Select the correct answer. _____enable long-term resistance to infections that have been present in the body before. A. Monocyte

Alekssandra [29.7K]

Answer:

C. Lymphocytes

Explanation:

All of the following choices are kinds of white blood cells that have a significant role in the body's immune system.

A. Monocytes

Monocytes defend the body against infection by acting as macrophages. They are capable of eating up foreign bodies that may cause infection.

B. Neutrophils

Neutrophils are the most in number in the body's immune system, especially when there is inflammation. They are distributed to different areas where they can move through circulation along blood vessels. They specifically attack antigens.

C. Lymphocytes

Lymphocytes are further divided into two. These are the B cells and the T cells. The B cells are also of two kinds. One of them is the memory B cells, which can remember a foreign body and create antibodies against it to provide for a long-term resistance in case the body gets exposed to the same infectious agent again.

D. Basophils

As part of the immune system, basophils function for preventing blood clots as well as in mediating allergic reactions.

Please help balance <br> _Ch7H16+_O2=_CO2+_H2O

iren2701 [21]

Answer:

C7H16 + 11 O2 → 7 CO2 + 8 H2O

This is an oxidation-reduction (redox) reaction:

7 C-16/7 - 44 e- → 7 CIV (oxidation)

22 O0 + 44 e- → 22 O-II (reduction)

C7H16 is a reducing agent, O2 is an oxidizing agent.
