For finches on the Galapagos, a significant change in beak size can be observed across years with plentiful rainfall or intense drought. How can the changes in finch beak size be attributed to evolution?

A) Finches on the island with better-adapted beak sizes have increased survival.
B) Finches on the island are domesticated and are artificially selected for beak size.
C) Finches on the island without well suited beak sizes change their diet to induce and enhance growth of their beaks.
D) Finches on the island reproduce with finches from nearby islands that have larger beaks, resulting in changing beak sizes over time.

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
