Answer: False
Explanation: The COMPLEMENT SYSTEM consists of proteins synthesized in the liver. They are activated by inespecific harmful substance (antigen) and begins a cascade of proteins that finally forms an attack complex against bacteria.
The COMPLEMENT is part of the INNATE IMMUNITY, because it is an inherent response, something all humans born with, and it is part of the first defense barrier against any antigen. Part of the innate immunity are too: natural killer cells, neutrophils, monocytes, dendritic cells and macrophages.
On the other hand, the ADAPTATIVE IMMUNITY, is the response that the body develops after being exposed to an antigen before. It is like something that the body recognizes, and then "learns" how to act against it. Part of the adaptative immunity are: lymphocyte T and B, and the antibodies (substances called Immunoglobulins). The immunoglobulins (Ig) are glycoproteins present in the blood.

<span>Pancreas. The pancreas does so by having beta cells that secrete a certain amount of insulin after consumption of food. There are then delta cells that regulate the beta cells, and then gamma cells that in turn regulate the delta cells.</span>
Answer:
The correct answer will be option-A
Explanation:
The Mosses are the non-vascular plants that were developed from the aquatic plants and the ferns are the vascular plants which developed from the bryophytes.
Their life cycle shows alternation of generation and is largely dependent on the water for reproduction mainly fertilization or fusion of gametes.
The male gametes produced in these plant groups are haploid and are released in water which fuses in water with female gamete which is distinct from the higher plant groups gymnosperms and angiosperms where fertilization is mediated by mostly the wind or insects.
Thus, option-A is the correct answer.
The answer is chromosome ....
