which best describes one way that the scientists’ findings support the argument that information lobsters receive through sensory receptors can cause immediate changes in behavior?
○ a. by showing that lobsters avoid chemical cues from predators and diseased lobsters at both normal and high salt concentrations
○ b. by showing that lobsters were more likely to avoid shelters with cues from predators when the salt concentration was normal, but not when it was high
○ c. by showing that lobsters were more likely to avoid shelters with cues from diseased lobsters when the salt concentration was high, but not when it was normal

Explanation:

The question asks how the data supports that sensory input (chemical cues) causes immediate behavioral changes (shelter avoidance). The table shows lobsters avoid shelters with predator/diseased cues at both salt concentrations, linking sensory reception to behavior. Option A states lobsters avoid these cues at normal and high salt, matching the data. Other options contradict the table (e.g., B says no avoidance at high salt, which is false).

Answer:

A. by showing that lobsters avoid chemical cues from predators and diseased lobsters at both normal and high salt concentrations
