When we think about the effects of air pollutants we immediately think of respiratory issues. Exposure to one criteria air pollutant has harmful effects on the cardiovascular system including increased occurrence of heart attack and
stroke. These effects can result in emergency department visits, hospitalizations and, in some cases, premature death.
As expected, exposure to this pollutant is also linked to harmful respiratory effects, including asthma attacks. What is
this pollutant?

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
