Genetic variation is a prerequisite for evolution because natural selection relies upon lessening the frequency of alleles in a population therefore there must be variance in the gene pool
Answer:
During one cycle, two carbon molecules, three NADH molecules, one FADH2 molecule, and one ATP or GTP molecule are produced. Each glucose molecule produces two acetyl CoA molecules, enough for two cycles
The relationship is modeled by the equation y = 7.7079x - 7.
Here, y is the dependent variable which is the Earth Mass, and x is the independent variable which is the Earth Radius.
Solving for the Earth Mass if Earth Radius is 3.2 (x=3.2), we substitute 3.2 to x.
7.7079(3.2)-7
=7.7079 times 3.2 -7
=24.66528-7
=17.66528
7.7079(3.2)-7=17.66528
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.
Answer:
The answer is B. A book sitting on a high shelf.
Explanation:
Because the book is balanced, and something that is balanced stays balanced until you move it.
