I would select A because cells have to divide into smaller cells depending on where they are.
Answer:
Competition is an interaction between organisms or species in which both the organisms or species are harmed. Limited supply of at least one resource (such as food, water, and territory) used by both can be a factor.

tungsten metal is the strongest metal.
An organ is a body structure composed of tissues that have related functions. The human body has levels of organization. <span>The cell is the basic structural and functional unit of a living organism which communicates with different and similar cells in order to work together and carry out all physiological processes. <span>Cells with similar structures are grouped together in a tissue to perform a shared function. A group of tissues forms an organ that together with other organs make organ system. The integrated activity of all the organ systems makes the whole organism.</span></span>
Answer:
e. Epistatic interaction of the two genes
Explanation:
The 9:7 ratio is typical of the Duplicate Recessive Epistasis.
The expected phenotypic ratiio of the offsrping of a dihybrid cross is:
9 A_B_
3 A_bb
3 aaB_
1 aabb
In the Duplicate Recessive Epistasis, the A_bb, aaB_ and aabb individuals all have the same phenotype, making for the ratio 9:7. What those three genotypes have in common is that in all of them at least one of the two genes is homozygous recessive (either <em>aa</em> or <em>bb</em>).
This usually happens one the products of genes A and B are enzymes of the same metabolic pathway.
Whenever both A and B are present, the pathway can produce the final product and a certain phenotype. However, if any of the dominant alleles is missing, the enzyme is not produced and therefore the final product of pathway is not produced, giving the other phenotype.
