Question Answered step-by-step 1. What is the immediate cause of menstruation (breakdown of the… 1. What is the immediate cause of menstruation (breakdown of the uterine lining)?A drop in estrogen levelsThe implantation of the zygote into the endometrial wallAn increase in the levels of estrogenAn increase in the release of progesterone from the corpus luteumAn increase in the release of FSH from the pituitary gland 2. Constriction of blood vessels to the hands and the feet is most likely a response to:Increasing body temperatureHyperthermiaDecreasing body temperatureIncreasing blood glucose concentrationDecreasing blood glucose concentration 3. What is the result of an increased amount of aldosterone being released from the adrenal cortex?Decreased production of ADHIncreased blood pressureVasodilationVasoconstrictionIncreased rate of glycogen breakdown4. When a neuron generates an action potential, what happens to the potassium ions?The concentration of potassium ions becomes greater outside the neuron than inside itThe concentration of potassium ions becomes greater inside the neuron than outside itThe concentration of potassium ions becomes equal inside and outside the neuron Nothing – potassium ions are not involved in action potentials5. What is the function of FSH in males?FSH is not produced in males; it is a female hormoneFSH is directly responsible for facial hair growth, which begins at pubertyFSH stimulates the release of semen from the prostate gland during ejaculationFSH is produced by the hypothalamusFSH stimulates the development of sperm in the testes6. In a research lab, an anesthetized mouse has a fine tube inserted into one of its ureters. When a small amount of concentrated glucose solution is injected into a vein, there is a sharp increase in the number of drops of urine that are excreted into the tube. What inference can be drawn from this observation?Glucose in concentrated solution is isotonic to the extracellular fluidThe rate of formation of urine increases with the amount of plasma increasesThe amount of glucose in the urine increases if the sugar content of the diet increasesGlucose is actively transported out of the nephron, making the surrounding tissue hypertonic to the filtrateGlucose affects osmosis, one of the mechanisms that is involved in the formation of urine Biology Science Physiology BIOL 1001 Share QuestionEmailCopy link Comments (0)
