Answer:
Presence of specific antigen receptors on the surface of Immunocompetent B and T cells make them to generate immune response against specific antigens only.
Explanation:
The cellular and antibody-mediated immune responses are specific in nature. This means these immune responses are generated for particular foreign molecules or antigens only. These immune responses include B and T lymphocytes. Before T cells leave the thymus or B cells leave the red bone marrow, they develop immunocompetence. Immunocompetence is the ability to carry out adaptive immune responses. During this process. B cells and T cells make distinctive proteins and insert them into their plasma membranes. Some of these proteins function as antigen receptors capable of recognizing specific antigens. This is why the B and T cell-mediated third line of defense are specific in nature.
For example, antibody-mediated immune responses generate the memory cells for most previously encountered antigens to ensure the generation of more rapid and vigorous response during any further encounter with the same antigen.
Answer:
Heriditary
Explanation:
Heriditary traits are genetic traits that get passed down.
Answer: See explanation below
Explanation:
Tributyrin agar Is the inability of this medium to distinguish between these different enzymes a weakness in its specificity or its sensitivity.
Lipases break down lipids (fats).
Tributyrin oil is a type of lipid called a triglyceride. Other lipase tests use different fat sources such as corn oil, olive oil, peanut oil, egg yolk, and soybean oil.
Lipase allows the organisms that produce it to break down lipids into smaller fragments. Triglycerides are composed of glycerol and three fatty acids. These get broken apart and may be converted into a variety of end-products that could be used by the cell in energy production or other process.
Tributyrin oil forms an opaque suspension in the agar. When an organism produces lipase and breaks down the tributyrin, a clear halo surrounds the areas where the lipase-producing organism has grown.
Answer:
help to form a plug to stop bleeding during hemostasis
Explanation:
Platelets are one of the three types of blood cells. Platelets are involved in the formation of blood clots. Platelet vesicles have clotting factors and other substances required for the formation of a platelet plug during homeostasis. A break or damage in the lining of blood vessels exposes the underlying collagen fibers and the connective tissues. Platelets adhere to these fibers to initiate the formation of a platelet plug. These adhered platelets release substances to trigger the other platelets to join and form aggregate. This aggregate of platelets is called a platelet plug.
