Answer the following question given this paragraph: The evolution of life on Earth over the past 4 billion years has resulted in a huge variety of species. For more than 2,000 years, humans have been trying to classify the great diversity of life. The science of classifying organisms is called taxonomy. Classification is an important step in understanding the present diversity and past evolutionary history of life on Earth. Q: What is the science of classifying the many organisms on earth called? A:
OPTIONS:
- general classification
- terminology
- methodology
- taxonomy
taxonomy

Answer the following question given this paragraph: According to the kinetic theory, particles of matter are in constant motion. The energy of motion is called kinetic energy. Q: What is the energy of motion called? A:
OPTIONS:
- inertia
- harmonic energy
- stasis
- kinetic energy

Answer: kinetic energy

Question: Answer the following question given this paragraph: Keeping the rate of metabolism high takes a constant and plentiful supply of oxygen. That's because cellular respiration, which produces energy, requires oxygen. The lungs and heart of mammals are adapted to meet their oxygen needs. Q: A constant and plentiful supply of oxygen is required in order to maintain a high rate of what? A:
OPTIONS:
- digestion
- cell division
- magnesium
- metabolism
Answer: metabolism

input with options: Answer the following question given this paragraph: Acid-base reactions involve a transfer of a hydrogen ion instead of an electron. Acid-base reactions, like the one below, are also not redox reactions. Q: What is transferred in an acid-base reaction A:
OPTIONS:
- bonding ion
- friendly ion
- calcium ion
- hydrogen ion
output: hydrogen ion

Q: Answer the following question given this paragraph: Both dry and wet cells work the same basic way. The electrodes react chemically with the electrolyte, causing one electrode to give up electrons and the other electrode to accept electrons. In the case of zinc and carbon electrodes, the zinc electrode attracts electrons and becomes negatively charged, while the carbon electrode gives up electrons and becomes positively charged. Electrons flow through the electrolyte from the negative to positive electrode. If wires are used to connect the two electrodes at their terminal ends, electric current will flow through the wires and can be used to power a light bulb or other electric device. Q: Electrons flow through the electrolyte from the ________ to __________ electrode. A:

OPTIONS:
- neutral; negative
- negative; neutral
- positive; negative
- negative; positive

A: negative; positive

OPTIONS:
- atoms
- helium
- hydrogen
- element
element
