Which one of the following is a function of the lungs!
A) To pump oxygenated blood to all parts of your body
B) To transfer some of the oxygen that you breathe to your blood
C) To purify your blood by reducing the carbon dioxide content to zero
D) To convert carbon dioxide molecules into oxygen molecules.

D

Explanation:

The main function of the lungs is the process of gas exchange called respiration (or breathing). In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood.

Smoking can cause lung disease by damaging your airways and the small air sacs found in your lungs. Lung diseases caused by smoking include copd, which includes emphysema and chronic bronchitis. If you have asthma, tobacco smoke can trigger an attack or make an attack worse.

D) To convert carbon dioxide molecules into oxygen molecules.​

your the dumbest b**tch ive ever seen

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
