Answer:
a. The production of enzymes that allow for the fermentation of the sugar lactose when it becomes available in the culture medium
Explanation:
When an operon that is normally not expressed and remains inactive since a repressor molecule is attached to its operator, it is said to be an inducible operon. The transcription of the operon is activated when an inducer binds to the repressor. This binding does not allow the repressor protein to bind to the operator. The operon is transcribed by RNA polymerase.
When lactose is present in the medium, the lac operon is expressed. Some of the lactose is converted into allolactose. Allolactose binds to the repressor and makes it unable to bind to the operator. This makes it an inducible operon.
Answer:
d. cerebrum, cerebellum, and brain stem is the correct answer.
Explanation:
The three major parts of the brain are:
- Cerebrum: It the largest part of the brain. It is made up of the right hemispheres and left hemispheres. It is responsible for voluntary activity, sensory functions, and neural functions.
- Cerebellum: It the region found below the cerebrum and back the brainstem, the function of the cerebellum is to regulate the motor and voluntary movements.
- brainstem: It controls the basic function of the body such as heart rate, breathing, blood pressure, swallowing, and consciousness.
