☆☆☆☆☆Marine animals breathe through the nose by inhaling and exhaling. :)
Yes, it is a molecule. Its name is Oxygen gas (O2).
Just don't realease your anger on anyone, realease it to the useless paper, on the pillow, try to com yourself down.
Carbon Dioxide co2
Oxygen o2
photosynthesis is the way plants use materials to create food and oxygen. The equation is:
water + sunlight+ carbon dioxide = glucose + oxygen
respiration is the process in which plants release these products. the chemical equation is:
glucose + oxygen = energy +carbon dioxide + water
C + O2 ------> CO2 is the reaction equation. 1 mole of C + 1 mole of O2 makes 1 mole of CO2.
by the laws of thermodynamics, nothing can ever reach absolute zero. Theoretically, molecular motion would stop. They would still be molecules, they would just not move.
animals and humans breathe in oxygen and breathe out carbon dioxide. then flowers preform something called photosynthesis which is where they breathe in carbon dioxide and breathe out oxygen. then animals and us breathe in the oxygen that the flower made and it starts all over again.

Animals inhale oxygen and exhale carbon dioxide. Plants take in carbon dioxide and give off oxygen as a result of photosynthesis.
A change over time is often referred to as a gradual change.
