Which of the following statements is/are true? check all that apply. check all that apply. the total mechanical energy of a system is constant only if all the forces doing work on it are nonconservative. the total mechanical energy of a system is constant only if all the forces doing work on it are conservative. the total mechanical energy of a system is equally divided between kinetic and potential energy. mechanical energy can be dissipated to nonmechanical forms of energy. the total mechanical energy of a system, at any one instant, is either all kinetic or all potential energy.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
