If GFR is over 90, the kidneys are healthy and functioning normally. A kidney score of 60-89 means the person should be monitored, and if GFR scores falls to less than 60 for a three-month period, that is an indicator of chronic kidney disease.
Posted on. (Answer #2). Sound is a form of mechanical energy because the source of sound is vibration. Mechanical energy consists of gravitational potential energy and kinetic energy. Vibrating particles have kinetic energy which is a form of mechanical energy.osted on. (Answer #2). Sound is a form of mechanical energy because the source of sound is vibration.

Sound is the result of particles moving around and therefore having kinetic energy. It is a form of wave, somewhat like light.In space, you can't have sound because th â¦ ere is no particles to transmit this energy.eat energy is a form of kinetic energy because heat is related to  the motion of particles. This means heat is a form of kinetic  energy. Adding heat energy to an object ma â¦ kes it hotter and causes  its particles to move faster.
