We are unable to extract oxygen from water
Fish have gils, that's what makes them breathe underwater.
No. Monkeys are mammals, so they have lungs, which cannot filter water. They can hold their breath underwater, though.
fish breath under water because in water oxygen is mixed.
When lobsters are underwater they breath in oxygen, when they come above water they breath out carbon dioxide.
Humans cannot breathe underwater because our lungs do not have enough surface area to absorb enough oxygen from water, and the lining in our lungs is adapted to handle air rather than water.
If a baby is born underwater using the birthing method known as "Water birth" (a method of giving birth, which involves immersion in warm water.) it can survive underwater momentarily until you take it out of the water and takes its first breath. This is not to say that a baby born in water becomes capable of extended survival underwater like mythical mermaid.
Breathing underwater can be difficult if you do not have the right equipment. A snorkel can help you to breath or you could use a scuba diving mask with oxygen.
Yes there is air underwater. Water is a mix of Hydrogen (H) and Oxygen (O). Hence the name 'H2O'. Hope I helped. (also, fish filter the oxygen through their gills to breath.)
Holding your breath underwater is when your head/face is underwater and you do not breath.
Fish breathe underwater using their gills. As water passes over their gills, oxygen is absorbed from the water and carbon dioxide is released. This process allows fish to extract oxygen from the water and breathe efficiently.
Seals are able to hold their breath for long periods of time while underwater by slowing their heart rate and reducing blood flow to non-essential organs. They have a high oxygen storage capacity in their muscles and blood, allowing them to stay submerged for extended periods. They also have adaptations such as efficient lungs and a high concentration of myoglobin in their muscles to help them extract oxygen from the water.
