Answer:

midbrain, medulla, and pons

Explanation:

The brainstem (also known as truncus encephali) is localized in the posterior part of the brain, in the base between cerebral hemispheres and the cervical cord. <em>It's divided into three parts, the midbrain or mesencephalon, the pons or mesencephalon, and the medulla oblongata also known as long medulla or myelencephalon.</em> <em>In the image I added you can see the brainstem structure.</em>

Some of the brainstem functions include the regulation of respiratory and cardiac function, thermoregulation, and other functions related to vision, sleep, etc.

Alik [6]

Hi! :)

Make a = q, aa (homozygous recessive) = q^2,
A = p, AA (homozygous dominant) = p^2, and
2pq = heterozygous
This was derived from p + q = 1
Therefore all a in pop (q) = 20% = .20

And all A in pop (p) = 80% = .80
Since the disease is homozygous recessive (affected), then aa = qq or q×q = q^2
q^2 = (.20)^2 = .040 = 4%

Answer: 4%
