Biology

aksik [14]3 years ago

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.

Korolek [52]

Leukopenia means  a low count of white blood  cells in the body. When there is a low white blood cell count in the body, and in particular a low level of neutrophils (a kind of white blood cell that fights infection), there is quite a significant risk of developing an infection, and once an infection is developed and the white blood cell count is low, the body will not be able to protect itself and fight off the infection. In severe cases , infection may lead to death.

Question 4 (1 point) If 18 grams of oxygen reacts completely with 4 grams of hydrogen, we would expect how many grams of water?
Lisa [10]

Answer:

C.22 grams because mass cannot be created or destroyed

Explanation:

Reaction equation:

        2H₂  +   O₂    →   2 H₂O

Mass of oxygen  = 18g

Mass of hydrogen  = 4g

The mass of water produced is 22g according to law of conservation of mass.

The law states that " in a chemical reaction, mass is always conserved"

 The sum of the mass of product  and reactants must always be the same.
