Cells such as neurons, which rarely if ever divide, can be explained as
lawyer [7]
G0 phase cells

The mitotic cycle of somatic, or body, cells is responsible for the production of copies of those cells. The mitotic cycle has different phases, each of which involves a different set of physiological changes to the cell. The G0 phase is described as the resting phase of a cell, where no activities relating to cell division are taking place. G0 phase cells remain in this phase their entire lives, so they do not divide. Another example of such a cell is found in red blood cells.

Be able to compare/contrast humoral immunity with cellular immunity.
aksik [14]

Solution:

The difference between them are:


The humoral system of immunity is also called the antibody-mediated system because of its use of specific immune-system structures called antibodies. The first stage in the humoral pathway of immunity is the ingestion (phagocytosis) of foreign matter by special blood cells called macrophages. The macrophages digest the infectious agent and then display some of its components on their surfaces. Cells called helper-T cells recognize this presentation, activate their immune response, and multiply rapidly. While,


The cell-mediated immune response involves cytotoxic T-cells, or killer-T cells. Body cells that have been infected by foreign matter often present components of that material on their surfaces. Killer-T cells recognize these displays and respond by ingesting or otherwise destroying the infected cell. Killer-T cells are also important in the body's defenses against parasites, fungi, protozoans, and other larger cells that might have found their way into the body. The killer-T cells recognize these large invaders by their foreign proteins and then destroy them.  

This is the required answer.
