Apopulation of aliens with similar genetics as humans is affected by a homozygous recessive condition known as "xbziq." this condition causes aliens to die at young ages because their digestive tracts are not able to effectively process food and obtain the necessary nutrients and energy from their diets. approximately 2% of the newborn aliens have the xbziq condition. what is the carrier (heterozygote) frequency in the population?

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
