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.

Under certain conditions Argon gas diffuses at a rate of 3.2 cm per second under the same conditions an unknown gas diffuses at
kozerog [31]

Answer:

20 g/mol

Explanation:

We can use <em>Graham’s Law of diffusion</em>:

The rate of diffusion (<em>r</em>) of a gas is inversely proportional to the square root of its molar mass (<em>M</em>).

r = \frac{1 }{\sqrt{M}}

If you have two gases, the ratio of their rates of diffusion is

\frac{r_{2}}{r_{1}} = \sqrt{\frac{M_{1}}{M_{2}}}

Squaring both sides, we get

(\frac{r_{2}}{r_{1}})^{2} = \frac{M_{1}}{M_{2}}

Solve for <em>M</em>₂:

M_{2} = M_{1} \times (\frac{r_{1}}{r_{2}})^{2}

M_{2} = \text{39.95 g/mol} \times (\frac{\text{3.2 cm/s}}{\text{4.5 cm/s}})^{2}= \text{39.95 g/mol} \times (0.711 )^{2}

= \text{39.95 g/mol} \times 0.506 = \textbf{20 g/mol}

Leno4ka [110]

Answer:

It helps the body remove heat through sweating.

Explanation:

When the weather is hot, the body tries to keep cool by sweating. The high specific heat capacity means that the body doesn't have to lose much water to stay cool.

The high specific heat capacity of water doesn’t heat the body, but it slows down the rate of heat loss when the weather is cool.

B is wrong. The body uses glucose, not water, as an energy source.

C is wrong. The high specific heat capacity of water is not connected with the body's ability to store it.

D is wrong. The high specific heat capacity of water doesn't heat the body, but it slows the rate at which it cools.
