in which way will energy be used after it leaves the mitochondrion during cellular respiration?
repairing parts of damaged tissue
combining with carbon dioxide
building new oxygen molecules
starting the second stage of respiration

i had this on my unit activity, i can you if you are a plato student. are you a plato student?

c is the answer because when something is left after something evaporates that shows the chemical change.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
