Answer:
shark are slow evolving species because of lower gene flow and rate if reproduction.
Darwin finches undergo divergent evolution
Explanation:
Sharks have evolved slowly because of following reasons –
a) Lower rate of reproduction
b) Restricted gene flow because of isolated habitat such as stretches of deep water
c) Staying close to the eggs and hence guarding them throughout their life thereby allowing no cross mating.
d) Lower rate of mitochondrial DNA (mtDNA) evolution
Darwin’s finches show divergent evolution as different species of finches originated from a common ancestors. The beak size of finches vary form one species to other because of different diet habits
Answer:
The answer is A.
Explanation:
The lac repressor protein can prevent or let the transcription and production of the operan. When there is lactose not present in the body, the lac repressor protein prevents the production of the operan by RNA polymerase but when lactose is present, it let's the operan to get produced . So the answer is yes, the presence of the lactose molecule controls whether the operon is on or off.
