Does atmospheric oxygen increase after the evolution of photosynthetic prokaryotes?
Yes, as oxygen is one of the products of the photosynthetic process. Water is " cracked " to provide electrons for the chlorophyll pigment as a replacement process and the oxygen is released from H2O and goes back into the atmosphere through the stomata.
What does air go through?
Air goes through a process called respiration where oxygen is taken in and carbon dioxide is expelled. This process occurs in the lungs where oxygen is absorbed into the bloodstream and circulated throughout the body to provide energy to cells. Carbon dioxide is then released as a waste product.
How does oxygen enter your body?
Oxygen (O2) enters your body through breathing air, which contains oxygen in it. This oxygen goes into your lungs where it is put into the bloodstream, supplied to cells in your body, returned to the lungs as carbon dioxide (CO2), and exhaled through the lungs.
What is oxygen-carbon dioxide cycles?
The oxygen-carbon dioxide cycle is the process by which carbon dioxide is converted into oxygen through photosynthesis by plants, and then oxygen is converted back into carbon dioxide through respiration by living organisms. This cycle is essential for maintaining the balance of oxygen and carbon dioxide in the atmosphere, which is crucial for sustaining life on Earth.
What organ converts blood from oxygen-rich to oxygen-poor?
oxygen rich blood gets pumped out of your heart to your arteries which carries the blood to your muscles. then your muscles use the oxygen. oxygen poor blood goes into your veins to go back into your heart. then it goes through a cycle that takes your blood to your lungs, to get oxygen. this process is repeated.
What makes the oxygen unclean?
When it goes through a body and comes out
When carbon dioxide is taken into a plant what molecule does the carbon eventually become a part of?
Carbon goes to CarbohydrateOxide goes to Oxygen
How do fish take in oxygen?
The fishes gills are like filters. when water goes in a fish's mouth, it goes through the gills, which filter out the oxygen.
By which process is oxygen cycled through the biosphere?
photosynthesis
Through what process do do plants produce oxygen?
respiration
What is the process through which oxygen weathers a rock?
Oxidation
How earthworms get oxygen to their. Cells?
Oxygen dissolves on the mucus of their skin and goes into their cardiovascular system. And since it goes through the mucus of their skin they have to stay moist.
