It would be B. Geologic time
The correct answer is: C. They transfer energy through a medium
There are different types of waves, depending on their medium: electromagnetic (energy is transferred through vibrations of electric and magnetic field), sound (energy is transferred through vibration of air particles), water (energy is transferred through the vibration of the water particles).
Longitudinal waves - particles vibrate parallel to the direction of wave propagation
Transverse wave -particles vibrate perpendicular to the direction of wave propagation.
Answer:
4 1/4
Explanation:
17/4 = 4/4 + 4/4 + 4/4 + 4/4 + 1/4
4 + 4 = 8
4 + 4 = 8
8+8=16 = 16/4
16/4 + the 1/4 remaining in the equation = 17/4
so 4/4 + 4/4 + 4/4 + 4/4 = 4
4 + 1/4 = 4 1/4
sorry if you couldnt follow along. I am not good at explaining things but the answer is 4 1/4
(I also took the test)
The answer is cerebellum. By processing and interpreting impulses from the motor cortex and brain stem nuclei as well as sensory pathways, the cerebellum provides the precise timing and appropriate patterns of skeletal muscle contraction for smooth coordinated movements and agility needed for daily living. It also plays a poorly understood role in cognition. Cerebellar activity occurs subconsciously (e are not aware of it).

Generally speaking, enzymes (which amylase happens to be) do not undergo any permanent structural change while carrying out their function. Some do exhibit transient conformational change during a reaction, but upon completion regain their original form.
So your initial assumption is correct: once amylase has finished catalyzing the breakdown of starch into less complex sugar molecules, it moves on and repeats the process over and over.
