6. Individual fossil species have much shorter geologic ranges than the group as a whole. If you were to find an ostracode preserved in a sedimentary rock, it might be of any age from Cambrian to Recent. However, if you could identify the particular species of ostracode, it might give you the age of the rock within a few million years. Commonly, assemblages of several types of fossils are found together in a rock. This can also help you determine the age of the rock more closely. For example, if you had an ostracode fossil and a planktonic foram fossil together in a rock, what would this tell you about the age of the rock

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
