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.
Dear public, our ecosystem is being ruined and we need to stop it, i think you should do something about the littering and loitering in our community and in the U.S. it would help a lot of people if you made a law against it or if we went out and all did community service and helped pick up. if you don't like these ideas we could protest, but all me and my fellow people ask is that you help our <span><span>ecosystem for better lives for everyone! yours truly, citizen</span></span>
The step that is part in the
formation of the batholiths is a single pluton enlarges into a huge mass by melting
the rock around it. A single pluton does not enlarge into a huge mass, instead,
it will melt due to the buoyant magma that surrounds it.
<span>B is the correct answer. Multicellular organisms, as with almost all organisms, begin life as a single cell. The increase in the number of cells can be as a result of cell division or cells combining together. </span>
