Corals, the basic structures of coral reefs, are affected by the increasing acidity (decreasing pH) of the
oceans. When the ocean absorbs carbon dioxide, the carbon dioxide reacts with water and other
substances to form carbonic acid. This process uses substances in the ocean that corals use to build
their skeletons. So, the more carbon dioxide there is in the ocean, the harder it is for corals to build their
skeletons. Ocean acidification can also destroy existing coral reefs.
1. Give two possible ways that negative human impact on the pH of Earth’s oceans can be reduced.

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

Pepsin is an enzyme in the stomach that breaks polypeptides into amino acids. pepsin functions best at a ph of around 1.5. what would be the most likely result if the ph of the stomach were increased to 5
