Problem: OPTIONS:
- trichina
- stibium
- spirogyra
- hydrargyrum
Q: Answer the following question given this paragraph: In this image, you see small pools of elemental mercury. The Latin name for mercury is hydrargyrum, a compound word meaning "water-silver" (hydr- = water, -argyros = silver), since it is liquid like water but shiny like silver. Mercury is the only pure metal that exists as a liquid at room temperature. Q: What is the latin name for mercury? A:
Answer: hydrargyrum
Problem: OPTIONS:
- flagella
- mucosa
- alveoli
- villi
Q: Answer the following question given this paragraph: The jejunum is the second part of the small intestine. This is where most nutrients are absorbed into the blood. The inside surface of the jejunum is covered with tiny projections called villi (villus, singular). The villi make the inner surface of the small intestine 1000 times greater than it would be without them. You can read in Figure below how villi are involved in absorption. Q: The inside surface of the jejunum is covered with tiny projections called what? A:
Answer: villi
Problem: OPTIONS:
- chemical energy
- solar energy
- thermal energy
- mechanical energy
Q: Answer the following question given this paragraph: Electrical motors change electrical energy into mechanical energy. The motor consists of an electrical circuit with part of the wires inside a magnetic field. This can be seen below. Positive charges move through the circuit in the direction of the light purple arrows. When the charges move up through the part of the coil that is right next to the north pole, the right hand rule tells us that the wire suffers the force, F , pushing the wire in the direction of the blue arrow, toward the back of the sketch. On the other side of the coil, where the charges are moving down through the field, the right hand rule shows the force would push this side of the coil toward the front. These two forces are working together, rotating the coil in the direction of the circular red arrow. Q: An electrical motor changes electrical energy into what? A:
Answer:
mechanical energy
