Mutation is a change in DNA, the hereditary material of life. An organism's DNA affects how it looks, how it behaves, and its physiology  all aspects of its life. So a change in an organism's DNA can cause changes in all aspects of its life.
continuously variable transmission (CVT)=An automatic transmission that can change seamlessly through an infinite number of effective gear ratios between maximum and minimum values. Automatic transmission= Automatically change gear ratios as the vehicle moves, freeing the driver from having to shift gears manually.
Capacitor Voltage Transformers (CVT), are used for voltage metering and protection in high voltage network systems. They transform the high voltage into low voltage adequate to be processed in measuring and protection instruments secondary equipment, such as relays and recorders). A Voltage Transformer (VT) isolates the measuring instruments from the high voltage of the monitored circuit.
