The brain stem consists of the ________. The brain stem consists of the ________. cerebrum, pons, midbrain, and medulla midbrain
, medulla, and pons pons, medulla, cerebellum, and midbrain midbrain only
1 answer:
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.

Answer:
Explanation:
It is given that
B is the dominant allele which represents the black color
and b is the recessive allele which represents the white fur.
B being dominant will result into black color fur for genotype "Bb"
Given -
Frequency of black fur allele (p) is
As per Hardy Weinberg's first law of equilibrium
Substituting the value of p in above equation, we get -
q represents the frequency for white fur allele
Frequency of white fur phenotype is
Frequency of homozygous black fur phenotype (BB) is
As per Hardy Weinberg's second law of equilibrium -
Combined frequency of homozygous and heterozygous black fur phenotype is
