Ahuman kidney filters about 200 liters of blood each day. approximately two liters of liquid and nutrient waste are excreted as urine. the remaining fluid and dissolved substances are reabsorbed and continue to circulate throughout the body. antidiuretic hormone (adh) is secreted in response to reduced plasma volume. adh targets the collecting ducts in the kidney, stimulating the insertion of aquaporins into their plasma membranes and an increased reabsorption of water. if adh secretion is inhibited, which of the following would initially result?
a) number of aquaporins would increase in response to the inhibition of adh.
b) the person would decrease oral water intake to compensate for the inhibition of adh.
c)blood filtration would increase to compensate for lack of aquaporins.
d) person would produce a greater amount of dilute urine.

Every compound can be represented by a chemical formula. a chemical formula is the set of symbols showing the elements that make up a compound and their proportions. water’s chemical formula is h 2 2 o. that means a molecule of water contains two atoms of hydrogen and one atom of oxygen chemically bonded. a molecule is a group of two or more atoms bonded together. molecules can range in size from two to thousands of atoms. a molecule of a compound is the smallest unit of that compound. every molecule of water has all the physical and chemical properties of water. that’s because every molecule of water is made of the same elements in the same proportions: two hydrogen atoms and one oxygen! which of the following is a true statement? a every molecule of the same compound will have different properties. b every molecule of a compound has the same proportion of elements. c molecules can be physically separated into smaller units of a compound. d molecules cannot be represented by chemical formulae.
