Worked Solution & Example Answer:Francesco Redi challenged the idea that maggots arose spontaneously from rotting meat - HSC - SSCE Biology - Question 10 - 2020 - Paper 1
Step 1
A. The sealed jar improves the validity of the experiment.
Answer
In the context of Francesco Redi's experiment, the sealed jar indeed enhances the validity by preventing external factors, like flies, from contaminating the setup. This allows for a clearer observation of whether maggots arise from the meat.
Step 2
B. The independent variable is whether the meat spoils or not.
Answer
The independent variable in this experiment is not whether the meat spoils but the different conditions under which the meat is placed (sealed, gauze-covered, or open jars). The spoilage would be a result influenced by these conditions.
Step 3
C. The use of three jars improves the reliability of the experiment.
Answer
Using three jars does improve reliability as it allows for comparisons across different conditions. Multiple trials contribute to consistency in the results, enhancing the overall conclusions drawn from the experiment.
