A single change or alteration in the nucleotide base of the genetic material of the cell is called a point mutation. It can be a deletion, addition or inversion of a single nucleotide base.
In the following, the mutations that occurred are 1. C and 2. B.
<h3>How the mutation can be explained?</h3>
- <u>Silent mutation</u> occurs in a single base of the triplet codons of the bases but the alterations do not cause an observable effect and they remain as a neutral alteration. They do not affect the function of the protein. Thus, the glycine to glycine is a silent mutation.
- <u>Non-sense mutations</u> are caused when the single change in the nucleotide base results in the formation of the stop codon. Thus, lysine to stop codon is a nonsense mutation.
Therefore, silent and nonsense mutations are the correct options.

Answer:
All these factors affect gene flow:
1. Differences in animal behavior and life history strategies can form effective barriers to gene flow.
2. The home range size of the specie can also serve as a barrier to gene flow.
Explanation:
Firstly, gene flow is the transfer of genetic traits from one population to another. It is an important process for transferring genetic variations from one population to another.
There are several barriers or factors that limit or increase this gene flow.
Gene flow can be affected by mobility or rate of dispersal. It is expected to be lower in species with low mobility which is the movement from one place to another or low dispersal and vice versa. So a population with a shorter home range size can't effective aid gene flow as they interact only with individuals of the same population and vice versa.
Gene flow barrier could be by physical barriers which is the isolation of a geographical location preventing them from exchanging genetic materials with the same species of the sane population.
This type of physical barrier is usually but not always natural.
Barrier to gene flow could be reproductive preventing transfer of genectic materials due to differences in mating period, season of birth and so on.
Another barrier could be difrerneces in customs, ethnicity, religion and clans.
All these factors affect gene flow but the 3rd and 4th option are not totally true as barriers to gene flow are not totally physical geographical barriers and not totally anatomical differences but also soil preference and other factors.

The total distance the token moved is 12 cm.
Given : space on the board game measures 1 centimeter
5 cm (up) + 5 cm (left) + 2 cm (down) = 12 cm
<span>Aside from absorbing water and nutrients in the
ground, roots are also the very support of a tree. It supports bigger trees to
stand and stay steady against heavy rains and strong winds. Roots are also
capable of absorbing water that may cause flood in the area, and support slopes
that may result to landslides. Roots are very important because it lessen the
chances of soil erosion in a certain place. Roots can also be used for plant
vegetations.</span>
