Diffusion.
it uses its gills
During cellular respiration, glucose gets oxidized to form carbon dioxide and water, while oxygen gets reduced to form water. Glucose loses electrons and hydrogen atoms, which are transferred to oxygen during the process, resulting in the reduction of oxygen to water.
it gets into the water simply by the oxygen and H2o (water) Toxics!
water gets dissolved into water by rushing water or rapids if there are trees or brush in the water it will help disolve the oxygen in to the water if there is a waterfall located somewhere in the stream or river that will desolve a lot of oxygen
Because the warmer the water gets the less oxygen the water contains.
Sodium burns in water as it gets reacted with the oxygen in water and yields NaOH and that is why it is stored in Paraffin.
As wer gets deeper there is less oxygen and it gets colder.
Oxygen that is dissolved in the water crossed ghe gill menbrane by diffusion. The oxygen is dissolved in the water like carbon dioxide in a beer. This oxygen is not a part of the water molecule. The oxygen in the water molecule is not available to the fish, when dosolved oxygen gets low, yhou have a fish kill.
Fish have gills- thy are similar to lungs, but water gets pumped through them. Oxygen dissolved in the water transfers (in the gills) to the bloodstream of the fish, and carbon dioxide gets flushed out.
A sponge gets its oxygen from the water. The oxygen moves from the water to the sponge by a process called diffusion. Diffusion is when molecules of a substance move from an area where they are highly concentrated (where there are a lot of oxygen molecules) to an area where they are less concentrated (where there are not a lot of oxygen molecules). Oxygen is more highly concentrated in the water then in the sponge. Therefore, the oxygen goes from the water to the sponge.
The O from H2O goes to form Oxygen as O2 which is a gas and gets mixed up in the air
Because it gets its oxygen from the water through its gills.
