Answer:
- <u>Option:(1)-</u>The <u>Genetic drift </u>theory is an evolutionary concept that suggests that behaviors that help an organism survive are passed on while weak behaviors are lost.
Explanation:
According to this theory, an organisms faces different levels or kinds of environmental factors, which either suppresses or increases the level of a certain allele frequency inside an organisms genetic sequence, which then results in the change in behavior of that organism. And through many generations the changes in behavior may pass on from one to another, as the changes does not occur in a single generation.But, the alleles frequency are suppressed and increased with time, when they face different environmental factors or situations.
Osteoporosis is the disease of the low bone mass and most often caused by the increase in the bone resorption that is not in sufficiently compensated for by the corresponding increase in the bone formation. As result gut-derived serotonin (GDS) inhibits the bone formation, we can asked whether hampering its is biosynthesis that could treat the osteoporosis through the anabolic mechanism (that is, by increasing bone formation).
We can synthesized and used the LP533401, a small of molecule inhibitor of the tryptophan hydroxylase-1 (Tph-1), the initial enzyme in the GDS biosynthesis. or the Oral administration of this small molecule once daily for up to the six weeks that acts as prophylactically or therapeutically, in the dose-dependent manner, to treat the osteoporosis in the ovariectomized the rodents because of an isolated increase in the bone formation. These results that provide a proof of the principle that have inhibiting the GDS biosynthesis that could become a new anabolic and treatment for osteoporosis.

Answer:
Cl- ions will move inside the cell.
Explanation:
When the equilibrium potential and is equal to membrane potential, the net charge across the membrane is equal to zero and therefore there is not movement of ions across the membrane. However, in this case, the membrane potential is -70 mV, while the equilibrium of negatively charged Cl- ions is -81 mV. In consequence, Cl- ions will tend to move inside of the cell.
<h2>Nutrient density</h2>
Explanation:
- Nutrition is molecules in food that all living beings need to cause vitality, to develop, create, and recreate. Supplements are processed and afterward separated into fundamental parts to be utilized by the creature. There are two fundamental kinds of supplements, macronutrients, and micronutrients. The three fundamental classes of macronutrients incorporate sugar, protein, and fat. The two kinds of micronutrients are nutrients and minerals, and these are additional particles that cells need to make vitality.
- "Nutrient density" signifies the amount you get of a certain something, given the nearness of something different. On account of nutrient density, the "things" you get, the supplements, are dissected in relationship to the amount they "cost" you, regarding calories. Essentially expressed, nutrient density implies what number of supplements you get from nourishment, given the quantity of calories it contains. nutrient density is a simple method to associate supplements with calories. No nourishments are more supplement thick than entire, naturally developed food sources.
