Consider an experimental setup with two compartments separated by a phospholipid bilayer membrane containing open ion channels selectively permeable only to chloride ions. The left compartment (also called inside) contains 1 mM Cl- and the right compartment (also called outside) contains 100 mM CI- What will the electrical potential be (inside relative to outside) when the system attains equilibrium? (assume body temperature; log 100 = 2, log 10 = 1; log 1 = 0; log 0.1 = -1; log 0.01 = -2] a.-62 mVb.-124 mv c.+62 mv d. Omv e.+124 mv

Cladistics is a way of classifying organisms by examining the characteristics of their ancestors and descendants and depicting the relationships in a cladogram. which of the following best describes a challenge in classifying organisms this way? a. there are millions of species on earth, and a cladogram is not a practical means for classifying all of them. b. it is impossible to tell which organisms are most closely related to each other using a cladogram. c. cladograms are detail-oriented and do not provide a useful understanding of evolutionary relationships. d. there is a limited number of ways to organize the information, so most cladograms end up looking very similar.
