Q

how is the conservation of matter shown when a cow eat grass?

A

a cow receives the glucose it needs by eating grass and other plants. the cow’s digestive system performs many chemical reactions that break down the plants into smaller molecules. the cow then uses these molecules to create new biomolecules that grow new cells, repair body tissues, and perform other cell functions.

Q

why are organisms what they eat?

A

due to the laws of conservation of matter, all atoms that enter a chemical reaction will be used to make the substances formed during the chemical reaction.

Q

what does the integumentary system and why does it need cellular respiration?

A

it grows new tissue to replace the damaged skin. this process requires a lot of energy. this energy is produced when glucose and oxygen are used to make ATP during cellular respiration.
