Define Mendel's law of independent assortment. Group of answer choices The expression of one gene has no effect on the expression of another gene. There are two versions of each trait, a dominant and a recessive; the one you get is random. Segregation of homologous chromosomes is random. The inheritance of one character has no effect on the inheritance of another character.

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
