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? A:

OPTIONS:
- hormonal, repressive, activator,
- repressive, activator, spontaneous
- transparent , activator , inducible
- repressive, activator, inducible

A: repressive, activator, inducible

input: OPTIONS:
- direction
- volume
- gravity
- velocity Now, answer this question: Answer the following question given this paragraph: In everyday conversation, to accelerate means to speed up. The accelerator in a car can in fact cause it to speed up. The greater the acceleration, the greater the change in velocity over a given time. The formal definition of acceleration is consistent with these notions, but more inclusive. Average Acceleration Average Acceleration is the rate at which velocity changes,. Q: In scientific terms, average acceleration is the rate at which what changes? A:
A:
output: velocity

Answer the following question given this paragraph: The body can also respond effectively to short-term exposure to cold. One response to cold is shivering, which is random muscle movement that generates heat. Another response is increased breakdown of stored energy to generate heat. When that energy reserve is depleted, however, and the core temperature begins to drop significantly, red blood cells will lose their ability to give up oxygen, denying the brain of this critical component of ATP production. This lack of oxygen can cause confusion, lethargy, and eventually loss of consciousness and death. The body responds to cold by reducing blood circulation to the extremities, the hands and feet, in order to prevent blood from cooling there and so that the body's core can stay warm. Even when core body temperature remains stable, however, tissues exposed to severe cold, especially the fingers and toes, can develop frostbite when blood flow to the extremities has been much reduced. This form of tissue damage can be permanent and lead to gangrene, requiring amputation of the affected region. Q: Which bone is derived from the fusion of four very small coccygeal vertebrae? A:

OPTIONS:
- cranium
- clavicle
- femur
- coccyx

Answer: coccyx

Problem: OPTIONS:
- water poisioning
- blood poisoning
- skin poisoning
- food poisoning
Q: Answer the following question given this paragraph: The organisms are bacteria called Salmonella. If the word Salmonella rings a bell, that's probably because Salmonella causes human diseases such as food poisoning. Many other types of bacteria also cause human diseases. But not all bacteria are harmful to people. In fact, we could not survive without many of the trillions of bacteria that live in or on the human body. You will learn why when you read this chapter. Q: Which disease does the bacteria salmonella cause in humans? A:
Answer: food poisoning

Answer the following question given this paragraph: Not long after Wegener's death, scientists recognized that there is convection in the mantle. Deeper material is hotter and so it rises. Near the surface, it becomes cooler and denser so it sinks. This creates a convection cell in the mantle. Q: How does deeper material cause convection in the mantle? A:

OPTIONS:
- remains stable
- folds
- sinks then rises
- rises then sinks

Answer:
rises then sinks
