Ans 1 - Unlike most of the other players in the orchestra, a percussionist will usually play many different instruments in one piece of music. The most common percussion instruments in the orchestra include the timpani, xylophone, cymbals, triangle, snare drum, bass drum, tambourine, maracas, gongs, chimes, celesta, and piano.

Ans 2 - Chemical Messengers: The Endocrine System Uses Hormones to Control Body Functions. Hormones regulate internal functions from metabolism and growth to sexual development and the induction of birth. They circulate through the bloodstream, bind to target cells, and adjust the function of whole tissues and organs.

Ans 3 - Noise is sound with a continuous structure. Music is composed of sounds with a fundamental frequency and overtones. Noise is composed of sounds with frequencies that range continuously in value from as low as you can hear to as high as you can hear — not necessarily at equal intensity, however.

Ans 4 - The large rear wheels of the tractor fix the driver's seat at a higher elevation which ensures good visibility of the nose of the tractor and the corners of the field it ploughs. Small tyres cost less than larger tyres, and therefore it is much cheaper to replace small tyres that the very expensive big ones!

Answer:

1. Tabla is a percussion instrument

2. Hormones are called bodys chemical messengers as the are chemical substances that carry information and instructions to a particular set of cells through the bloodstream.

3. noise is unpleasant to hear while music is pleasing to hear

4. tractors have broad rear wheels as they usually carry heavy loads thus a lot of force is acting on them, Since we know that pressure decreases when area increases thus the rear wheels are broad so as to decrease the pressure and not cause a Reardon due to the overload
