If the ph of a solution is increased from ph 5 to ph 7, it means that the concentration of h+ is twice (2x) what it was at ph 5. concentration of h+ is one-half (1/2) what it was at ph 5. concentration of oh- is 100 times greater than what it was at ph 5. concentration of h+ is 100 times greater and the concentration of oh- is one-hundredth what they were at ph 5.

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.
