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>
Is there a question i’m supposed to answer or is it just completely free?
The answer should be D, because it’s always good to provide statistics
A riparian buffer is usually a piece of land along a water course, where no farming is allowed with the purpose of protecting the water course.
A riparian buffer is important for protection of water quality. Riparian zones help sediments, phosphorous, nitrogen, pesticides and other pollutants from reaching a river or stream.
The root system of plants, shrubs and trees growing on the riparian buffer land stabilize the soil, and thus prevent sediments and pollutants from entering the water body .
