The replication of DNA is a complicated process during which DNA is occasionally damaged. Discuss when in the cell cycle DNA is assessed for damage and predict what effect DNA damage would have on the cell cycle.

What do animals wth echolocation have in common other than echolocation

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

What is the answer for the complicated molecules that make up living things usually contain carbon. why is carbon so important in these molecules?
