Answer:
A. chemical energy to kinetic energy
B. chemical energy to thermal energy
D. potential energy to kinetic energy
Explanation:
Food produces chemical energy, standing still, potential energy, running kinetic energy and her body warming up is thermal energy(heat energy)
They are said to be “denser” than air. what happens is that light slows down when it passes from the less dense air into the denser glass of water. this slowing down the ray of light also causes the ray of light to change directions. it is the change in the speed of the light that causes refraction.
Answer:
B
Explanation:
Gas exchange provides oxygen that is required for aerobic cellular respiration. Aerobic respiration produces more ATP molecules than anaerobic respiration. This is because oxygen acts as the ultimate proton acceptor (in the Krebs/Citric cycle) in the matrix of the mitochondria to form water as the waste product. This allows a proton motive force to be created in the mitochondria that is harnessed by ATP synthase to produce ATP molecules.
