Sample Questions
Choose an answer and explore the explanation to see how practice works.
A town monitors a lake after heavy spring rains. Nitrate levels rise from 1 mg/L to 8 mg/L, algae cover much of the surface two weeks later, and dissolved oxygen falls overnight before a fish kill. Which explanation best links these observations?
A cart rolls along a track. A motion sensor shows its position changes from 0 m to 2 m to 4 m to 6 m at 1-second intervals. What claim is best supported by the data?
A nerve signal reaches the end of one neuron. Chemicals are released into a tiny gap and bind receptors on the next neuron, starting a new signal. What structure is being crossed?
A fossil shell species is found in rock layers at several sites. The species lived for a short geologic time but was widespread in shallow seas. How can this fossil be most useful?
A cook leaves a metal spoon and a wooden spoon in the same pot of hot soup. After two minutes, the metal handle feels much hotter than the wooden handle. Which explanation best fits the observation?
