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.

Explanation:
You are testing the affects of different soils on the germination of seeds, therefore, you must compare different types of soil. The other answers don't have correlation to different types of soils, and are incorrect.

Explanation:
Tidal volume (TV) is the volume of oxygen that enters the lungs (inspiration) through normal breathing. It is measured per kg of body mass.
It is also measurement applied by a ventilator machine. The machine delivers oxygen and the amount delivered is calculated as tidal volume.
'Remaining in the lungs after forced expiration' is called Inspiratory Reserve Volume (IRV)
'Forcibly expelled after normal expiration' is called Expiratory Reserve Volume (ERV)
