Scientists are researching sickle cell anemia. Sickle cell anemia is a type of blood disorder which causes a sickle shape of red
blood cells and causes an abnormal shape of a protein that is used to carry oxygen. They wonder how a mutation of DNA can cause sickle cell anemia. Which statement best supports the claim that a mutation of DNA can cause sickle cell anemia? O A. Offspring inherit a normal copy of DNA from parents. OB. A change in the sequence of DNA cause different genes to be expressed. O C. All cells contain genetic information that produces the same types of proteins. D. DNA of an organism provides the directions for the production of red blood cells.
. The main structural differences between plant and animal cells are the additional structures found in plant cells. These structures include: chloroplasts, the cell wall, and vacuoles. In animal cells, the mitochondria produces the majority of the cells energy from food.
