Imagine that you are talking with one of your friends about your biology course. he states that the somatic nervous system is subdivided into sympathetic and parasympathetic components, and is responsible for involuntary responses. is this statement correct?
a) no, although the somatic nervous system controls involuntary responses, it is the autonomic nervous system that is subdivided into parasympathetic and sympathetic components.
b) no, although the somatic nervous system does have both sympathetic and parasympathetic subdivisions, it is responsible for voluntary responses.
c) yes, this statement is correct. the somatic nervous system has both sympathetic and parasympathetic components and controls involuntary responses.
d) no, the somatic nervous system is responsible for voluntary responses, and is not subdivided into sympathetic and parasympathetic components.

The correct answer is option d) "No, the somatic nervous system is responsible for voluntary responses, and is not subdivided into sympathetic and parasympathetic components".

Explanation:

The somatic nervous system is responsible for the control of voluntary body movements via skeletal muscles. Also, the somatic nervous system is not subdivided into sympathetic and parasympathetic components. This subdivision corresponds to the autonomic nervous system, the system that influences the function of internal organs. Therefore the statement of the friend was incorrect.

humans, along with other animals and plants, have linear chromosomes that are arranged in pairs within the nucleus of the cell. the only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome.

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.
