Es - matt and brad own a ice cream store and they believe they have the best ice cream in town. they invite ten of their closest
friends to their ice cream shop, give them free ice cream, and then ask for their opinions. brad and matt encouraged their friends
to try other ice cream shops, but they told them that they would have to buy the ice cream there. after a week, matt and brad
took all the participants out to dinner and 90% of the 'tasters' voted matt and brad's shop to be the best in town.
which of these would not lead to bias in this experiment?

You have a solution that contains phospholipid vesicles in a test tube. these vesicles have phospholipid bilayers, but do not contain any membrane transporters. you add a number of different molecules to the solution, and wait a period of time for them to equilibrate. if you could measure the concentration of each molecule, for which of the following would you expect to measure equal concentrations inside and outside of the vesicles? assume for this question that the overall osmolarity inside and outside the vesicles is the same (that is, there is no appreciable diffusion of water across the membrane). (select two answers) an amino acid with a hydrophobic side-chain a small non-polar molecule a negatively charged ion a small polar molecule a small lipid hormone

Which mechanism of transport takes place when solute particles move from a region of high concentration to a region of low concentration? active diffusion isotonic osmosis
