in 10 million years.
If we compare the DNA sequence of the given two species, we would find that three mutations have taken place.
Species A: CTTAAGCTAGTAAGGACC
Species B: CATAAGTTAGTAAGGTCC
Thus, 30 million years would have passed to evolve three mutations.
Hence, they must have shared a common ancestor around 30 million years ago.

Answer:
lenses can be used for diffrent types of surgery
The term fluid implies that structures within or in the plasma membrane is able to transverse across the membrane freely. The term mosaic implies that proteins and carbohydrates on the plasma membrane are randomly scattered across the plasma membrane in no particular order.
