Answer:

Please see below

Step-by-step explanation:

The presence of the following is a necessary requirement for producing beta galactosidase: lactose, lacI+, lacZ+, and lacO+. Since there is a constitutive operator present, it will not let the repressor protein bind, beta galactosidase production will constitutive as well - though at a lower rate because the other operator is wildtype.
