What is respiration? A. When carbohydrate (glucose) and oxygen create water and carbon dioxide releasing energy

B. When water and carbon dioxide create carbohydrate and oxygen releasing energy

C. When carbon dioxide absorb energy to make water

D. When carbohydrate and oxygen absorb energy to make water

A

Explanation:

Organisms use respiration to generate energy. Aerobic respiration is when glucose (food) is broken down in the presence of oxygen to produce energy and CO2 as a byproduct.

The process of getting oxygen into the body and releasing carbon dioxide is called respiration. ... Breathing is only the movement of oxygen into the body and carbon dioxide out of the body. The process of respiration also includes the exchange of oxygen and carbon dioxide between the blood and the cells of the body.

i believe it would be the lungs.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
