Answer:
F (pp) = 0.04
F (Pp) = 0.32
F (PP) = 0.64
Explanation:
Studying population genetics, we used the Hardy-Weinberg equilibrium model. In the case of snails, the H-W principle predicts that the total number of cases in the population should follow the following equation: PP + 2.Pp + pp = 200.
If a population has 200 snails and 8 are affected by a recessive condition, we have 4% affected, or 0.04.
This means that 0.04 corresponds to p², and p corresponds to 0.2.
Therefore, P is equal to 0.8 because p + P = 1.
Knowing the allele frequencies, we go to the frequency of the genotypes.
F (pp) = p² = 0.04 = 8 snails
F (Pp) = 2.Pp = 0.32 = 64 snails
F (PP) = P² = 0.64 = 128 snails
Answer: c. regulates the secretory activity of the pituitary gland.
Explanation:
The hypothalamus can be defined as a small part of the brain that is located at the base of the brain. It has two functions in the human body, first releasing hormones and maintaining homeostasis.
The hypothalamus is responsible for linking the endocrine system to the brain through the pituitary gland. It stimulates the secretion and inhibition of the hormones from the anterior pituitary.
Answer;
X, Z, Y, W
Explanation;
-Kinetic energy is the energy an object has due to its motion. As long as an object is moving at the same velocity, it will maintain the same kinetic energy.
-The kinetic energy of an object is calculated from the velocity and the mass of the object. K.E =1/2 mv²
-From the formula the velocity is squared which means it can have a significant impact on kinetic energy, thus the higher the velocity the higher the kinetic energy. The kinetic energy is also impacted by the mass of a body, such that the higher the mass the higher the kinetic energy.
