Q: Q: Which bone is derived from the fusion of four very small coccygeal vertebrae? Read this paragraph and choose the correct option from the provided answers: 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. Choices: - cranium - clavicle - femur - coccyx A:
A: coccyx

Q: Q: What term is used to describe the line of latitude right in the middle of the planet? Read this paragraph and choose the correct option from the provided answers: Lines of latitude circle around Earth. The equator is a line of latitude right in the middle of the planet. The equator is an equal distance from both the North and South Pole. If you know your latitude, you know how far you are north or south of the equator. Choices: - Prime Meridian - orbital - pole - equator A:
A: equator

Q: Q: The differing glycosidic linkages in starch and cellulose give the two molecules what kind of distinct shapes? Read this paragraph and choose the correct option from the provided answers: Choices: - square - one-dimensional - diamond - three-dimensional A:
A: three-dimensional

Q: Q: What kind of bases completely dissociate in water, releasing all hydroxide anions into the solution? Read this paragraph and choose the correct option from the provided answers: Strong bases completely dissociate in water, releasing all hydroxide anions into the solution. The most common strong bases are soluble metal hydroxides. Weak bases partially deprotonate water to form small amounts of hydroxide and the protonated base. Choices: - unusual - weak - whole - strong A:
A: strong
