What is one similarity between the lungs and capillaries? (5 points) they are both activated by inhalation. they are both involved in gas exchanges. they are both part of the circulatory system. they are both regulated by the heart.

They are both involved in gas exchanges.

Explanation:

This is the answer because:

1) Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. Inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.

2) Also, capillaries are located inside the lungs. Therefore, whenever we breathe in air we exchange gasses.

Hope this helps! :D

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
