Which of the following is true about mutation?
a. Mutation comes from artificial selection.
b. Mutation is always harmful to an organism’s survival.
c. Mutation is always helpful to an organism’s survival.
d. Mutation can come from environmental changes.

Respuesta :

I’m almost 100% sure it’s D, because environmental factors can induce a mutation. A mutation can be beneficial but it can also be harmful, so it’s neither B or C, and it can’t be A, because mutations can come from natural selection as well. So it’s D.
