Underground mammals, such as the ancestors of moles, are thought to have first evolved as the dinosaurs died out. Which effect of an environmental change does this best illustrate?

Moles did not evolve from dinosaurs.

Explanation: In the beginning, God created the Heavens and the Earth and made all animals according to their kind. He then made humans on the sixth day; animals cannot turn into something else nor humans into something else.

i'm assuming that the correct answer is indeed the first one/ "a"..

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
