Answer:During the second and third trimesters of
gestation androgenic C19 steroid, and dehydroepiandrosterone sulfate (DHEA-S), are secreted by the fetal adrenal gland and human placental lactogen (hPL), is secreted by the placenta.
Explanation:During midgestation, the fetal zone occupies 80–90% of the cortical volume and produces 100–200 mg/day of the androgenic C19 steroid, dehydroepiandrosterone sulfate (DHEA-S), which is quantitatively the principal steroid product of the primate fetal adrenal gland throughout gestation. While human placental lactogen (hPL) may be secreted preferentially into the fetal circulation, exerting growth-promoting effects at a time when the rate of linear growth of the fetus is maximal.
A scientific model is a claim or a theory that helps explain how a phenomenon works or how it undergoes process. This models provides scientists an understanding of the object or a situation undergoes change and generate certain outcomes or effects.
Well, many organisms would die. Plants need light so they would die out rather quickly. The surrounding area would warm up initially due to the green house effect, but would eventually cool down.
