Answer:
natural selection is natural, selective breeding is not. Natural selection is when the best genes are passed down. Selective is when the best of an animal group are forced to mate
Explanation:
The Miller-Urey experiment showed that simple molecules could have arisen abiotically. This chemical experiment included conditions similar to those present on the early Earth, and tested the origin of life under those conditions.
Water (H2O), methane (CH4), ammonia (NH3) and hydrogen (H2) were the chemicals used to produce the results of the experiment, the factors needed for simple life to arise. Given similar conditions on other planets, it's possible that life could arise there as well.
Answer:
If a child has an autosomal dominant trait, then at least one parent has the autosomal dominant trait. If both parents have an autosomal dominant trait, then all of their children will have that trait. If both parents have an autosomal recessive trait, then all of their children will have that trait.

Description:
Therapeutic Progesterone is a synthetic form of the endogenous hormone progesterone. Progesterone binds to the progesterone receptor, resulting in dissociation of heat shock proteins, receptor phosphorylation, and transcription activation through direct or indirect interaction with transcription factors. This agent exerts inhibitory effects on estrogens by decreasing the number of estrogen receptors and increasing its metabolism to inactive metabolites. Progesterone induces secretory changes in the endometrium, decreases uterine contractility during pregnancy, and maintains pregnancy. (NCI04)

Progesterone is a Progesterone. The chemical classification of progesterone is Progesterone.
from FDA Pharm Classes
Progesterone is a C21-steroid hormone in which a pregnane skeleton carries oxo substituents at positions 3 and 20 and is unsaturated at C(4)-C(5). As a hormone, it is involved in the female menstrual cycle, pregnancy and embryogenesis of humans and other species. It has a role as a contraceptive drug, a progestin, a progesterone receptor agonist, a human metabolite and a mouse metabolite. It is a 20-oxo steroid, a 3-oxo-Delta(4) steroid and a C21-steroid hormone. It derives from a hydride of a pregnane.
