carbon dioxide
The capillaries absorb oxygen at the lungs. This occurs near the alveoli.
They absorb oxygen to carry to the rest of your body
Several substances bind with oxygen in the air. Some examples are the hemoglobin in our blood and the iron that reacts with oxygen to become rust.
Hemoglobin is a protein in red blood cells that can absorb oxygen. It binds to oxygen in the lungs, carries it through the bloodstream, and releases it to cells throughout the body.
Seawater and fresh water contains oxygen that fish absorb using their gill. So the substance is oxygen.
Oxygen is restored to the air as a byproduct of photosynthesis. During photosynthesis, plants absorb carbon dioxide and water and convert them into glucose and oxygen through the process of photosynthesis.
No, rocks do not absorb oxygen. Rocks are composed of minerals and do not have the ability to undergo the chemical process of absorbing oxygen.
Humans take oxygen from the air and absorb it into the blood through the process of respiration.
No, plants do not absorb oxygen at night. Instead, they release carbon dioxide through a process called respiration.
I'm not sure, but it might be haemoglobin? I think. :-)
No, plants do not absorb oxygen as part of photosynthesis. Instead, they take in carbon dioxide and water to produce glucose and oxygen as a byproduct.
