Most Archaeans lack a ______ cell wall.

Biology
1 answer:
Morgarella [4.7K]3 years ago
6 0
Most Archaens lack peptidoglycan<em> </em>a.k.a murein in their cell wall. Peptidoglycans help maintain the strength of the cell wall as well as repel the osmotic pressure in the cytoplasm. A common misconception of the use of peptidoglycans is that it gives the cell shape. However, peptidoglycans only improve the structure of the cell wall by strengthening it.

Studies suggest that the incidence of colon cancer may be lowered with high fiber diets. how might this be explained?
Triss [41]

The increase in the high fiber diet reduces the risk of colon cancer is suggested by the researchers. The effect of high fiber dietary intake add bulk to the digestive system. It also reduces the time required by the food to travel from the colon. Our food often contains some carcinogenic contents, so the interaction of such carcinogens may also be reduced due to the high fiber diet and also reduces the risk of intestinal tract. The bacteria in the lower intestine breaks the fibers into butyrate, which inhibits the growth of tumors of the colon and rectum.

Sickle Cell anemia is a disease caused by a recessive allele. What is the chance a child will have Sickle Cell if one parent has
zlopas [31]

If one parent has been affected by sickle cell anemia, while the other parent does not and is homozygous, the chances that a child will have this disorder is 0%. Thus, the correct option is C.

<h3>What is Sickle Cell anemia?</h3>

Sickle Cell anemia may be defined as a genetic disorder that is caused by a recessive allele. It is an inherited disease in which the red blood cells have an irregular crescent shape, obstruct small blood vessels, etc.

This disease is inherited when both genes of each parent are supposed to be defective or carriers. While in this case, only parents are affected by the disorder while the other is homozygous for the normal allele.

In this condition, all the offspring produced by both parents remain as carriers but not affected ones.

Thus, the correct option is C.
