Ans.
Lac (lactose) operon in a type of bacterial operon, which shows a cluster of genes that are regulated by a single promoter. It is composed of an operator, promoter, a terminator, and three structural genes (lacA, lacY, and lacZ), which are responsible for the transport and breakdown of lactose.
The lac operon is an inducible operon as it gets activated in the presence of lactose and expressed its functional genes in the form of proteins (or enzymes) for lactose metabolism.
Thus, the correct answer to be fill in first blank is 'inducible' and in second blank is 'lactose.'
The correct answer is low precipitation.
The cause of limited water supplies is reduced precipitation or low precipitation.
Precipitation is termed as any product of condensation which is of atmospheric water vapour which falls under gravity.
Forms of precipitation can be sleet, snow, graupel, hail, drizzle, and rain.
Precipitation occurs when portion of atmosphere comes to being saturated with water vapor such that water condenses and then it precipitates.
It is the major component of water cycle and deposits fresh water to planet.
