Q: Answer the following question given this paragraph: 16.2 Prokaryotic Gene Regulation The regulation of gene expression in prokaryotic cells occurs at the transcriptional level. There are three ways to control the transcription of an operon: repressive control, activator control, and inducible control. Repressive control, typified by the trp operon, uses proteins bound to the operator sequence to physically prevent the binding of RNA polymerase and the activation of transcription. Therefore, if tryptophan is not needed, the repressor is bound to the operator and transcription remains off. Activator control, typified by the action of CAP, increases the binding ability of RNA polymerase to the promoter when CAP is bound. In this case, low levels of glucose result in the binding of cAMP to CAP. CAP then binds the promoter, which allows RNA polymerase to bind to the promoter better. In the last examplethe lac operontwo conditions must be met to initiate transcription. Glucose must not be present, and lactose must be available for the lac operon to be transcribed. If glucose is absent, CAP binds to the operator. If lactose is present, the repressor protein does not bind to its operator. Only when both conditions are met will RNA polymerase bind to the promoter to induce transcription. Q: What are the three ways to control the transcription of an operon? Choices: - hormonal, repressive, activator, - repressive, activator, spontaneous - transparent , activator , inducible - repressive, activator, inducible A:
A: repressive, activator, inducible

Q: Answer the following question given this paragraph: Aquatic plants are plants that live in water. Living in water has certain advantages for plants. One advantage is, well, the water. There's plenty of it and it's all around. Therefore, most aquatic plants do not need adaptations for absorbing, transporting, and conserving water. They can save energy and matter by not growing extensive root systems, vascular tissues, or thick cuticles on leaves. Support is also less of a problem because of the buoyancy of water. As a result, adaptations such as strong woody stems and deep anchoring roots are not necessary for most aquatic plants. Q: What kind of plants do not need adaptations for absorbing, transporting, and conserving water? Choices: - desert plants - normal plants - terrestrial plants - aquatic plants A:
A: aquatic plants

Q: Answer the following question given this paragraph: One of the two generations of a plant's life cycle is typically dominant to the other generation. Whether it's the sporophyte or gametophyte generation, individuals in the dominant generation live longer and grow larger. They are the green, photosynthetic structures that you would recognize as a fern, tree, or other plant (see Figure below ). Individuals in the nondominant generation, in contrast, may be very small and rarely seen. They may live in or on the dominant plant. Q: Which generation of a plant is generally larger and longer-lived? Choices: - main generation - effective generation - alpha generation - dominant generation A:
A: dominant generation
