Which of the following accurately describes an example of how materials can move across the cell membrane through active transport

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.

the answer is admiramos

the rule for verbs is whoever you are referring to (in this case 'nosotros'), you need to change the ending of the word.

nosotros - amos

yo - o

tu - as

el, ella, usted - a

ellos, ellas, ustedes - an

(examples: nosotros bailamos (instead of bailar) or yo hablo (instead of habla)

the correct answer is:

a population changes in response to a change in the environment.
