What are the consequence if oxygen an carbon dioxide were absent from the earth surface?
If oxygen and carbon dioxide were absent from the Earth's surface, most living organisms would not survive as they are essential for respiration and photosynthesis. Without oxygen, aerobic organisms would suffocate, and without carbon dioxide, plants would not be able to perform photosynthesis leading to a collapse in the food chain. The Earth's atmosphere and climate would also be drastically altered without these gases.

Which 2 gases are exchanged at the surface of the air sac?
Oxygen and carbon dioxide are exchanged at the surface of the air sac. Oxygen is taken in from the air into the bloodstream, while carbon dioxide is released from the bloodstream into the air to be exhaled.
Why do raisins dance in carbon dioxide?
Raisins "dance" in carbon dioxide because the gas forms bubbles on their wrinkled surface, making them float to the top. As the bubbles burst at the surface, the raisins sink back down. This rising and sinking motion gives the illusion that the raisins are dancing in the carbon dioxide.
Why does limestone bubbles when acid is added to its surface?
Limestone contains calcium carbonate, which reacts with acid (such as hydrochloric acid) to form carbon dioxide gas. The release of carbon dioxide gas creates bubbles or fizzing on the limestone surface.
Where does the carbon dioxide pass through?
Carbon dioxide passes through the stomata, which are small openings on the surface of plant leaves that allow gases to be exchanged with the surrounding environment. This exchange of gases, including carbon dioxide and oxygen, is essential for photosynthesis and respiration in plants.
How carbon dioxide enters a leaf?
Carbon dioxide enters a leaf through small openings called stomata on the surface of the leaf. The stomata open to allow carbon dioxide to diffuse into the leaf from the surrounding air. Once inside the leaf, carbon dioxide is used during photosynthesis to make glucose and oxygen.
What happens a plant if rubisco is absent?
carbon dioxide would not be captured
Is carbon dioxide in rain water?
All rain and surface water absorbs carbon dioxide from the atmosphere.
Why does carbon dioxide escape from fizzy drinks?
Air bubbles containing carbon dioxide rise to the surface of the drink once the bubbles pop, they release the carbon dioxide.
Which 2 gases are exchanged at the surface of the air sac?
Oxygen and carbon dioxide are exchanged at the surface of the air sac. Oxygen is taken in from the air into the bloodstream, while carbon dioxide is released from the bloodstream into the air to be exhaled.
Do iPods have carbon dioxide in them?
Where there are no components, there is air when it is located on Earth's surface. Our air has some carbon dioxide in it. So there is some carbon dioxide in an ipod. It is not necessary to the function of an ipod. If you burn an ipod, some carbon dioxide will be released, since the casing has some carbon in it.
What is a predicted consequence of increased carbon dioxide concentration in the atmosphere?
A predicted consequence of increased carbon dioxide concentration in the atmosphere is an increase in global temperatures, as carbon dioxide is a greenhouse gas which captures and retains the sun's heat.
Why do raisins dance in carbon dioxide?
Raisins "dance" in carbon dioxide because the gas forms bubbles on their wrinkled surface, making them float to the top. As the bubbles burst at the surface, the raisins sink back down. This rising and sinking motion gives the illusion that the raisins are dancing in the carbon dioxide.
Which two gases are exchanged at the surface of airsack?
oxygen + carbon dioxide
Is the carbon dioxide layer also prevents the coming of the UV-rays from the sun?
No, carbon dioxide does not. it does not stop UV rays from the sun from coming to surface.
What planet has a dense carbon dioxide atmosphere and high surface temperatures?
Venus has a dense carbon dioxide atmosphere with surface temperatures that can exceed 800 degrees Fahrenheit (427 degrees Celsius).
Where is the ozone bad?
Bad ozone is the ozone present at the surface of the earth. It is because the ozone at the surface of earth acts as a air pollutant resembling like carbon dioxide, carbon monoxide, sulphur dioxide etc.
Which planet has a dense carbon dioxide atmosphere and high surface temperatures?
Venus has a dense carbon dioxide atmosphere and high surface temperatures, with an average surface temperature of about 467 degrees Celsius (872 degrees Fahrenheit). This extreme greenhouse effect is due to the trapping of heat by the carbon dioxide in the atmosphere.
