Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
The genetic information can be transferred from one specie to the other and when it is transferred , the specie has certain similar characteristic like the original specie from whom the the genetic information has been transferred.
<u>Explanation:</u>
The genetic information can be transferred from one specie to the other specie. But it is not a true type of transfer because in this process there is only one specie who is getting the information.
This process of transferring the genetic information is known as the transgenic. By introducing new genetic material into a cell or an individual, that individual has new characteristics, that it never had before.
It has to be a, b or d then.

Answer:
21 minutes or 0.35 hours
Explanation:
The formula for exponential population growth is

where
initial population of E.coli i.e 100
k is the rate of population growth i.e 2 as the population doubles
t is the time period i.e 20 minutes
Substituting the given values in above equation, we get -

Generation time
minutes
or 0.35 hours
