Question

suppose that zonosemata flies whose own wings had been clipped and reattached were attacked more frequently than untreated zonosemata flies. how would this result have affected the reliability of the other experimental results?
all results for the experimental groups involving wing surgery would be invalid.
the reliability of the experimental results would not change.
all results for the experimental groups using houseflies would be invalid.
all results for the experimental groups using zonosemata flies would be invalid.

Explanation:

The question is about an experiment with Zonosemata flies and the impact of a result (clipped - reattached wing flies being attacked more) on experimental result reliability. We analyze each option:

• Option 1: Only the groups with wing surgery (clipping and reattaching) would have invalid results? No, because the issue is with Zonosemata flies' wing - related experiment, not just surgery groups in a narrow sense.
• Option 2: The reliability would not change? But if the wing - modified Zonosemata flies behave differently (attacked more), it affects the Zonosemata - related experiments, so reliability changes.
• Option 3: All results for experimental groups using houseflies? The experiment is about Zonosemata flies, so houseflies are irrelevant here.
• Option 4: If Zonosemata flies with clipped and reattached wings are attacked more (a deviation from normal), then all experimental groups using Zonosemata flies would be invalid because their behavior (related to wing experiments or other aspects) is compromised.

Answer:

D. All results for the experimental groups using Zonosemata flies would be invalid.
