The given statement is true.
Some of the health science sites may restrict employees from wearing perfumes or other fragrances because the chemicals in the fragrances can stimulate reactions ranging from headaches to palpitations of heart in some of the individuals who are sensitive to them, making it tough for them to work efficiently.
With time, the individuals getting exposed to the chemicals present in the fragrances become more sensitized to them to the point that they can no longer tolerate any more exposure. This can initiate breathing issues, nausea, sneezing, disorientation, and in extreme situations, they can even go into shock.

Answer:
Since there is presence of excess tryptophan, the trp operon will be switched off, since the bacterial need not to synthesize.
Explanation:
Understand the following.
The trp operon is a group of gene that encode biosynthetic enzymes for the amino acid tryptophan.
The transcription gene in the operon is switched off when the tryptophan is in excess but is switched on by the bacterium when the tryptophan is low, so that more tryptophan can be produced.
