<span>What materials are involved in cellular respiration?
</span>Cellular respiration requires energy
from an organic source, such as glucose and oxygen, to take place.
Cellular respiration is the process by which energy is harvested from an
organic source and then stored in the form of ATP to later carry out
reactions in the cell. Without the organic source of energy, the
reactions cannot take place. Oxygen is needed to serve as the final
electron acceptor in electron transport.

would be perfectly safe for Betty to swim around and make sure the
water is deep enough. If she finds that it is, the cliff could be a good
place to practice.

It depends on the runner. Depends on how comfortable you are wearing the certain type of comprehension socks.
When the skin is exposed to ultraviolet rays, the skin produces a molecule that is turned into Vitamin D.
Sun is the source of ultraviolet rays important for Vitamin D production. Due to this reason, in the case of Vitamin D deficiency, it is recommended by doctor's to absorb sunlight by skin. The Vitamin D production occurs specifically by UV B rays rays which lie in the range of 290-315 nanometer.
The chemical 7-dehydrocholesterol absorbs these rays and convert to previtamin D3. Further, previtamin D3 isomerizes to Vitamin D. Other than sunlight, Vitamin D can be taken through diet. The sources include seafood like fish, fish oil, dairy products, beef liver etc. Vitamin D is required for bone and teeth formation, muscle contraction, immune system etc.
