          Molting is the process by which insects grow. It allows the body of the insect to expand under controlled

          with molting, the process of shedding and replacing the rigid exoskeleton.This exoskeleton is basically their
          underlying bone structure that is located on the outside of their bodies with corresponding organs and muscles
          located underneath this hard shell. Ecdysone is the major steroid hormone in insects and plays essential roles
          in coordinating developmental transitions such as larval molting.

         If the filament current in a Coolidge tube is increased by increasing the voltage in the filament circuit, more
         electrons are emitted per unit time. This result in an increase in the number of X photons emitted per unit time
         and hence the intensity of X-rays is increased.

          COUNT – Returns a count of rows over a result set
          FIRST – Returns the first value of a column in a result set
          LAST – Returns the last value of a column in a result set

     a) 5 dB

           The lowest possible sound that can be heard is called the threshold of hearing. The threshold of hearing is 
           assigned a sound level of 0 decibels (abbreviated 0 dB). The sound level at the  threshold of hearing 
           corresponds to an intensity of
1*10-12 W/m2. Intensity of sound is measured in Watts per square meter.
