28. Sharon pushes a toy car and lets it go. The toy car rolls and gradually comes to a stop. What would make the car stop? A. A force must be applied to the car in a direction opposite to that in which it is moving,
BA force must be applied pushing the car forward in the same direction as the moving car.
CA force must be applied in a direction pushing the car upward to make the car stop.
D. A force must be applied in a direction pulling the car downward causing the car to stop.
29. The amount of matter in an object is called its
A
inertia
B.
C. force
D. balance
mass

Explanation:

is BA force must be applied pushing the car forward in the same direction as the moving car.

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
