Answer:
Adaptive immune responses are triggered by activation of antigen-specific T cells that produce antibodies against foreign antigens such as, for example, harmful viruses. These immune responses are useful to eliminate dangerous molecules from the body. In a normal immune reaction, the antibodies produced by T-cells target antigen molecules in order to be subsequently absorbed by phagocytic macrophage cells.
Autoimmune diseases are triggered by the response of the adaptive immune system against self-antigen molecules. Since the immune system can not eliminate antigens from the own body, this immune reaction generates an excessive inflammatory response, and it may lead to the damage of tissues and organs.
The right answer is B.
Starch is, along with cellulose, the most common polysaccharide in the plant world. It constitutes the essential energy reserves of plants and is a component of the diet of humans. It is part of the group of slow sugars. Its consumption is particularly recommended to those who practice a sport.
Glycogen, which is a polysaccharide, is the form in which carbohydrates are stored in the body (animals and fungi). Glycogen is broken down into glucose molecules when the body needs energy.
