Answer 1

Answer:

What are you trying to say

Answer 2

Answer:

creation of variations promote survival of species even in adverse conditions.This happens as follows:

there may be some drastic changes like excessive heat or cold or sgortage of water etc. in the habitat of a species of organisms.

now if all organisms of population living in that Habitat are exactly identical then there is danger that all of them a die and no one would survive and those conditions this will eliminate species from the habitat completely.however if some variations are present in some individual organisms to tolerate excessive heat or cold or survive on

meagre water supply , then there is a is a chance for them to survive and flourish even in adverse environment. for example if there is a population of certain bacteria living in temperate water which is neither hot nor very cold and the temperature of water increases too much due to global warming then most of the bacteria will not be able to tolerate excessive heat and hence die but some bacteria which had variation to resist heat would survive and grow further.
