23.
If an environment suddenly changes, which type of reproduction would be most beneficial? Why?
a)
Asexual, because asexual organisms always have variation within species.
b)
Sexual, because sexual organisms have variation within species.
c)
Both Asexual and Sexual reproduction would be beneficial, because they both have variation within species.
