Cellular differentiation describes how different cells perform different processes and have unique functions. There are at least 250 cells in the human body and each one plays a different role, and <em>all</em> of them are crucial to the body's ability to maintain homeostasis. For example, liver cells produce proteins that are important in blood clotting. If these cells are damaged, blood will not clot properly. If blood does not clot, a body cannot maintain homeostasis and the person will fall ill.
TL;DR: every cell plays its part and keeps the organism alive.
Answer:
Ostia are tiny pores present all over the body of sponges. its function is to let the water, along with desire nutrient flows interior of the sponges.
Answer:
The process of Mitosis ensures that each new cell receives the proper of chromosomes
If someone has blood type A, they must have atleast one copy of the A allele, but they could have two copies. Their genotype is either AA or AO. while an individual with blood type B will have a genotype of either BB or BO. Individuals with type O blood will have a genotype OO. Both A and B alleles are dominant over O.
Therefore, the genotype of the man is AO, that of the mother is BO, while that of the child is OO.
In future from this marriage, the possible genotypes are;
AO, BO, AB, or OO
In the frequency of 1/4 each.
