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.
This might be a case of high velocity blood spatter. This type of blood stain is most likely to be caused by a gun of a small calibre. The gunshot usually causes high velocity blood spatter or can be caused by other objects when high amount of force is exerted. The high velocity blood spatter are caused by force travelling at a speed of 100 feet per second or more which produces droplets of diameter less than 1 mm. Explosions may also cause such high velocity blood spatter.
The umbilical region, in the anatomists' abdominal pelvic nine-region scheme, is the area surrounding the umbilicus and it is placed approximately on middle of distance between xiphoid process and pubic symphysis (navel).
B.cell wall
Cellulose is an important structural component of the primary cell wall of green plants.
