That easy..............<span>21 one is your technical answer according to todays rules but scientist used to think it was only 20 so 20 would be your answer</span>
The following choices are provided;
One plate moves below the other due to the movements in the inner core.
One plate moves below the other due to the movements in the mantle.
A plate slides past another due to the movements in the inner core.
A plate slides past another due to the movements in the mantle
The answer is; One plate moves below the other due to the movements in the mantle.
It is common that such convergent boundaries have a cascade of volcanic ranges. This is because as the oceanic plate moves below the continental plate the pressure and high temperatures cause the rock to melt and become magma. The magma makes it way up the crust through fissure and erupts.
Answer:
The correct answer is option c. "Enzyme lowers the activation energy".
Explanation:
The activation energy is defined as the amount of energy needed for a reaction to take place. Enzymes catalyze reactions by lowering the activation energy, which speeds up the reaction and increases its rate. Enzymes put a substrate in its active site, which facilitates the reaction and makes more likely that it collides with its subsequent substrate.

Answer:
D. A bicycle rusting.
Explanation:
A. is incorrect because tearing a piece of paper is a physical change, not a chemical change.
B. is incorrect because we are just heating up the object. That only changes how fast the particles are moving and the change in state of matter.
C. is incorrect because we are adding heat to change a state of matter (from solid to liquid) and it is a physical change.
Therefore, only D. is the correct answer. Iron rusts, and when it does, it chemically changes into an iron oxide (rust).
