Blue poppies native to China are grown at a plant-breeding center in California. Those with the thickest leaves survive and reproduce best in California's drier climate.

This evolutionary adaptation of the poppies to their new environment is due to .

a) genetic drift

b) neutral variation

c) disruptive selection

d) directional selection

e) stabilizing selection

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.

the answer is d p: cell, q: organ, r: organ system, s: tissue
