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 (see Figure below). 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
a) Show that the chemical potential of water in compartment A is lower than that in compartment B by 2.48 J/mol.
b) As a result of this chemical potential difference, water molecules will move from compartment B to compartment A. This causes the pressure in compartment A, relative to that in B, to increase. How would this affect the chemical potential of water in compartment B? When would the diffusion of water from B to A cease (i.e. equilibrium is achieved)?
c) Using your answer to part (b), work out the difference between the pressure in compartment A and B when…

- A patient needs 1mg of a medication. The Australian Injectables Drug Handbook states that each gram of this medication is to be mixed with 10mL of water over 3-5 minutes via IV bolus. After preparing the medication, how many mL per minute would you administer if you do it over 3 minutes? Please do it in dimensional analysis or something please show work.

(more than one answer may be correct) which are correct a.increase the length of lipids with short hydrocarbon tails b.increase the number of steroids in the cell membrane c.more saturated lipids in the membrane d.reduce the proportion of lipids with short hydrocarbon tails e.more unsaturated lipids in the cell membranearrow_forwardImagine 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_forward

- Electrically 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_forwardInformation: 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_forwardFor dinner you eat 2 slices of a 14" thick crust pizza.

- Alice 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_forward1. Explain the three components of homeostatic control. Also, compare and contrast negative vs. positive feedback mechanisms and give an example of each type and explain. 2. Clearly explain how hydrogen bonds are formed using water as an example. [Hint: Include electron structure of water and include what relative electronegativities are and how they work to develop partial +/- charges.] 3. Define osmosis and characterize isotonic, hypertonic and hypotonic solutions and what happens to the cell(s) when placed into these solutions and the direction of water movement if any. Also, state which tonicity is optimal for animal cells and why. 4. Describe in detail how the sodium/potassium pump works and give at least one example of why it is important in the body.arrow_forwardThe pH in your cells is decreasing. Cells have buffers to minimize changes in pH. Briefly explain what the buffer would do in this situation with respect to the H+ concentration in your cells.arrow_forward
