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? Choices: - cranium - clavicle - femur - coccyx A:
coccyx
Answer the following question given this paragraph: The current produced by electromagnetic induction is greater when the magnet or coil moves faster, the coil has more turns, or the magnet is stronger. If the magnet or coil is moved back and forth repeatedly, alternating current is produced. Q: Alternative current is produced when a magnet or coil does what? Choices: - moves in circles at faster rates - moves at faster velocities - moves up and down repeatedly - moves back and forth repeatedly A:
moves back and forth repeatedly

Q: What helps regulate the production of urine? Choices: - the temporal gland - the discrete gland - the fetal gland - the pituitary gland A:
A: the pituitary gland
Question: Answer the following question given this paragraph: Good conductors have large numbers of free charges in them. In metals, the free charges are free electrons. Figure 20.6 shows how free electrons move through an ordinary conductor. The distance that an individual electron can move between collisions with atoms or other electrons is quite small. The electron paths thus appear nearly random, like the motion of atoms in a gas. But there is an electric field in the conductor that causes the electrons to drift in the direction shown (opposite to the field, since they are negative). The drift velocity v d is the average velocity of the free charges. Drift velocity is quite small, since there are so many free charges. If we have an estimate of the density of free electrons in a conductor, we can calculate the drift velocity for a given current. The larger the density, the lower the velocity required for a given current. Q: Why is the drift velocity negligible? Choices: - shows free charges - less free charges - need free charges - many free charges A:
Answer: many free charges
