Answer the following question given this paragraph: The frontal lobe is located at the front of the brain, over the eyes. This lobe contains the olfactory bulb, which processes smells. The frontal lobe also contains the motor cortex, which is important for planning and implementing movement. Areas within the motor cortex map to different muscle groups, and there is some organization to this map, as shown in Figure 35.22. For example, the neurons that control movement of the fingers are next to the neurons that control movement of the hand. Neurons in the frontal lobe also control cognitive functions like maintaining attention, speech, and decisionmaking. Studies of humans who have damaged their frontal lobes show that parts of this area are involved in personality, socialization, and assessing risk. Q: What is the bulb called in the frontal lobe that processes smells? Choices: - peripheral bulb - auditory bulb - sensory bulb - olfactory bulb A:
**Answer**
olfactory bulb

Answer the following question given this paragraph: 32.5 Fusion While basking in the warmth of the summer sun, a student reads of the latest breakthrough in achieving sustained thermonuclear power and vaguely recalls hearing about the cold fusion controversy. The three are connected. The Sun's energy is produced by nuclear fusion (see Figure 32.15). Thermonuclear power is the name given to the use of controlled nuclear fusion as an energy source. While research in the area of thermonuclear power is progressing, high temperatures and containment difficulties remain. The cold fusion controversy centered around unsubstantiated claims of practical fusion power at room temperatures. Q: What is the name given to the use of controlled nuclear fusion as an energy source? Choices: - generator power - half-life - fossil fuel - thermonuclear power A:
**Answer**
thermonuclear power

Answer the following question given this paragraph: Clearing land for agriculture and development is a major cause of habitat destruction. Within the past 100 years, the amount of total land used for agriculture has almost doubled. Land used for grazing cattle has more than doubled. Agriculture alone has cost the United States half of its wetlands ( Figure below ) and almost all of its tallgrass prairies. Native prairie ecosystems, with their thick fertile soils, deep-rooted grasses, diversity of colorful flowers, burrowing prairie dogs, and herds of bison and other animals, have virtually disappeared ( Figure below ). Q: Clearing land for agriculture and development is a major cause of what negative result? Choices: - water destruction - human destruction - mineral destruction - habitat destruction A:
**Answer**
habitat destruction
