Hello, I figured your question was missing its options so I went online to find them. Here they are:
The process of phagocytosis involves all of the following EXCEPT
:
a. adhesion.
b. secretion of cytotoxins.
c. elimination.
d. vesicle fusion.
e. chemotaxis.
Answer:
The correct answer is: b) secretion of cytotoxins.
Explanation:
Phagocytosis is a mechanism performed by cells in which the plasma membrane engulfs a large particle. Phagocytosis is used by cells in the immune system to ingest pathogens like viruses and bacteria.
Phagocytosis consists of many steps:
- activation
- the phagocytes that were resting are activated in the inflammatory response when a pathogen enters the body.
- chemotaxis - this refers to the process in which the phagocyte moves to the pathogen by following the chemical factors released by these germs.
- adhesion - the phagocyte attaches to the pathogen.
- ingestion
/vesicle fusion - the phagocyte sends pseudopods to engulf the pathogen, and places it in a phagosome, which is an endocytic vesicle. The phagosome and the phagocyte will fuse so the pathogen gets inside.
- elimination - the pathogen is destroyed in the phagocyte by the lysosomes present in it.
<u>The</u><u> secretion of cytotoxins</u><u> is not a part of the phagocytosis, and is a process exclusive to </u><u>T cells</u><u> (leukocytes that lack the ability to phagocyte).</u>
Answer:
It is due to the temperature of the star
Explanation:
The colour of star depends on the temperature of star.
Answer: During mitosis a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells.
Explanation:
Answer:
Bilirubin.
Explanation:
Bilirubin may be defined as the yellow color pigment that occurs during the normal catabolic pathway of humans.This process in important for the removal of harmful waste products from the body.
Bilirubin is excreted in urine and bile. Jaundice causes the deposition of bilirubin that makes the body color yellow in the disease. The body's harmful waste are not eliminated due to the excess deposition of bilirubin in the body.
Thus, the answer is bilirubin.
