Human chorionic gonadotropin (HCG) is secreted from the placenta.

  • During pregnancy, the placenta's syncytiotrophoblastic cells largely generate the hormone human chorionic gonadotropin.
  • To keep the pregnancy going, the hormone stimulates the corpus luteum to release progesterone.
  • Along with the pituitary, the liver, and the colon, other organs that produce less HCG include the colon.
  • The two subunits of HCG are HCG alpha and HCG beta .
  • HCG injections are frequently used to promote ovulation in assisted reproductive treatments because they boost progesterone production in the corpus luteum during the early stages of pregnancy.
  • It signals the body to stop menstruating and thickens the uterine lining to support a developing embryo.
  • After fertilization, HCG levels increase and stay elevated for another 10 weeks or more of pregnancy.

Describe a scenario in which a scientist might use both relative and absolute methods of dating.
Arturiano [62]

IN ORDER TO PREDICT THE AGES AND HISTORY OF GEOLOGICAL SPECIMENS SCIENTIST USE BOTH RELATIVE AND ABSOLUTE METHODS OF DATING.

Explanation:

Our planet inherited large number of ARTIFACTS AND MONUMENTS  that are unearthed from older historic civilizations, to determine their ages and history relative dating and absolute dating methods are used. Although both dating dating methods are used to determine age and history the results produced by the two methods are different. Absolute dating also called numerical dating determines age and the relative dating presents in geological order formation.

For scientists when they find ruins of once civilization or layers of fossils or rocks. By looking at these using relative dating method they determine how younger/older is a particular object with respect to other and also this method is qualitative and effective in terms of radio active isotope or radio carbon dating. Absolute dating is time consuming compared to relative dating, it is quantitative. Absolute dating is better for igneous and metamorphic rocks.

ehidna [41]

Theory of natural selection by Charles Darwin explains the moth appearance in England. The theory of genetics describes this as a mere shift of trait due to environmental factors.

<h3><u>Explanation:</u></h3>

Peppered moths are the moths found in England from a long time ago. The environment before the industrial revolution was pure and pollution free, which led to the growth of the white variety of moths as they were able to camouflage better with the bark of the trees from their hunters. The white trait were the parents, and fertilization between the two recessive traits gave rise to the recessive traits only.

But with the industrial revolution, the pollution increased to a huge extent, leading to deposition of smokes and soot on trees bark where white variety of the white moths got easily recognizable. This led to the black moths which now can camouflage better. Thus the nature selected black variety over white variety for better survival, and the white variety reduced dramatically.
