Answer:
melatonin
Explanation:
Oxytocin is called a peptide hormone and is normally produced in the hypothalamus, it's released by the posterior pituitary gland. It usually plays a role in social bonding, reproduction, childbirth, and the period after childbirth.
Serotonin is a monoamine neurotransmitter. It plays a vital role in feelings of well-being and happiness. it helps in mental cognition, reward, learning, memory, and numerous physiological processes.
The prostaglandins are groups of physiologically active lipid compounds called eicosanoids having diverse hormone-like effects in animals. It participate in a wide range of body functions such as the contraction and relaxation of smooth muscle, the dilation and constriction of blood vessels, control of blood pressure etc.
Melatonin is a hormone that regulates the sleep–wake cycle. It is primarily released by the pineal gland. As a supplement, it is often used for the short-term treatment of trouble sleeping.
Definitely, if the sleep scientist is working on developing a drug for people who lack proper amount of sleep hormone, He should be working on Melatonin.
Answer:
15.21 %
Explanation:
If we recall the basic formula of Hardy-Weinberg's equilibrium ; we have the following below:
p + q = 1
p² + 2pq + q² = 1
where;
p = frequency of the dominant allele in the population
q = frequency of the recessive allele in the population
p² = percentage of homozygous dominant individuals
q² = percentage of homozygous recessive individuals
2pq = percentage of heterozygous individuals
Given that p= 0.68 and q = 0.39
the percentage of the homozygous recessive genotype (q² ) will be
(0.39)² = 0.1521
= 0.1521 × 100
= 15.21 %
∴ the percentage of the population that has a homozygous recessive genotype = 15.21 %
The answer is x-linked recessive. It is apparent that the color blindness affects the males hence it's caused by a sex-linked recessive gene. Males have XY homologous chromosomes. The X sister chromosome has more genes than the Y sister chromosome, hence most males are hemizygous for sex linked genes. This means that even recessive genes on the X chromosome are likely to be expressed in males.

Answer:
Breathing Is Automatic and Not Autonomic
Conscious factors can override or modify automatic functions of the respiratory control system for a limited period. For example, an individual can voluntarily speak, smell, hyperventilate, or hold their breath.
