The roller coaster in this interactive is a model. In real life, not all of the potential energy of the coaster cars is converted to kinetic energy and back again; some
mechanical energy is converted to thermal energy. Describe how mechanical
energy gets converted to thermal energy along the track. How does this
conversion affect the potential energy and kinetic energy during the ride? *

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.
