<span>Ozone is simply a molecule consisting of 3 oxygen atoms, which reacts strongly with other molecules. Ozone is created in the stratosphere when high energy uv radiation causes on O2 molecule to split. The free oxygen atoms collide and react with other O2 molecules to form O3.</span>
Production is highest where the solar uv is the greatest eg near the tropics, but once created, the ozone is then circulated towards the poles by the atmosphere. The amount of ozone in the stratosphere can vary with location, season and even day to day climatic conditions.
<span>The process of ozone creation is what makes the O3 in the atmosphere very effective at shielding the Earth from harmful uv radiation, which can cause many biological problems, such as skin cancer. However, due to its high reactivity, the uv found in the tropospher at ground level can aslo be dangerous as a toxic pollutant which is harmful to plants and lung tissue, and is a major cause of smog.</span>
There are two daughter cells. The cell has split into two. The membrane has pinched together in the middle.
Hope that helped you.
Answer:
2, 3 and 5
Explanation:
Enzymes lower the activation energy, making life possible to occur as the reactions can happen quickly. But, they can be affected by temperature or pH, and they are always being constantly reused over and over in reactions.
Answer/Explanation:
CO and CO2 are both carbon poisoning. They both are odorless, colorless, and potentially deadly. But the chemical difference(extra oxygen molecule) causes it to be a different substance. CO is carbon monoxide while CO2 is carbon dioxide. CO2 is common because it is what we exhale after a breath, it is used to keep plants alive. On the other hand CO is caused by gas emissions and lack of oxygen. They may sound the same but they are just two different molecules containing the same types of atoms.
