After fertilization, the successful development of a mature, full-term fetus depends on A. The release of human chorionic gonadotropin (hCG) by the developing placenta AND the production of estrogen and progesterone by the placental tissues B. the release of human chorionic gonadotropin (hCG) by the developing placenta C. maintenance of the corpus luteum for all 9 months D. all of these E. the production of estrogen and progesterone by the placental tissues
Answer:
The correct option is A (The release of human chorionic gonadotropin (hCG) by the developing placenta AND the production of estrogen and progesterone by the placental tissues).
Explanation:
The developing placenta release Human chorionic gonadotropin (hCG) during pregnancy. What this hormone does is tell the body (corpus luteum) to produce progesterone to maintain the pregnancy. The presence of Human chorionic gonadotropin is a sign of pregnancy, meaning successful fertilization had happened, and implantation of the embryo had occurred too, preventing another cycle of menstruation.
The successful development of a mature, full-term fetus also depends on estrogen which during pregnancy aids the formation of blood vessels and also aids fetal maturation. While progesterone is a hormone when released during pregnancy helps maintain a healthy pregnancy.

experiment yeast fermentation ，what is the purpose of boiling the glucose solution earlier？
Answer:
The correct answer is - to sterilize it and remove any oxygen.
Explanation:
Boil the glucose solution to sterilize it and remove any oxygen, leaving behind the glucose needed for anaerobic respiration. High temperature kills all the microbes and sterilizes the solution.
Boiling the glucose solution earlier also helps in removing the oxygen from the solution for preparing the anaerobic respiration in the experiment desired. Sterilization of the solution also helps it in avoiding any microbes to present in the solution and affect the experiment.
