The integument is a diploid structure that is part of a/an O A) ovule
B) embryo
C) pollen grain
D) ovary
E) flower

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.

here's one link:

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
