<span>There are different types of B cell and T cell. both are lymphocytes, a subclass </span><span>of white blood cell. the T cells are mainly used in identifying antigens and </span><span>releasing chemicals which attack macrophages (big immune cells which 'eat' </span>antigens), to destroy the antigen. B cells are used in the <span>antibodies. When they encounter a new antigen, plasma cells and memory cells are </span>antibodies. <span>Formed from the division of a B cell. the memory cell remembers the antigen and </span><span>which antibody to use, while the plasma cell makes the antibodies to fight a </span><span>particular antigen or class of antigens.
</span> Hope this could help you with your question. : )

Answer:

Explanation:

Lymphocytes are a class of white blood cell in the body's immune system. B-cell and T-cell lymphocytes are types of lymphocytes.

There are differences between the T-cell lymphocytes and the B-cell lymphocytes. The major differences are

T-cell lymphocytes are produced in the thymus while B-cell lymphocytes are produced in the bone marrow
T-cell lymphocytes are involved in cell-mediated immunity while B-cell lymphocytes are involved in humoral immunity

A tank with volume of 2.4 cu ft is filled with Methane to a pressure of 1500 psia at 104 degrees F. Determine the molecular weig

Soloha48 [4]

Explanation:

It is known that equation for ideal gas is as follows.

PV = nRT

The given data is as follows.

Pressure, P = 1500 psia, Temperature, T = $104^{o}F$ = 104 + 460 = 564 R

Volume, V = 2.4 cubic ft, R = 10.73 $psia ft^{3}/lb mol R$

Also, we know that number of moles is equal to mass divided by molar mass of the gas.

n = $\frac{mass}{\text{molar mass}}$

m = $n \times W$

= $0.594 \times 16.04$

= 9.54 lb

Hence, molecular weight of the gas is 9.54 lb.

We will calculate the density as follows.

d = $\frac{PM}{RT}$

= $\frac{1500 \times 16.04}{10.73 \times 564}$

= 3.975 $lb/ft^{3}$

Now, calculate the specific gravity of the gas as follows.

Specific gravity relative to air = $\frac{\text{density of methane}}{\text{density of air}}$

= $\frac{3.975 lb/ft^{3}}{0.0765 lb/ft^{3}}$

= 51.96

What is the affect of increasing the water's mass?how does it reflect it's temperature?

Nikolay [14]

I assume what you're asking about is, how does the temperature changes when we increase water's mass, according the formula for heat ?
Well the formula is : $Q=m\cdot c\cdot \Delta t$ (where Q is heat, m is mass, c is specific heat and $\Delta t$ is change in temperature. So according this formula, increasing mass will increase the substance's heat, but won't effect it's temperature since they are not related. Unless, if you want to keep the substance's heat constant, in that case when you increase it's mass you will have to decrease the temperature

A engineer measures the peak power output is 0.3227MW what is the peak power output in kilowatts ?

Lana71 [14]

<h3>Answer:</h3>

322.7 kW

<h3>Explanation:</h3>

Power refers to the rate at which work is done.
Therefore; Power = Work done ÷ time
It is measured in joules per seconds or Watts

In this case, we are required to convert 0.3227 MW to kilowatts

We need to know that;

10^6 watts = 1 Megawatts(MW)
10^3 Watts = 1 kilowatts (kW)

Therefore;

10^3 kW = 1 MW

Therefore, the suitable conversion factor is 10^3kW/MW

Hence;

0.3227 MW is equivalent to;

= 0.3227 MW × 10^3kW/MW

= 322.7 kW

Thus, the peak power output is 322.7 kW

Identify the classification of milk a aerosol b solid emulsion c solid aerosol d foam e emulsion

enot [183]

option (c) emulsion is the right answer

Emulsion is a classification of milk.

<h3>Describe an emulsion.</h3>

In physical chemistry, an emulsion is a combination of two or more liquids in which one of the liquids is present as microscopic or ultramicroscopic droplets dispersed throughout the other.

<h3>How is emulsion used?</h3>

Emulsions form as a result of the cleansing action of soaps.

(ii) The emulsification process is how lipids are broken down in the intestines.

(iii) Disinfectants and antiseptics combine with water to generate emulsions.

(iv) The emulsification technique is utilized to create medications.

<h3>How is an emulsion created?</h3>

When two immiscible liquids, such as oil and water, are stirred together with an emulsifier—which might be a protein, phospholipid, or even a nanoparticle—emulsion is created.
