Answer: depolarization; hyperpolarization
Explanation:
At resting potential (absence of stimulus), the cell membrane of a neuron is said to be polarized with a net negative charge within due to more potassium (K+) ions present than sodium (Na+) ions.
However, an impressed stimuli reverses the ions content as K+ ions flows out and quickly replaced by Na+ ions, resulting in a decrease in membrane potential and a more positive cell membrane. Thus, depolarization occurs.
An increase in the membrane potential (so that it becomes more negative) is called hyperpolarization.
Answer is: when the carbon atoms of the glucose molecule are broken apart in glycolysis and the Krebs cycle, result is a. CO2 and ATP.
In Krebs cycle aerobic organisms release stored energy through the oxidation of acetyl-CoA derived from glucose into carbon dioxide and chemical energy in the form of adenosine triphosphate (ATP).

A=T= 40%....so together this is 80% of the DNA.
That leaves 20% to be C+G...so each is 10%. A is the answer.
