Which person’s function in a school is similar to the central nervous system’s role in a human body?
Alekssandra [29.7K]

Explanation:

options...

-a cafeteria worker

-a student

-a principal

-a bus driver

<u>correct: -a principal </u>

Further explanation:

The model places the principal as the brain or control center, where it regulates all activities related to homeostasis, just like a school.Cells sharing a similar origin, group together in the body to form tissues; these typically share physical features and are arranged in regular patterns. They are interdependent, and work together like members of a school, as tissue.

The nervous system is subdivided into; the central nervous system (CNS), which includes the brain and spinal cord, within the vertebral column; and the peripheral nervous system, which includes nerves that branch into the rest of the body from the brain and spinal cord. Nervous tissue responds to electrical impulses, allowing for communication between different regions of the body.

The peripheral nervous system is further divided into the somatic nervous system responsible for carrying out sensory and motor information between the peripheral nervous system- including sensory organs like the eyes; and central nervous system; and the autonomic nervous system (ANS) which regulates involuntary bodily functions like heartbeat, breathing and blood flow. The ANS is mainly acts unconsciously and affects smooth muscle and internal organs. It is related to homeostasis- where the body maintains a constant internal balance in pH, temperature, blood pressure etc.

Katen [24]

Answer:

The correct answer is : temporal isolation.

Explanation:

Temporal isolation is a one type of prezygotic reproductive isolation in which the the prevention of mating of the two species takes place due to the time difference of breeding, this could be day difference, season difference,  or years difference.

Here in this example the reproductive isolation is taking place due to the difference in their mating time, where L. graminifolia flowers in the early spring and L. canadensis in different season of summer.

Thus, the correct answer is : temporal isolation.
