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.
The spinal leaves the skull through the foramen magnum, and then goes into the vertebral column the first vertebra is called the ATLAS
Putting it in ice would decrease the flow of blood, aka "numbing the sever," which would not only decrease the loss of blood but the chances of the cells dying.
Answer:
The correct answer would be the experimental group.
There are mainly two groups present in any experiment; the experimental group and the control group.
The experimental group refers to the group which receives experimental procedures or is exposed to the independent variables to be tested.
In contrast, the control group refers to the group which is kept in controlled conditions, that is, it is not exposed to the variables which are being tested.
