Answer:
Immune system of the body helps in fighting with the infectious agents that are foreign for the body. So the immune system protects us from infection.
When any foreign substance(antigen) comes in the body B-lymphocyte recognize it by binding the antigen through its receptor. After recognizing the antigen, B cell divides into antibody-producing plasma cell and memory cell.
Antibodies produced by plasma cells help in destroying the antigen by getting the antigen recognized by phagocytic cells or by complement activation.
B cells are antigen-presenting cell which present antigen to T cell and then T cell activates and produce chemicals that kill the antigen. Therefore the immune system has many immune cells that activate when an antigen comes in the body. This is how the immune system functions.
The non Mendelian inheritance pattern observed in snail coiling is most related to maternal inheritance.
<h3>Why is genetic inheritance important? </h3>
Genetic inheritance is necessary for evolutionary change. It describes how genes are passed from one generation to the next.It might consequently initially seem surprising then, that genetic inheritance itself is rarely inculded in life research.
The phenotype controlled by organelle genes exhibit maternal inheritance.The classic phenotype which exhibits maternal effects is coiling direction of snail shell.The phenotype that is seen in the offspring is controlled by the genotype of the mother.

Some scientists hypothesize that the eukaryotic cells are really the result of symbiotic processes!
Specifically, the internal organs of the cells could be a remnant of a symbiotic relationship in which one cell lived inside of another cell. These two cells then both split upon reproduction and eventually the cell inside was reduced to an organelle.
But according to this theory, it is very likely that the prokaryotic cells engaged in a number of symbiotic relationship, and that this actually lead to the emergence of eukaryotic cells!
