Answer:
Pregnancy, which is characteristically associated with changes in hormone levels in the body is a process tightly regulated by the hormon Human Chorionic Gonadotropin
Explanation:
The so-called pregnancy hormone is the Human Chorionic Gonadotropin (HCG). It only occurs during the gestation period and is responsible for regulating the entire process. Segregated by the placenta, it can be found in urine and blood.
The presence of the hormone in the urine allows to confirm the pregnancy with the test. As in pregnancy, the placenta begins to form, the cells that make it up begin to stimulate the production of HCG, which causes the hormone levels to increase very rapidly in the first trimester of pregnancy
Answer:
plants process oxygen for respiration as an aerobic organism and also produces it, light can regulate this metabolism, which means that in the presence of light oxygen generation occurs as well as consumption and when there is darkness only consumption will occur Thus, when calculating the amount of oxygen that a plant produces during photosynthesis, it will be necessary to subtract the oxygen it consumes, from which it is deduced that the rate of oxygen consumption will not have variations and will be the same in the day and in the At night, so the change of oxygen in the dark is subtracted with the change of volume of oxygen in the light phase
Answer: D.) This gene sequence ensures transcription of arabinose genes only
when arabinose is available, saving the cell from expending energy
unnecessarily
