During the second and third trimesters of
Verizon [17]

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.

jekas [21]

Answer:

Claim 5: Cells need glucose AND oxygen to release energy.

Explanation:

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage through the breathing of oxygen used to obtain energy from the food ingested.

Hence, cells need glucose and oxygen to release energy.
