Oxygen
we inhale oxygen and exhale carbon dioxide
Oxygen is used to help people breathe in and out
No, there is not enough dissolved oxygen in water for humans to breathe. Aquatic animals have adapted to extract oxygen from water using gills, while humans would need specialized equipment like scuba gear to breathe underwater.
Humans (and most, and if, not all other organisms) need nitrogen is to produce protein. Oxygen is used up in respiration to help produce energy used by the human (and other organisms, but not plants) body.
No, it is not possible to become physically dependent on oxygen as it is a necessary element for sustaining life. While you may experience withdrawal symptoms if oxygen levels are suddenly reduced, this is due to a lack of oxygen rather than dependence.
We need to breathe oxygen because it is essential for our cells to produce energy through a process called cellular respiration. This energy is used to fuel our bodily functions and keep us alive. Without oxygen, our cells would not be able to produce enough energy to sustain life.
In order to live.
yes, animals, humans, and even plants nêd air to live
Whales need to breathe air because they are mammals, like humans, and require oxygen to survive. Even though they live in water, they have lungs and need to come to the surface to breathe.
in order to
No, humans do not need nitrogen to breathe for survival. The air we breathe is primarily made up of oxygen, with only a small amount of nitrogen.
Marine mammals live and water and they need to surface to breathe. While land mammals can breathe just as humans do.
Absolutely. It's what we breathe.
lungs and muscles
the suit of astronaut
because we need it in our lives in order to eat, live, breathe. . . etc.and its just great!!!
Oxygen is the gas humans and animals need to breathe in.
The air that one breathes to keep electrons moving along from the first to the last chemical carrier is oxygen. Oxygen is necessary for all life forms to exist and enable existence. For instance, humans need the trees and plant life because they take in or breathe the carbon dioxide that humans expel, and then expel the oxygen that humans need to breathe in order to maintain life.
