Explanation:
Answer:
Because it is only possible to be 100% sure that two species are closely related, in genetic terms, when the DNAs of these species can be analyzed. This analysis is only possible through molecular tests.
Explanation:
Molecular tests are bikini techniques that can analyze species at the molecular level, more specifically, these tests can deeply analyze the DNA (or RNA and proteins) of a species giving precise results on the molecule and allowing scientists to study it deep.
In studies, where the scientist wants to know how the species are genetically related, it is common for molecular tests to be introduced, as a way for the scientist to be 100% sure of the relationship between the species.
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>
