I think the correct answer would be the last option. People with one sickle cell allele are not likely to get malaria. This would be an example of genetic drift. It is one of the mechanism of evolution which involves the change in the frequency of an allele in a certain population due to the random sampling of the organisms. It is when a certain trait is being spread by chance rather by natural selection. Sickle cell is classified as an autosomal recessive disease that is caused by hemoglobin. It is a disease that is inherited depending on how the alleles are received. So, it can be inherited by chance.

The sun rotates faster on the equator describes the motion of the sun.

<h3><u>Explanation:</u></h3>

The rotation of sun differs at varying rates. The rotation of the sun will not be constant. The sun  rotates once in 25 days near the equator. When the latitude increases, the rotation of the sun decreases. Thus, the rotation of the sun will be slower when it approaches the poles. Sun rotates once in 35 days near the poles.

This motion of the sun near the equator where it is fast makes it to be a complete  sphere. This is known as differential rotation. In the statements given, the motion of the sun is clearly described by the sun rotates faster on the equator. Sun rotates slowly near the poles.
