The lac operon is encodes multiple enzymes which catabolize lactose, for example beta-galactosidase
<h3>What is an operon?</h3>
An operon is a cluster of genes that are transcribed together to give a single messenger RNA (mRNA) molecule which which is used for the synthesis of multiple proteins.
An example of an operon is lac operon.
The lac operon is encodes multiple enzymes which catabolize lactose, for example beta-galactosidase.

Answer;
-Sensation
Sensation is the activation of receptors in the various sense organs
Explanation;
-Sensation is the activation of sensory receptor cells at the level of the stimulus. Perception is the central processing of sensory stimuli into a meaningful pattern. Perception is dependent on sensation, but not all sensations are perceived.
-Receptors are the cells or structures that detect sensations. A receptor cell is changed directly by a stimulus. A transmembrane protein receptor is a protein in the cell membrane that mediates a physiological change in a neuron, most often through the opening of ion channels or changes in the cell signaling processes.
