I believe the answer is not b, because for equilibrium to occur there cannot be genetic drift. I believe the answer is not a, because gene flow is not allowed under hardy weinberg equilibrium. I believe the answer is not D, because a, and b, which are not right answers, all talk about genetic changes occuring. Since D is also a genetic change, I would say the answer is
C. Random mating occurs, which is one of the conditions to create hardy weinberg equilibrium
The same way humans do:
By breathing in oxygen and then it goes into the system and filters through and they get CO2 as a waste product just like us!
Answer:
The correct answer is - c. Larger claws would help the crab crack open the shells of the mussels so the crab can eat them.
Explanation:
The graph (attached) states that the two variables size of claws of the crabs depends on the thickness of the shell of mussels. With the increase in the thickness of the shell of the mussels the size of the claws of crabs also increases and becomes larger.
The most likely explanation of this change would be adapting according to the change in the shell of the crab as they require to crack their shell to eat them as mussels are the primary food source of these crabs.
