Ugo [173]

Answer:

The correct answer will be- red blood cells (RBC)

Explanation:

Malaria has proved endemic to the human species as it has killed the humans in large numbers and it has acted as one of the strongest selective force.

The malaria disease has caused the mutation in the genes in the red blood cells which carries the oxygen to different organs of the body. The mutation in the genes causes the circular shape of red blood cell to sickle-shaped cells which carry less oxygen to the organs.

The change in the shape of red blood cell provides resistance against malaria disease but it becomes a problem where malaria is not a problem.

Thus, red blood cells (RBC) is the correct answer.

com base no que aprendeu neste capítulo, explique como seriam gerados trigêmeos univitelinos e trivitelinos?
Liono4ka [1.6K]

Answer:

Um único nascimento é formado quando um óvulo produzido por uma fêmea é fertilizado por um espermatozóide e forma um zigoto que cresce para formar um embrião que cresce para se tornar uma criança. Os trigêmeos, no entanto, podem ser formados quando um óvulo é fertilizado pelo esperma (zigoto) e se divide em três, resultando em trigêmeos idênticos ou se um dos dois óvulos fertilizados se divide em dois, resultando em duas crianças idênticas e uma não idêntica.

Explanation:

No caso dos trigêmeos, eles podem ser idênticos (fraternos) ou não idênticos (uma mistura de crianças fraternas e não idênticas), do mesmo sexo ou não do mesmo sexo.
