Answer:
C. two tetramers of histone proteins
Explanation:
The nucleosome core particle is responsible for packaging DNA in the chromosomes. The protein components that make up the nucleosome core are two tetramers of histone proteins. One of which is composed of two units each of histones H2A and H2B, while the other one is composed of two units each of histones H3 and H4. Thus making up the entire protein component of the nucleosome core.
One example of stimulus is reacting to a hot pan. If you touch it, you immediately pull your fingers back. This is your nervous system sending alerts through your body, and to your muscular system. Your muscular system allows you to bend your arm, and move your fingers away from the hot pan.

<span>Ohm's law deals with the relation between
voltage and current in an ideal conductor. It states that: Potential difference
across a conductor is proportional to the current that pass through it. It is
expressed as V=IR. Therefore, the correct answer would be option 1. The current will increase as well since there is an increase in the voltage.</span>
<span>leukocytes would be the answer.
