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.
Answer:
<em>The correct option is A) sandstone aquifer</em>
Explanation:
Groundwater can simply be described as water which is present inside the Earth's surface in structures called aquifers. Aquifers are materials which have an ideal porosity and permeability which allow water to flow through them. Aquifers are materials like sand, silt or rocks.
Sandstone aquifers can trap waste particles like bacteria while allowing the water to easily flow. Hence, they can be used for sewage from a ruptures septic tank.
Answer: continental glacier
Explanation:
These glaciers are very big and they can cover large amounts of land. These can also cover very large islands. Continental glaciers are the answer.
