<h3>What are Antibodies ?</h3>
When the immune system of the body recognises dangerous compounds, known as antigens, it produces a protein called an antibody. Microorganisms (bacteria, fungi, parasites, and viruses) and chemicals are examples of antigens.

Hurricanes are caused by warm and cold air meeting in the air which causes spinning in the clouds, short term impacts are damaged property, power lines and flooding long term impacts are damaged environment(it takes a while for it to go back to normal). Tornadoes are caused by warm air meeting cold air and causing the cloud to spin and touch the ground. Short term impacts are damaged crops, plants, and trees.
