Identify the hypothesis, Ian's dependent Variable. Jamal is a sprinter on the track team and often runs the 100 meter dashIn the past he noticed many of his competitors had shaved their legs in preparation for large track meetsJamal asked them about it, and they said that shaving their legs made them run fasterSince he wants to drop time Jamal creates a miniature experiment to see if shaving legs actually helps sprinters drop time. One day at practice he runs the 100 meter dash ten times. He records his times and finds the average . Later in the week, he shaves his legs and runs the 100 meter dash another ten times. Again he records his times and averages them . He compares the averages to see if shaving makes a difference in his speed. Independent Variable: Dependent Variable: Hypothesis; mi

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
