They drink it.
No, oxygen-17 and oxygen-18 are different isotopes of oxygen. They differ in the number of neutrons each atom contains. Oxygen-17 has 8 protons and 9 neutrons while oxygen-18 has 8 protons and 10 neutrons.
4 liters of oxygen is 100% oxygen because the volume is entirely filled with oxygen.
An oxygen conserving device delivers oxygen to the user only when they inhale, as opposed to continuously flowing oxygen. This helps to reduce the amount of oxygen wasted during exhalation and increases the efficiency of oxygen delivery.
Most oxygen molecules are composed of two atoms of oxygen, and we frequently refer to oxygen as O2 (or O2) for this reason. Oxygen can also exist as the molecule called ozone, which is O3. Ozone is unstable, and will revert to O2 in a few minutes.
From areas of high oxygen concentration to low oxygen concentration, diffusion occurs as oxygen molecules move down their concentration gradient, from where there is more oxygen to where there is less oxygen. This process enables the cells in the body to take in oxygen and use it for cellular respiration, supporting various physiological functions.
Penguins are birds and like all birds they get oxygen by breathing air.
They breathe in oxygen like humans.
Through their beaks.
Penguins breathe in oxygen and breathe out carbon dioxide. They have this in common with all animals.
No, there is no oxygen for them.
Penguins require oxygen for respiration, so they cannot remain underwater for excessive periods of time.
Penguins have a respiratory system similar to other birds. They breathe air into their lungs, where oxygen is extracted and carbon dioxide is expelled. Penguins can dive underwater for extended periods of time due to adaptations such as increased oxygen storage capacity and efficient use of oxygen in their muscles.
Like all birds, penguins get their oxygen by breathing air. Therefor, they can't breath underwater. However, small penguins like the blue fairy penguin can hold their breath for dives that last about one or two minutes. Than they come back to the surface to breath.
Penguins use their lungs to breath.
Emperor penguins breathe through their lungs, taking in oxygen from the air and expelling carbon dioxide. When they are swimming underwater, emperor penguins can hold their breath for up to 18 minutes, utilizing their large lung capacity and efficient oxygen exchange system to dive deep for food.
No, penguins do not have blue blood. Penguins, like other birds, have red blood due to the presence of hemoglobin, which carries oxygen in their bloodstream. Blue blood is found in animals like horseshoe crabs and some mollusks due to a different type of oxygen-carrying molecule called hemocyanin.
Penguins breathe using their lungs, just like other birds and mammals. They surface to breathe in fresh air and can also absorb some oxygen through their skin when underwater. Penguins are highly adapted to diving and can hold their breath for extended periods while hunting for food.
