<h2>GREETINGS!</h2><h2>_____________________________________</h2>

<u>ANSWER</u><u>:</u>

<h2><u>DEFINITIONS</u></h2><h2>_____________________________________</h2><h3><u>VOLUNTARY MUSCLES:</u></h3>

Voluntary muscles are those muscles which work under our conscious control and can be controlled at will also we can choose choose them when to use and when not to use. These are simply SKELETAL MUSCLES attached to the bone, so all the movements of hand and legs and whatever u do are because of voluntary muscles.

<h3><u>__________________________________________________</u></h3><h3><u>INVOLUNTARY MUSCLES:</u></h3>

the muscles in the human body that do not work under our will and we cant control them. They are mainly controlled by the autonomic nervous system in the body. So, involuntary muscles include all the muscles whose activity which is not controlled by our NERVES. They are also called SMOOTH MUSCLES since they are present as the visceral layer over the organs.

<h2>_____________________________________</h2><h2>DIFFERENCES</h2>

1)      VOLUNTARY MUSCLES are under our control but INVOLUNTARY                 MUSCLES are not under our control

2)      VOLUNTARY MUSCLES are also known as skeletal muscles but INVOLUNTARY MUSCLES are also known as smooth muscles

3)      VOLUNTARY MUSCLES are attached to the bones in the body, but INVOLUNTARY MUSCLES are attached to the soft hollow internal organs.

4)      VOLUNTARY MUSCLES are controlled by the somatic nervous system. INVOLUNTARY MUSCLES are controlled by the autonomic nervous system.

5)      VOLUNTARY MSUCLES  require more energy. INVOLUNTARY MUSCLES require less energy.

In a humoral or antibody-mediated immune response, specific B cells are stimulated by Helper T cells to help transform into plas
steposvetlana [31]

Answer:

An important feature that B-cells must have in order to become plasma cells and synthesize antibodies is increased rough endoplasmic reticulum in order to have the surface area needed for antibody production (option A).

Explanation:

The transformation of B cells into plasma cells to produce antibodies is a well known function of lymphocytes related to the immune response. This leads to a series of structural transformations in order to performs their function.

The rough endoplasmic reticulum (RER) has the function of contributing to protein synthesis, in conjunction with the ribosomes that are attached to it and the information of the mRNA.

<em>One of the changes experienced by B cells in their transition to plasma cells is the availability of larger RERs, in preparation for antibody synthesis, formed mostly by proteins</em>.
