How do cats drink? Scientists using high-speed video have that cats use an interesting technique to drink aqueous substances like water and milk. Four times a second, the cat touches the tip of its tongue to the water and draws a column of water up into its mouth (as you can see in the photo), which then shuts before gravity can pull the water back down. Describe how the properties of water allow cats to drink in this fashion, including how water’s molecular structure contributes to the process.

Don't explain, I just want the correct choise
In an experiment, a 0.001 (mole fraction) solution of polysaccharide in water is made and is placed in the compartment A. Compartment B is filled with pure water. The two compartments are separated by a porous semi-permeable membrane that allows the exchange of water molecules between the two compartments, but not that of the larger polysaccharide molecules.
part 1: Show that the chemical potential of water in compartment A is lower than that in compartment B by 2.48 J/mol.

- Imagine that you have a jar of syrup A and a plastic Ziploc bag of syrup B. You poke tiny holes in the bag and put it inside the jar. Where will water move? Hint: remember that water moves from the more watery area (high concentration of water) to the less watery area (low concentration of water). Water moves from the bag (B) to the jar (A) Water moves from the jar (A) to the bag (B)arrow_forwardManufacturers make carbonated drinks by forcing pressurized carbon dioxide gas into flavored water. A chemical reaction between water molecules and some of the CO2 molecules creates hydrogen ions (H+) and bicarbonate, which is a buffer. In your opinion, is this reaction likely to raise the pH of a soda above 7, or lower it? Give your reasoning.arrow_forwardElectrically neutral molecules can pass through cell membranes more easily than charged molecules can. Aspirin has a carboxylic acid group with a pKa value of 3.5. In order to be absorbed into the bloodstream it must pass the membrane lining the stomach and intestine. Would you expect more aspirin to be absorbed in the stomach (pH 1) or in the small intestine (pH 6)?arrow_forward
- Information: Osmotic pressure is the pressure that a solvent exerts against a semipermeable membrane, such as a cell membrane. The higher the solute concentration, the lower the osmotic pressure. Red blood cells have an osmotic pressure equal to that of a 0.90% (m/v) solution of sodium chloride and 5.0% (m/v) solution of dextrose. A solution that has a higher concentration that this is called hypertonic; one with a lower concentration is called hypotonic. Osmotic pressure is an important factor affecting cells. Osmoregulation is the homeostasis mechanism of an organism to reach balance in osmotic pressure.Hypertonicity is the presence of a solution that causes cells to shrink.Hypotonicity is the presence of a solution that causes cells to swell.Isotonicity is the presence of a solution that produces no change in cell volume.When a biological cell is in a hypotonic environment, the cell interior accumulates water, water flows across the cell membrane into the cell, causing it to…arrow_forwardBased on the pH of your drug, if your drug was in a high concentration in the blood,how would it affect the pH of your blood. Would it cause acidosis or alkalosis, and how would you treat this? drug Lipitor ph is 7 it's acidosis?arrow_forwardAlice reads another paper which seeks to elucidate the interaction of GLUT1, LAT1 and the movement of water. In the paper, the authors set up artificial cells which mimic the endothelial cells. Embedded in the artificial cell membrane is a deformed GLUT1 protein which does not work, a normal LAT1 protein and aquaporins. The artificial cell is submerged in a beaker of water which contains 10 picomole of phenylalanine. After several minutes where will water move? a) Water will move out of the artificial cell. b) Most of the water will move out of artificial cell. A little will move in. c) Water will move into the artificial cell. d) Most of the water will move into the artificial cell. A little will move out.arrow_forward
- two of these statements are truths and one is a lie. Which of the following statements is a lie? a. The concept of pH is exclusive of how buffers work. b. Salts dissociate into ions (except H+ and OH-) when dissolved in water. c. ATP stores a large amount of potential energy.arrow_forward2. The gastric juice in your stomach lumen has a pH of 2. The acidity of this "juice" is due to the secretion of H* into the lumen by epithelial cells of the gastric mucosa. Epithelial cells have an internal pH of 7 and a membrane potential of -60 mV (inside is negative) at 37°C. A) Calculate the free energy change associated with the secretion of 1 mole of H¨ into gastric juice at 37°C.arrow_forwardDiscuss Concepts You place a metal pan full of water on the stove and turn on the heat. After a few minutes, the handle is too hot to touch but the water is only warm. How do you explain this observation?arrow_forward

She begins to have a severe headache and shows symptoms of being confused. She has been sweating profusely, losing elec- trolytes and, to compensate, has been drinking pure water.
