The ADH system regulates water balance by decreasing water reabsorption and increasing excretion of salt. c. Receptors in the juxtaglomerular apparatus detect a higher salt concentration in the distal convoluted tubule and trigger constriction of the afferent arteriole to reduce glomerular filtration rate. d. ANF is released by the kidney to increase renin release. e. Angiotensin II lowers blood pressure by constricting arterioles.Please answer all thq questions. There are all the questions that are left.

Group of answer choices The plasma concentration of glucose becomes so high that it diffuses from peritubular capillaries into the proximal tubule, down its concentration gradient. The filtered load of glucose becomes greater than the tubular maximum for its reabsorption. Without the hormone insulin, glucose cannot enter proximal tubule epithelial cells. The rate of tubular secretion of glucose becomes greater than the sum of glucose filtration and reabsorption.

- Which of the following would NOT occur with increased plasma potassium during intense exercise? a.increased resting membrane potential b.decreased calcium release from the SR c.decreased height of the t-tubular action potential d.a delay in the inactivation of the sodium channels Explain why you chose the answer and why other options are wrongIf plasma osmolarity is the independent variable and vasopressin release is the dependent variable, which graph would best describe their relationship? Please thoroughly explain the effect on the dependent variable if the independent variable increases so I can fully understand the concept.Answer a, Anti-Diuretic Hormone (ADH) and Aldosterone both target kidney cells and increase water retention (keeping water in the blood, letting less go out with urine). ADH causes water retention directly- kidney cells let more water move from the urine back into the blood (the cells are a barrier between those two spaces). Aldosterone enhances water retention by causing more sodium to be retained, creating a stronger osmotic gradient. However, aldosterone also causes a loss of potassium to the urine for every sodium that is kept in the blood. a. Are these hormones both water-soluble or fat-soluble, or is there one of each? b. What chemical class does each belong to? c. Draw a picture hypothesizing how each might cause its target cells to have their effects. Don't look it up! You have all the information you need from the notes and explanation in this question to come up with a reasonable, logical hypothesis. d. If somebody has hyper-aldosteronism (secrete too much aldosterone,…
