1 Copy number variation (CNV) is a type of mutation where large chunks of DNA are inserted, repeated or lost. 2  These regions of DNA can be between 10,000 and 5,000,000 bases long. 3  Duplication of genes. 4  When there is an increase in the number of copies of a gene. 5  Deletions of large regions of the chromosome.
Microwaves are basically small (micro) waves of radio frequency energy. It cooks the food by vibration (waves) creating friction from within, thus creating heat. This is why it cooks from the inside-out as opposed to heat which must be absorbed from the outside-in. Microwaves are high energy electromagnetic waves.
Answer 1: Microwave ovens produce a type of energy that can travel through the air, called radiation. Light that comes out of light bulbs is also a type of radiation, but we can see this visible light radiation with our eyes. On the other hand, our eyes cannot detect microwaves, so we cannot see the microwave radiation shining down on our food while a microwave oven is running.
