Explanation:
Regarding the situation explained in the question that "African Americans are not affected by the malaria disease because of a specific genetic trait that they possess and that trait provides them with protection" can be explained by the answer given in option B.
Being heterozygous, meaning possessing a dominant and a recessive allele regarding that genetic trait, in terms of sickle cell trait which is a gene that causes the individual's blood cells to be sickle shaped and balanced polymorphism which means carrying two different versions of a gene is an argument that is enough to prove that the above statement is incorrect because it means they have blood cells that can be affected by the malaria disease.
I hope this answer helps.

Answer and Explanation:
An oil rig is a type of piston ring which is situated in the ring grooves. The oil ring is commonly used on small engines to wipe excess oil from the wall of the cylinder during the piston's movement. Through the opening of rings, excess oil returned to the oil reservoir. These rings are not used on the two-stroke cycle engines. These rings are one-piece or two-piece. An oil ring seals the combustion chamber through inherent pressure and controlling the consumption of oil. The inherent pressure of the oil ring is very high on the piston. These rings use an expander, high-pressure unit and inherent pressure. The oil rings are also used to spread the oil around the liner surface. These rings can be cut into various sizes. An oil ring has an axial.
Answer:
Each amino- acid contain carbon, hydrogen, nitrogen, and oxygen. All the amino- acids are mostly the same by structure because all contain a carbon atom in its center, an amine group, and a carboxyl group.
The unique characteristics that each amino acid has is determined by the R group(side chain) which is attached to its alpha carbon. The R group in each amino acid is different from others.
The simplest amino acid is glycine which does not have any R group so it has a hydrogen atom in place of the R group. So side chain(R group) determines the unique characteristics of each amino acid.
