Answer:
Based on David's experiment, he can answer question C) if mosquitoes prefer pond water over muddy water to lay eggs.
Step-by-step explanation:
By pouring equal quantities of pond water and muddy water into identical containers and observing which container has a higher presence of mosquito larvae after two days, David can determine whether mosquitoes prefer pond water over muddy water for laying their eggs. If the container with pond water has a higher presence of mosquito larvae, it would suggest that mosquitoes prefer pond water over muddy water for laying their eggs. Conversely, if the container with muddy water has a higher presence of mosquito larvae, it would suggest that mosquitoes prefer muddy water over pond water for laying their eggs.
The other questions listed - A) if mosquito larvae take one day to come out of eggs in pond water, B) if mosquitoes lay more eggs in the evening than in the morning, and D) if mosquito larvae prefer to stay near the surface of water - cannot be answered based on the experiment described, as they are not related to the specific variables that were manipulated and measured in the experiment.
