Question

a mutation occurs in a heart cell of a developing squirrel. the mutation disrupts the formation of a certain protein. what will most likely happen to the squirrel? a. the squirrel will be unaffected by the mutation. b. the squirrel will develop a healthy heart. c. the squirrel will have a resistance to mutagens. d. the squirrel will have a heart that does not function correctly.

Explanation:

Proteins are crucial for cell - and organ - function. A mutation in a heart cell that disrupts protein formation will likely affect heart function. Since the mutation is in a heart cell and affects protein formation there, it won't make the heart healthy, give resistance to mutagens, and it won't go unnoticed.

Answer:

D. The squirrel will have a heart that does not function correctly.
