What happens first during cellular respiration?

A. The movement of small organic molecules into a mitochondrial

B. The breakdown of food molecules into smaller organic molecules

C. The formation of many molecules of ATP

D. The breakdown and small organic molecules into carbon dioxide

i believe the correct answer from the choices listed above is the first option. the scientists need to look at the   validity of data, claims, hypotheses, and observations before  developing an argument. they base their arguments on facts that are present and they make sure they have proofs. 

explanation:

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.

i do believe the correct answer would be the third one. location c, because earth is tilted away from the sun at this time

hope this
