Answer:
d. cerebrum, cerebellum, and brain stem is the correct answer.
Explanation:
The three major parts of the brain are:
- Cerebrum: It the largest part of the brain. It is made up of the right hemispheres and left hemispheres. It is responsible for voluntary activity, sensory functions, and neural functions.
- Cerebellum: It the region found below the cerebrum and back the brainstem, the function of the cerebellum is to regulate the motor and voluntary movements.
- brainstem: It controls the basic function of the body such as heart rate, breathing, blood pressure, swallowing, and consciousness.
Body chemicals that regulate sleep, moods, hunger, and stress are called hormones
<u>Explanation:</u>
These hormones are a type of proteins that are secreted in the body as in response to various activities that happen in a body. They do not have a separate pathway system they just flow along with the blood.
They serve as a communication tool between tissues. The glands which secrete these proteins are termed as endocrine glands. If these hormones affect the same cell they are called as autocrine and different cells are called as exocrine.
Auxin is the molecule which is related to the phototropism of the plants. In the mutant plants, which do not have hormone auxin, do not respond to light. It activates proton pump, and leads to the decrease in the pH of the leaf. This acidification breaks cell wall structure and cell wall become less rigid, and thus, can bend towards the light, by exerting mechanical pressure.
They both transport ions, sugars, and salts across the membrane
