Question

what is rancidity? write two ways by which iteste can be prevented​

Answer 1

People have looked up at birds for years and they have inspired us to fly. Airplanes have wings, just like birds. They also have a light skeleton (or framework) to decrease their weight, and they have a streamlined shape to decrease drag. The big difference is that airplanes do not flap their wings.
