7 0

Answer:

The correct answer is D a change to one amino acid in a protein may cause a significant change in the phenotype.

Explanation:

Sickle cell anemia is caused by the replacement of 6th amino acid in the beta chain of hemoglobin that is glutamic acid by valine.

   glutamic acid is a hydrophilic amino acid that is being replaced by a hydrophobic amino acid known as valine.

   As a result the red blood cells  appear as insoluble aggregates which which ultimately result in the sickling of Red blood cells.That"s why this disease is named as sickle cell anemia.

polet [3.4K]

Similarity

Both nervous and endocrine system are similar in a way that they perform the regulatory function in the body and act as regulator in various body functions.

2. The nervous system can respond quickly to stimuli, through the use of action potentials and neurotransmitters. Responses to nervous system stimulation are typically quick but short lived. The endocrine system responds to stimulation by secreting hormones into the circulatory system that travel to the target tissue.
