10.All of the following are true of a cell that is hypertonic to its solution EXCEPT: a.the intracellular fluid has more dissolved solutes than the extracellular fluid c.the extracellular fluid has a lower osmotic potential than the cellb.the cell will swell d.specific molecules will leave the cell via aquaporins 56% got this correct. This will always be the case. Students will always confuse hypo- and hypertonic. Questions like this in the past six years of teaching this class always result in 50% averages. 11.Which of the following bonds are the weakest: Only 35% got this correct. A is a covalent peptide bond. B is a covalent glycosidic bond. C are hydrogen bonds. D are covalent phosphodiester bonds. 53% of you chose D. I personally think this is because you memorized my last semester’s exam question and didn’t realize I swapped out guanine for thymine in choice D. Below is that old exam question (that I’m now certain that at least 53% of the class has copies of). Unfortunately for many of you, I’m not lazy. I actually care and rewrite my questions. 11. Which of the following bonds are the weakest: 12.Which of the following is not located on the lateral surface of an epithelial cell: a gap junction a hemidesmosome 54% got this right. 18% chose E. Gap junctions are on the lateral membrane. This is clearly illustrated in your notes. I didn’t leave you to discover this on your own though, I lectured on it as well.

I’m not sure why 31% chose C? A mesentery is a double layer of visceral peritoneum right?
