Answer: The right answer is -
A) Gene flow
Explanation:
Gene flow is a process of gene migration or the transfer of gene variant (also called allele, which is responsible for genetic variation in population) from one population to another population.
As a consequence of gene migration, new alleles are introduced or added in the already existing population, thereby increasing genetic diversity.
Thus, option A) is the right answer.
Answer: Option A
Explanation:
A paraphyletic group can be defined as the group of organism that includes the ancestors but not all of its descendants.
There are three kinds of phylogenetic groups that can be understood by the help of the diagram.
The phylogeny can be defined as the diagram which shows the evolutionary relationship of one organism from another.
Other groups are monophyletic groups, parsimonious et cetera which shows different evolutionary relationship with organisms.
Answer:This type of plate is Convergent plate boundary.
Explanation:from this figure we can see that two plates meet together and one of this plates go under the other plate and this represent the convergent plate boundary.
Answer:
rising into the atmosphere, cooling and changing into a liquid form.
Because as natural selection occurs and species mate and create offspring this leads to a change in DNA which can lead to new species or evolutionists versions of that species
