What else can I help you with?
How do cnidarians obtain oxygen?
Cnidarians are able to absorb the oxygen they need from the surrounding water by diffusion.
What is the deffention for moat?
A large ditch surrounding the outside of a fortification, filled with water.
Where does the oxygen come from that is reacting with a piece of burning iron?
When oxygen is reacting with iron it generally comes from the air, but it can also come from oxygen disolved into water. There are other ways it can occur but I do not know these. But unless it is in a vacuum, the oxygen comes from the surrounding environment like air or water.
Why do gills do not work outside water?
Because they can only take up oxygen from water.
Where does oxygen in water come from?
Oxygen in water primarily comes from two sources: the atmosphere and photosynthesis by aquatic plants and algae. Oxygen is dissolved into water from the surrounding air, and aquatic plants and algae produce oxygen as a byproduct of photosynthesis, releasing it into the water.
Can catfish live outside?
If you mean outside of water it can for a while is kept wet catfish can live outside of water longer than any fish that is required to breath oxygen in water if you mean outside a house than of course
What is the water on the outside of a glass water called?
The water that forms on the outside of a glass of [ice] water is called condensation. It occurs because the surface of the glass is colder than the air surrounding the glass, which causes the water vapor in the air to cool and condense into a liquid on the outside of the glass.
Can an octopus breathe outside of water?
Yes, an octopus can breathe outside of water for a short period of time because they have gills that allow them to extract oxygen from the air.
Will fish die outside their habitat?
Yes, They have to water to breath. Their gills can only process oxygen thru water.
What substances come from the outside of photosynthesis?
sunlight is the substance that comes in from the outside
Do hydras breathe with gills?
Hydras respirate via diffusion, oxygen in the comparatively oxygen-rich surrounding water passes through their epidermis to their comparatively oxygen-deficient internals. They do not breathe at all.
Why don't droplets of water form outside a glass of hot water?
temperature of the hot water combined with that of its container is higher than the ambient temperature and when the surrounding air strikes the container, the temperature of the air increase and this increases the vapour state of the air. note, for water to form around the outside of the hot water glass, the temp of the water must be lower than the temp of the surrounding air (condensation).
