c. Did average cardiac cycle length increase, decrease, or not change with exercise?
d. What was the average resting EDV? What was the average exercising EDV?
e. Did average EDV increase, decrease, or not change with exercise?

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.

helicase, i think thats it

b. lithosphere, asthenosphere, mesosphere   is the answer most likely
