Hi, in this answer we are going to select an option that completes the given set of fill in the plants.
00:06
So we are going to select a term that creates diversity in life and a term which shapes population with organisms having characteristics that increases the rate of survival.
00:27
So we are going to identify the terms from the given options.
00:30
So diversity of life is brought about by genetic variation and genetic variation in turn is brought about by mutations.
00:45
So mutations they are responsible for changing the dna sequence of an organisms thereby producing new characteristics in an organism.
00:58
So the change in the dna sequence can introduce new allele.
01:03
Which can lead to genetic variation.
01:07
So the new characteristics if they are helping in adapting to the environment, then they are selected and passed on to the future generations, thereby creating genetic variation.
01:24
Natural selection which is also called as selection is the basic theory of evolution where the organisms which have advantageous trades are selected and if these trades are able to help the organisms to adapt to the environment, those organisms survive and reproduce more to pass on these traits to the future generations.
01:59
So this is the basis of natural selection.
02:03
Option a which says the first blank is selection or the first term is selection and the second term is mutation is a wrong option because selection does not lead to genetic variation...
