6. The film describes two independent sources of evidence that have been used to estimate when maize was
first domesticated: genetic evidence and archaeological evidence. Do these two sources of evidence support
each other? Explain your answer.
7. To demonstrate how two different genes can explain the different traits in teosinte and maize, Dr. Doebley
and colleagues used careful breeding to transplant each gene from one type of plant to the other. In the
table below, draw and/or describe the results of each cross and explain what you can infer about the
function of the genes.

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
