I know Gregor Mendel - Austrian naturalist, botanist and a religious leader, a
monk, founder of the doctrine of heredity (Mendelism). By applying statistical
methods for the analysis of results of the hybridization of pea varieties,
formulated the laws of heredity. In 1856, Mendel began his experiments in
crossing different varieties of peas, differing in a single, strictly defined
criteria (for example, the shape and color of seeds). Precise quantitative
account of all types of hybrids and statistical processing of the results of
experiments that he conducted for 10 years, allowed him to formulate the basic
laws of heredity - the splitting and combining of hereditary
"factors". Mendel showed that these factors are separated and not
crossing merge and disappear. Although the crossing of two organisms with
contrasting features (for example, yellow or green seeds) in the next
generation of hybrids appears only one of them.</span>

The chemicals, and other substances are considered as the source of water pollution.
Answer:
The complement system or complement cascade is an essential part immune system that increases the ability of the immune cells such as phagocytic cells and antibodies to kill and remove foreign bodies such as microbes and removes the damaged or infected from the cells of an infected organism.
The complement system utilizes the classic pathway to destroy cell walls or membrane of antigen or microbes, however, it sometimes also use alternate pathway for certain organism
Large numbers of activated complement proteins are produced by the complement system that binds and, opsonizing microbes for internalization by phagocytes having receptors for a complement. It is important for innate defense
