What is the effect of sickle-cell anemia?
belka [17]

Answer: Option C.

Inefficient oxygen transportation.

Explanation:

Sickle cell anaemia is an inheritable condition in which the red blood cells cannot carry oxygen to the organs or whole body because the red blood cells shape has been distorted and is sickle in shape. In this condition there is not enough red blood cells to carry oxygen in the blood.

What animals did the grant study in galapagos island?

Galapagos finches did the grant study in Galapagos island.

Galapagos finches is a piece of evidence supporting the theory of evolution.

Darwin's finches comprise a group of 15 species endemic to the Galápagos (14 species) and Cocos (1 species) Islands in the Pacific Ocean. The group is monophyletic and originated from an ancestral species that reached the Galápagos Archipelago from Central or South America.

What did he observe?

During the survey voyage of HMS Beagle, Darwin was unaware of the significance of the birds of the Galapagos. He had learned how to preserve bird specimen while at the University of Edinbugh and and had been keen on shooting, but he had no expert in ornithology and by this stage of the voyage concentrated mainly on geology. Nonetheless, these birds were to play an important part in the inception of Darwin’s theory of evolution by natural selection.

What was the brief goal of their studies?

All of Darwin's observations and insights, plus reading of increasing population growth and demand for limited resources, brought him to his theory of natural selection. Briefly, this means that individuals better adapted to their environment survive and increase in number through reproduction.

What did they conclude?

Conclusion:

Charles Darwin deserves primary credit for the theory of evolution. He developed existing ideas about descent with modification while providing a large body of evidence in support of them, and he was the first person to perceive thatnatural selection is the primary force behind evolution.
