In plants and animals, sexual reproduction causes variation within a species. This variation is
vital to their survival. How does genetic variation affect a species' survival?

Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.

Genetic diversity serves as a way for populations to adapt to changing environments. With more variation, it is more likely that some individuals in a population will possess variations of alleles that are suited for the environment. Those individuals are more likely to survive to produce offspring bearing that allele.

answer by yourhope:

hi! : )

in which structure in the nucleus are ribosomes made?

b) nucleolus!

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

here's one link:
