D. The repressor is freed from the operator when lactose is present.
Think of a bacteria that comes into contact with some lactose sugar in milk. Normally it's not in milk, so the gene is repressed (prevented) from making the lac enzyme (which digests lactose). Now when it comes across some milk, it wants to make as much lac as possible to eat up all the lactose.
FYI: trp for tryptophan works the exact opposite with repressor blocking when trp IS PRESENT.

How are mean and median alike?how are they different?
Vlada [557]

Answer:

Mean is the average you'll get when you add all your numbers then divide by the number of numbers you have. On the opposite side, median is the middle number within your list of numbers. If there isn't a middle number, take the two middle numbers and add them. Now, for how they are alike, I'm not so sure :'), but my closest guess would be they are fairly close together.

Sorry it's so long, hope I helped you :')
