The development of specific plant structures in particular locations is called pattern formation. events in a plant's early development play an important role in establishing the plant's form. complete the flowchart about pattern formation in plants beginning with the normal division of a plant zygote (fertilized egg). drag the labels to their appropriate locations on the flowchart. not all labels will be used.

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?
