Answer:
Heterozygous
Explanation:
An organism in which the two copies of the gene are identical — that is, have the same allele — is called homozygous for that gene. An organism which has two different alleles of the gene is called heterozygous. Pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white). Carriers are always heterozygous.
I will go with A ....as radiation is out of question..... DNA sequence is same in all.......I don't think evolution is a mistake !
so A
I believe you are referring to the full case study which says :
"<em>Your goal is to stop Clark's seizures by restoring equilibrium between the blood and the matrix. Based on the data collected and what you have learned about osmosis and the three treatment options, rank the treatments from most effective to least effective. What do you predict?</em>"
Although I could not locate the options in order to provide a ranking, I can offer the insight that a hypertonic saline solution will be the most effective form of treatment.
A hypertonic saline solution is used to draw water out of cells by creating an increased concentration of solute in the blood, forcing the water out of the cell through osmosis.
Clark's seizures may be caused by Increased solute concentrations in the brain which forces water from blood to move into the brain, thus increasing the matrix pressure. This then causes the neurons to fire at an increased rate and leads to the seizures Clark was experiencing.
Hypertonic saline can be used to increase solute concentrations, in this case, Sodium, in the blood which forces water to move back into veins. Thus returning Clark to a balanced level of blood and matrix water levels, and may reduce his likelihood of seizures.

The cause of hyperpolarization of a neuronal membrane is the flow of positive ions out of the opening channel of the neuronal membrane.
What is hyperpolarization?
This can be defined as when the membrane potential becomes more negative at a particular spot on the neuron’s membrane.
The cause of hyperpolarization is when the flow positive ions out of the opening channel of the neuronal membrane can cause hyperpolarization.
Examples: Opening of channels that lets K+ flows out of the neuronal membrane or let's CL- flow into the neuronal membrane can cause hyperpolarization.
