Sickle cell is a disorder that affects the
molecules in the red blood cells, particularly the hemoglobin. The hemoglobin
is the molecule responsible for transporting oxygen throughout the body. When a
person has sickle cell anemia, the red blood cells are distorted crescent
shapes that do not travel in the bloodstream properly and efficiently. As a
result, this disorder hampers the distribution of oxygen throughout the body.

Anemia is the major characteristic of sickle cell
disorder. A person with sickle cell anemia has low number of red blood cells
that usually begin in early childhood. A person who is experiencing Sickle Cell
Anemia will have multiple and repeated infections, and periodic episodes of
pain. The severity of this condition varies from person to person but is common
in African descents. </span>
Answer:
two (a pair)
Explanation:
Centrioles are the pair of hollow cylinders that are located near the nucleus in the cytoplasm in a non-dividing cell. Two centrioles together make a centrosome. Centriole duplication occurs before cell division as the duplicated centrioles take part in the formation of the spindle apparatus. However, cytokinesis distributes one pair of centrioles to each daughter cell. Therefore, after cytokinesis, two centrioles are present in each daughter cell.
The process used to describe the process by which two separate species may evolve in a similar way is called Natural Evolution
Fibrosis patient may suffer from the blood clotting when exposed to air
c- the blood clotting when exposed to air
<u>Explanation:</u>
Fibrosis is the development of excess fibrous connective tissue in an organ or in a reparative or responsive procedure. It is a sort of interstitial lung illness. It is brought about by lung tissue getting thick and solid and in the long run framing scar tissue inside the lungs.
Platelets ordinarily start the thickening procedure when they'reexposed to the air, for example, in a cut or wound. Blood clumps structure when certain pieces of your blood thicken, shaping a semisolid mass. This procedure might be activated by damage or it can here and there happen inside veins that don't have conspicuous damage.
In people, cell parts make up roughly 45 percent of the blood and the fluid plasma 55 percent. Be that as it may, some of the time blood clumps structure too effectively or doesn't break down appropriately and travel through the body restricting or blocking bloodstream. This is called over the top blood thickening or hypercoagulation and can be perilous and prompts Fibrosis.
