Answer:
Explanation:
Proteins in the plasma membrane have several functions based on their components, location etc. For instance, if the protein transcends the entire plasma membrane it could be a transport protein, responsible for the import and export of certain molecules between the cell and the extracellular matrix (ECM). If the proteins are resting at the surface of the cell, facing the ECM, their role could be to detect components in the ECM, relaying a series of messages back to the nucleus so that the cell can ‘decide’ what it should do with this information (is it being told it should undergo apoptosis, should it begin to divide, should it migrate?). As well as this, it could be involved in the detection of foreign bodies such as pathogens. This is an extremely job for these proteins because if the cell does come in contact with a pathogen, the cell can use these proteins to engulf the pathogen and through a series of steps, present the antigen on their major histocompatibility complexes (either 1 or 2 depending on the cell type) or HLA’s for human cells. Thus it can be concluded that protein functions vary widely in the plasma membrane and due to the vast number of proteins that can be found there, it’s difficult to narrow down the exact main of functions of all these proteins put together.

T cells and B cells are the two main cell types that are crucial to the efforts of the adaptive immune response, in addition to cytokines and APCs.
<h3>Passive immunity is conferred by which of the following?</h3>
By supplying antibodies or lymphocytes that have already been produced by an animal or human donor, a vaccination may also impart passive protection. Most vaccines are administered parenterally (by injection), although some can also be taken orally or even nasally (in the case of flu vaccine).
Monoclonal antibodies search for and bind to the spike protein that protrudes from the coronavirus that causes COVID-19 after they have entered your body. Monoclonal antibodies that bind to the spike protein can prevent the virus from entering cells, slowing the infection.
The endothelial cell glycocalyx, which serves as a molecular sieve, and pressure gradients in the capillary beds both affect how lymph fluid is formed. toward with fluid propulsion
