Answer:
b. The two bacterial strains have different phenotypes.
Explanation:
In genetics, the trait that is expressed is often referred to as the dominant trait and it can also be expresssed phenotypically.
Since one of the bacteria produces the inducer, it therefore means that bacteria has the dominant strain for the regulatory inducer while the other bacteria might have the strain but since it is not expressed phenotypically, it is as a result not dominant.
Phenotype refers to the physical appearance of an organism as a result of the interaction of its genes with the environment. Examples of phenotypic expresssions are hair colour, skin colour, height, etc.

Step 1-
Your diaphragm moves down as it contracts. Your ribs move outward. These movements make the space inside the chest larger.
Step 2-
Air rushes in through the nose and mouth and passes through the throat. Air then moves past the epiglottis which is open into the trachea.
Step 3
Air moves into your bronchi. The bronchi branch out and end in tiny air sacs, called alveoli.
Step 4
<span>Air moves into your alveoli. Oxygen moves through the walls of alveoli and capillaries, entering the blood.</span>
Step 5
Carbon dioxide moves from the blood through the walls of capillaries and alveoli in order to be expelled by the lungs.
Step 6
Your diaphragm moves up as it relaxes. Your ribs move inward. These movements make the space inside the chest smaller.
Step 7
<span>Your lungs are squeezed and air is pushed out of the alveoli. The air travels back through your bronchi, trachea, and nose and mouth.</span>
