B. genetic variation imparting reproductive success.
Rules for naming plants and animals are found in the International Code of Nomenclature.
Answer: C) or the third option.
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.
Starch and cellulose are two very similar polymers. In fact, they are both made from the same monomer, glucose, and have the same glucose-based repeat units. There is only one difference. In starch, all the glucose repeat units are oriented in the same direction..
