Answer:
one thing that can catch in fire easily.
I think the effect would be that the lactose transport will decrease. When glucose levels are high inside the bacteria, it leads to inhibition of adenylyl cyclase and lactose permease, therefore cAMP levels are low and lactose can not be transported within the bacteria. Once the glucose is used up, the second preferred source of carbon is lactose, thus absence of glucose will switch off the catabolite repressor.
I would think b but I’m not very sure
