25 POINT!!

Which of the following correctly explains how some bacterial infections can become difficult to treat with antibiotics?

The bacteria form flagella or cilia to move to new locations where they are protected.
The bacteria do not have the appropriate protein or lipid receptors on their cell walls.
The bacteria produce new types of enzymes that preserve and copy the genetic material.
The bacteria develop resistant endospores and pass their immunity on to others.

Which part of cellular respiration must occur before any of the other steps can occur

Keeping in mind the life cycle of bacteriophages, consider the following problem: during the reproductive cycle of a temperate bacteriophage, the viral dna inserts into the bacterial chromosome where the resultant prophage behaves much like a trojan horse. it can remain quiescent, or it can become lytic and initiate a burst of progeny viruses. several operons maintain the prophage state by interacting with a repressor that keeps the lytic cycle in check. insults (ultraviolet light, for example) to the bacterial cell lead to a partial breakdown of the repressor, which in turn causes the production of enzymes involved in the lytic cycle. as stated in this simple form, would you consider this system of regulation to be operating under positive or negative control?
