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.

Explanation:
To determine the charge on a given transition metal atom, you have to consider what element it is, the charges on the other atoms in the molecule, and the net charge on the molecule itself. The charges are always whole numbers, and the sum of all the atomic charges equals the charge on the molecule
Answer:
Small-scale convection currents arise from uneven heating on a smaller scale. This kind of heating occurs along a coast and in the mountains. Small-scale convection currents cause local winds. Local winds blow over a much smaller area and change direction and speed over a shorter period of time than global winds.
Maybe that will help you answer the question.
Answer:
the answer is below
Explanation:
Cirrus clouds form from the ascent of dry air, making the small quantity of water vapour in the air undergo deposition into ice (to change from a gas directly into a solid). Cirrus is made up completely of ice crystals, which provides their white colour and form in a wide range of shapes and sizes.
