Animals exhale to get rid of carbon dioxide in the body in what way do cell functions the same? A. They transport needed nutrients to various cell parts.
B. They break down food to obtain energy.
C. The remove waste created by cellular activities.
D. They sense stimuli and response

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.

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.

hope it ,
