<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

How many grams of H2SO4 are needed to prepare 500. mL of a .250M solution?
zavuch27 [327]

Answer:

We need 12.26 grams H2SO4

Explanation:

Step 1: Data given

Volume of a H2SO4 solution = 500 mL = 0.500 L

Concentration of the H2SO4 solution = 0.250 M

Molar mass of H2SO4 = 98.08 g/mol

Step 2: Calculate moles H2SO4

Moles H2SO4 = concentration * volume

Moles H2SO4 = 0.250 M * 0.500 L

Moles H2SO4 = 0.125 moles

Step 3: Calculate mass of H2SO4

Mass of H2SO4 = moles * molar mass

Mass of H2SO4 = 0.125 moles * 98.08 g/mol

Mass of H2SO4 = 12.26 grams

We need 12.26 grams H2SO4

Use water as an example to contrast the properties of a compound with the elements from which it is composed
ahrayia [7]
Properties of a compound is completely different from their elements.

Water is composed by hydrogen and oxygen.

For example, the boiling point of oxygen is - 183 °C and hydrogen is - 253 °C, meanwhile, water has a boiling point of 100°C

Another example is when you put a burning wooden splint into oxygen, it burns more brightly. Put it in hydrogen, you may hear a "pop" sound, or even explode when large amount of hydrogen. But if u put a burning splint in water, it goes off.

A race car travels on a circular track at an average rate of 125 mi/h. The radius of the track is 0.320 miles. What is the centr
IRISSAK [1]
<h3><u>Answer;</u></h3>

<em><u> = 48,828.125 mi/hr²</u></em>

<h3><u>Explanation and solution</u>;</h3>
  • <em><u>Centripetal acceleration is the rate of change of angular velocity. Centripetal acceleration occurs towards the center of the circular path along the radius of the circular path</u></em>.
  • Centripetal acceleration is given by; <em>V²/r ; </em>

<em>V = 125 mi/h and r = 0.320 miles </em>

  • <em>Thus; centripetal acceleration = 125²/0.320 </em>

                                                  =15625/0.320

                                                 <em><u> = 48,828.125 mi/hr²</u></em>
