As a result of the non-selectivity of the kidney's filtration of small molecules, _____. see concept 44.4 (page 986)
kondor19780726 [428]
As a result of the non-selectivity of kidney's filtration of small molecules, useful substances must be selectively reabsorbed to the blood.  Filtration is the mass movement of water and solutes from plasma to the renal tubule that occurs in the renal corpuscle. About 20% of the plasma volume passing through the glomerulus at any given time is filtered. Glomerulus lets fluid and waste products pass through it, however, it prevents blood cells and large molecules, mostly proteins, from passing.

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.
