Question

question 13 8 parts -- of 4 points suppose the sub - hypothesis that wing waving alone reduces predation by jumping spiders was supported by the zonosemata experiment. what results would have supported that sub - hypothesis? zonosemata flies with housefly wings are attacked less frequently. untreated zonosemata flies are attacked less frequently. zonosemata flies with their own wings cut and reglued are attacked less frequently. houseflies with zonosemata wings are attacked less frequently. part h (8 of 8)

Explanation:

To support the sub - hypothesis that wing waving alone reduces predation by jumping spiders, we need to look at an experimental setup where the key factor is wing waving. Let's analyze each option:

• Option 1: Zonosemata flies with housefly wings are attacked less frequently. Housefly wings don't wave like Zonosemata wings. If these flies (with housefly wings, so no Zonosemata - style wing waving) are attacked less, it doesn't support that wing waving alone reduces predation.
• Option 2: Untreated Zonosemata flies are attacked less frequently. This doesn't tell us about the effect of wing waving alone, as "untreated" doesn't isolate the wing - waving factor.
• Option 3: Zonosemata flies with their own wings cut and reglued. When we cut and reglue their wings, we are mainly testing the effect of wing waving (since the wing structure is still Zonosemata - like, and the act of cutting and regluing might not change the wing - waving ability significantly, or we can assume that the wing - waving is still the key factor here). If these flies are attacked less frequently, it suggests that wing waving (from their own wings) is reducing predation.
• Option 4: Houseflies with Zonosemata wings. Houseflies don't typically wave their wings like Zonosemata flies. So if houseflies with Zonosemata wings are attacked less, it's not clear if it's the wing waving (since houseflies don't wave wings like Zonosemata) or the wing structure that is causing the reduced predation.

Answer:

C. Zonosemata flies with their own wings cut and reglued are attacked less frequently.
