It is possible for a repressor to negatively regulate the expression of an operon because: A. the repressor-binding site overlaps the promoter site of the operon, allowing it to physically block the binding of RNA polymerase. B. the repressor induces the expression of the inducer by binding to the promoter that comes before the inducer gene. C. the repressor-binding site on the DNA overlaps with the translation start site, thereby preventing the transcription. D. one of the structural genes expressed in the operon negatively regulates the repressor. E. the repressor physically blocks where the activator should be binding on the operator region.

Chinese privet is a plant that is native to china. over 150 years ago, chinese privet was introduced to the united states as a fast-growing shrub that serves as an excellent privacy hedge. with no natural herbivore, chinese privet quickly established itself and spread in natural areas throughout the southeast and eastern seaboard of the united states. its dominance in these areas has jeopardized the survival of native plant species. chinese privet provides evidence that introducing non-native organisms can cause environmental damage integrated pest management strategies will not decrease chinese privet populations american gardeners can easily control the spread of chinese privet non-native plant species have type i survivorship curves
