The correct answer is option C, that is, the Operons afford the organism the opportunity to simultaneously monitor the transcription of multiple genes, whose products are active in the same process.  
The genes, which correspond to a particular metabolic procedure are usually under the control of a single promoter in a bacteria. This is known as Operon that assists in monitoring the expression of genes taking part in the similar metabolic procedure.

Answer:
According to the law of conservation of energy, energy cannot be created or destroyed, although it can be changed from one form to another. KE + PE = constant. A simple example involves a stationary car at the top of a hill.
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside.  The only way to use energy is to transform energy from one form to another.
Similarly, the law of conservation of energy states that the amount of energy is neither created nor destroyed. ... For example, when you roll a toy car down a ramp and it hits a wall, the energy is transferred from kinetic energy to potential energy.

Answer
c
Explanation:
because mechanical energy has approximately 2.65% chemical energy causing it to be able to constantly change.
