The body needs what in only small amounts, but these organic molecules are an important part in helping perform cellular reactions?

Answers

Answer 1
Answer:

Answer:

Vitamins

Explanation:

Vitamins are the organic compounds that are needed by body in small amounts. Most of the vitamins are not synthesized in human body and should be supplemented with food. Vitamins serve as coenzymes or part of coenzyme which are required for the activity of respective enzymes. Hence, vitamins an important part in helping perform cellular reactions.

Answer 2
Answer: Vitamins. They are needed in small amounts for chemical reactions in the body, and they are also organic.

Explain why animals must eat but plants don't eat

Answers

Plants don't need "food" to function. They use sun light/photosynthesis and minerals from the soil to make the sugars they need in order to grow and survive. Animals are not at all like plants (Due to the fact that animals can't use sunlight to produce the energy that they need to live), so they need to take in organic/physical sources of energy in order to function. So that's one reason why animals eat, and plants don't. :P 
Animals must eat because they are a living mammal. Plants are not humans or living mammals, all they need is sunlight, rain. Animals should it because they need their nutrition to live. Plants also need nutrition but not as in eating something, they get it.

Which of the following is a demonstration of the polarity of water?A) A stream of water bending toward a balloon due to the balloon have a static charge from being rubbed on a sweater

B) Water clinging to each other and as a result forming a droplet on a penny

C) Water clinging to the side of a windshield after a rain

D)All of the above

Answers

Answer:

D)All of the above is your answer

Answer:

All of the above

Explanation:

In letter A, B, and C; in different physical situation the molecule of water behave and put in charge with its peculiar polarity. Remember that is part its quite simple and molecular structure.

Water is "dipolar", because there is an uneven distribution of electron density. Water has a partial negative charge (Delta-) near the oxygen atom due the unshared pairs of electrons, and partial positive charges (Delta-) near the hydrogen atoms.
