The hypothalamus sends signals to the pituary glands. The hypothalamus releases dopamine, so I think dopamine is a good answer?
Human eye color is an example of a phenotype that results from the interaction of multiple gene products.
<h3>
Is eye color determined by genetics?</h3>
- A person’s eye color results from pigmentation of a structure called the iris, which surrounds the tiny black hole which is located in the center of the eye (the pupil) and helps control the intensity of the light that enters the eye.
- The color range of the iris is from very light blue to dark brown. Brown is that the most frequent eye color worldwide.
- Eye color is decided by variations in a person’s genes.
- Most of the genes related to eye color are involved in the production, transport, or storage of a pigment called melanin.
- Eye color is directly associated with the amount of melanin in the front layers of the iris. People with brown eyes have an outsized amount of melanin in the iris, while people with blue eyes have much less of this pigment.

Answer:
c
Explanation:
just give it a shot most answer are usually b and c
Answer:
Parentals: PP (purple) and pp (white)
F1: Pp (purple)
Explanation:
When the two parental plants of differing phenotypes (purple or white flowers) cross, the F1 is 100% purple. This result suggests that the parentals were true breeding (homozygous), with purple flowers being the dominant allele.
When the F1 self pollinates, the F2 shows proportions very similar to 3/4 purple and 1/4 white (401/532 ≅ 3/4 and 131/532 ≅ 1/4). The 3:1 phenotypic ratio is typical of the offspring resulting from a cross between two heterozygous individuals.
The results make sense if the genotypes of the different generations are:
Parentals: PP (purple) X pp (white)
F1: Pp (purple)
F2: 1/4 PP, 2/4 Pp, 1/4 pp
Answer:
The correct answer will be option-D
Explanation:
Pulmonary Surfactant is a complex substance produced by the pneumocytes epithelial II cells in the alveolar sac.
The surfactant is composed of the proteins and lipids which plays a role in keeping alveoli open by reducing the surface tension formed between the air and liquid.
The surfactant act by forming a monolayer surface film which helps reduce the surface tension.
Thus, option-D is the correct answer.
