Answer: lakes

input with options: Answer the following question given this paragraph: Bones look tough, shiny, and white because they are covered by a layer called the periosteum . Many bones also contain a soft connective tissue called bone marrow in the pores of the spongy bone. Bone marrow is where blood cells are made. Q: What layer covers the bones that make them look tough, shiny, and white? A:
OPTIONS:
- epithelium
- cuticle
- epidermis
- periosteum
output: periosteum

Q: Answer the following question given this paragraph: The standard reduction potential can be determined by subtracting the standard reduction potential for the reaction occurring at the anode from the standard reduction potential for the reaction occurring at the cathode. The minus sign is necessary because oxidation is the reverse of reduction. Ecell = Ecathode Eanode +0.34 V = E 2+ EH + /H = E 2+ 0 = E Cu. Q: The standard reduction potential can be determined by subtracting the standard reduction potential for the reaction occurring at the anode from the standard reduction potential for the reaction occurring at this? A:

OPTIONS:
- Spinner
- plasma
- electrode
- cathode

A: cathode

input: OPTIONS:
- atoms
- solutions
- molecules
- particles Now, answer this question: Answer the following question given this paragraph: A colloid is a homogeneous mixture with medium-sized particles. Examples include homogenized milk and gelatin. The particles of a colloid are large enough to reflect light, so you can see them. But they are too small to settle or filter out of the mixture. Q: A colloid is a homogeneous mixture with medium-sized what? A:
A:
output: particles

Answer the following question given this paragraph: When ordered by atomic number, the discrepancies within Mendeleev's table disappeared. Tellurium has an atomic number of 52, while iodine has an atomic number of 53. So even though tellurium does indeed have a greater atomic mass than iodine, it is properly placed before iodine in the periodic table. Mendeleev and Moseley are credited with being most responsible for the modern periodic law : When elements are arranged in order of increasing atomic number, there is a periodic repetition of their chemical and physical properties. The result is the periodic table as we know it today. Each new horizontal row of the periodic table corresponds to the beginning of a new period because a new principal energy level is being filled with electrons. Elements with similar chemical properties appear at regular intervals, within the vertical columns called groups . Q: Each new horizontal row of the periodic table corresponds to the beginning of a new period because a new principal energy level is being filled with what? A:

OPTIONS:
- protons
- photons
- neutrons
- electrons

Answer: electrons

Q: Answer the following question given this paragraph: Maintaining a high metabolic rate takes a lot of energy. The energy must come from food. Therefore, mammals need a nutritious and plentiful diet. The diets of mammals are diverse. Except for leaf litter and wood, almost any kind of organic matter may be eaten by mammals. Q: Maintaining a high metabolic rate takes a lot of what? A:

OPTIONS:
- food
- calories
- fuel
- energy

A:
energy
