Answer: A-T or G-C

Explanation:

The single-nucleotide polymorphism in human genomes is a substitution of a single nucleotide which occur in a specific position at the genome. The A-T nucleotide may appear dominant in the most population, while the remaining minor population may have the G-C nucleotide. The DNA molecule in the population at this site have A-T or G-C.

Other than to determine evolutionary relationships, what are molecular clocks used for?
ra1l [238]

Given what we know, we can confirm that molecular clocks are also used to help classify organisms.

<h3>Why are they used to classify organisms?</h3>

Molecular clocks can be used to help classify organisms by providing a context for the development of that organism. That is, they allow us to see the genetic history of evolution into that organism and to know to which organisms it is most closely related.

Therefore, we can confirm that molecular clocks are also used to help classify organisms.

Explain the difference between sex hormones and glandular stimulating hormones
bagirrra123 [75]

Answer:

Sex hormones are those hormones that within the endocrine system of the human being, are considered more directly involved in human sexuality, particularly in the processes of copulation and reproduction.On the other hand, glandular stimulating hormones are those that act on hormonal production in another endocrine gland, that is, they are stimulants, since they stimulate the corresponding glands.

Explanation:

Sex hormones are chemical substances secreted by the sex endocrine glands (the testes and ovaries) and subsequently released into the bloodstream, to be transported to the organs on which they exert their action (increasing or decreasing their activity).The production of hormones is regulated in many cases by a negative feedback system, which causes an excess of a hormone to be followed by a decrease in its production. The glandular stimulating hormones are transported to the blood to stimulate the corresponding glands (thyroid, adrenal cortex, and gonads) and these will be the ones that secrete various types of hormones (thyroxine, corticosteroids and sex hormones, respectively), which in addition to acting in the body, they feed back into the pituitary and hypothalamus to inhibit their activity and balance the respective secretions of these two organs and the target gland. For example, follicle-stimulating hormone encourages sperm production in men and stimulates the ovaries to release eggs in women. Luteinizing hormone and follicle stimulator work together to allow normal function of the ovaries or testicles.
