<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>
Answer:
B and D
Explanation:
Biodiversity comes from having multiple types of organisms. This also allows different organisms to eat and create nutrients that is needed by all other organisms in the ecosystem.
Answer:
All of the above.
Explanation:
Allosteric protein may be defined as the protein that has multiple ligand sites and binds to the site other than the active site. Allosteric protein is involved in the regulation of metabolic pathways of the body.
Allosteric protein does not follow the Michaelis-Menton kinetics. These proteins are multisubunit protein and has the different binding sites for the effector as well as substrate molecule. These proteins are present at the committing steps of the metabolic pathways.
Thus, the correct answer is option (e).
The best answer is c - a hickory tree.
An organism is defined as a living thing which can function on its own. It has interdependent parts and is capable to some degree of responding to stimuli, can reproduce, grow and develop and maintain homeostasis. Plants are organisms because they fulfill all these characteristics.
On organism is made up of one or more cells. If it has only one cell it is called a unicellular organism and if it has more than one cell it called a multi cellular organism.
