You spontaneously grow gills and then that works.
Expel
They take in oxygen, and expel Carbon dioxide as a waste product.
Carbon dioxide is the result of the reaction between the yeast compounds and the gluten. The heat process causes the compounds to expel the carbon dioxide, which expands more than the oxygen in the bread.
Spiracles are the mechanism through which butterflies take in oxygen and expel carbon dioxide
the answer is a vein
The roots take in water and food - the leaves expel carbon dioxide.
All animals expel carbon dioxide from their lungs during respiration. This gas is a byproduct of the metabolic processes happening within their cells and needs to be removed from the body to prevent buildup.
Plants expel oxygen as a byproduct of photosynthesis. This process takes carbon dioxide and breaks it into carbon and oxygen.
Hyenas, like all mammals, breathe in oxygen from the air and release carbon dioxide as a waste product of respiration. They have lungs that extract oxygen from inhaled air and expel carbon dioxide when they exhale.
You do not expel any gas when inhaling. Inhaling is the act of taking air in, if you mean when exhaling (breathing out) then carbon dioxide (aka CO2)
Just like you the expel a lot of carbon dioxide due to respiration.
Plants take in Carbon Dioxide and expel Oxygen as a by-product of cellular respiration. Animals take in Oxygen and expel Carbon Dioxide as a by-product of cellular respiration.
