In simple terms, momentum is the measure of mass in motion, ie. how much amount of mass is in how much motion. Impulse on the other hand is the overall effect of a force acting over time. Impulse is equivalent to a change of momentum. Because of this relation, there is a direct connection between a force that acts on an object over time and the motion itself. So, a roller coaster moving at a high speed has a lot of momentum.
Since momentum is velocity * mass, the velocity needed at the bottom of the roller coaster to make it all the way up to the top of the loop is independent of the mass.
Thus, the more the momentum on the roller coaster, the harder it is to stop it or change its direction.

Answer:
The correct answer is C. benefit ... harmed
Explanation:
Predation is a type of interaction between two individuals in which one individual gets harmed which is called prey and another organism who is predator gets benefitted.
In predation, the predator kills its prey and consume it to survive. For example, Lion is a predator and deer is the prey so during predation lion kills the deer and consume it so here lions get benefited by consuming deer and deer is harmed as it lost its life. So the correct answer is C. benefit ... harmed.
A river that comes from rain, glaicers etc would be a good example of fresh water rivers. Cause the water is coming from something that is most likely been unthouched by man or has been filterd and cleaned from minerals in the ground.
