No visible cytoplasmic granules are present in ________.
iVinArrow [24]

Hello, I figured your question was missing its answers so I went online to find them. Here they are:

No visible cytoplasmic granules are present in ________.

A) basophils

B) monocytes

C) eosinophils

D) neutrophils

Answer:

The correct answer is: B) monocytes.

Explanation:

<u>White blood cells can be divided into granular and agranular.</u> Granular leukocytes (WBC) have granules that contain enzymes in their cytoplasm (the enzymes are used in the immune and inflammatory responses). <u>Agranular leukocytes</u><u> do not have cytoplasmic granules</u>.

<u>The granular leukocytes are 3: basophils, eosinophils, and neutrophils</u>.

<u>The</u><u> agranular</u><u> leukocytes are: </u><u>monocytes</u><u> and lymphocytes</u>.

Monocytes are very large cells with the important function of phagocytosis: this makes them capable of eating pathogens and old blood cells. When arriving at a tissue outside of the blood, they differentiate to macrophages with special features to perform in that tissue. They make up <u>2 to 8 percent of all leukocytes</u>. Monocytes and macrophages are also antigen-presenting cells (APCs): when needed, they can present antigens to other white blood cells in order to mediate the immune response.

Which best describes the difference between osmosis and diffusion?
butalik [34]
<span>Correct answer: 
<span>Diffusion is the movement of particles from a high to low concentration, while osmosis is the movement of water from a high particle concentration to a low particle concentration.

</span></span><span>This movement of molecules occurs due to a thermal motion. Diffusion normally occurs between two compartments having difference in concentration. In case of fluid it moves from the region of higher concentration to the region of concentration until a balance is reached. The process of diffusion is very important for the humans as well. The oxygen that humans breathe in gets diffused with the blood.</span><span><span>
