Answer:
4
Explanation:
According to Mendel's law of purity of gametes, each gamete contains single allele for a gene. The alleles of a gene segregate during gamete formation and each gamete has one allele for a gene irrespective of the total number of alleles for a gene.
If the gene for skin color in a fish species has four alleles, an individuals fish would have only two alleles which in turn would segregate during gamete formation.
Since there are four different alleles of the gene (let's assume a,b,c, and d), total possible gametes produced by this organism will be = 4. A gamete can have one of the total 4 alleles making total 4 types of the gametes each with a or b or c or d allele.
Answer:
Appositional growth occurs within the periosteum . In this process, osteoblasts in the inner cellular layer of the periosteum produce and deposit bone matrix within layers parallel to the surface, called external circumferential lamellae. These lamellae are analogous to tree rings: As they increase in number, the structure increases in diameter. Thus, the bone becomes wider as new bone is laid down at its periphery. As this new bone is being laid down, osteoclasts along the medullary cavity resorb bone matrix, creating an expanding space.

Answer:
<h2>A</h2>
Explanation:
Pepsinogen is an inactive enzyme which is activated into active digestive enzyme known as pepsin. It is a digestive enzyme which causes breakdown of proteins. Active pepsin causes cleavage of more pepsinogen molecule by a positive feedback loop and leads to increase in the concentration of active pepsin molecule.
Its concentration increases according the requirement in the body which is controlled by feedback system.
