Answer:
Potential & Kinetic energy.
Explanation:
The water used gains potential energy overtime before it is converted to mechanical (or kinetic energy). This can be explained by the water having increased potential energy as it flows at an equal altitude, but converting to kinetic energy as it flows downhill, or over the dam.
This kinetic (or mechanical) energy is then converted to traditional electricity. This process is also an example of a renewable resource being utilized for everyday things (such as powering cars, homes. or charging batteries).
Answer:
D. caused by vibrations. B. A form of energy. F. A type of electromagnetic wave
Explanation:
Answer:
Root hair cells are alive and therefore need energy, which is why root hair cells contain many mitochondria in them. Root hair cells don't contain chloroplasts. Chloroplasts are used by the plant to make food using light energy. Since the roots aren't exposed to any form of light, they have no need for chloroplasts.
B. Proteins
Hence why body builds drink protein shakes in order to build muscle.
Answer:
