Answer:
Mechanical digestion begins in the mouth as the food is chewed. Chemical digestion involves breaking down the food into simpler nutrients that can be used by the cells.
Explanation:
Chemical digestion begins in the mouth when food mixes with saliva. Saliva contains an enzyme (amylase) that begins the breakdown of carbohydrates.
Answer:
No the atomic mass is the same as the atomic number
Explanation:
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.
Answer:
Glass
Explanation:
Copper is a good conductor of electricity and this is why it is used in electrical equipment to transmit electrons with the least resistance. Cable conductors are made of copper and used to transmit data. Copper is now being replaced by optic fiber that is made of glass. Instead of using electrons, fiber optic transmits data using photons – which transmits more data rate than copper.
