Final answer:
If meat in the freezer has maggots, it must be discarded for health safety. Francesco Redi's experiment in 1668 disproved spontaneous generation, showing maggots arise from flies' eggs. Proper food storage and hygiene are essential to prevent such occurrences and infections like ringworm.
Step-by-step explanation:
When faced with the situation where meat in the freezer has maggots, it is crucial to discard the meat immediately. Maggots are the larvae of flies, and their presence indicates that flies had access to lay eggs on the meat. This outcome speaks to the importance of properly sealing and storing food to prevent such infestations. The Italian physician Francesco Redi's experiment in 1668 is a foundational study in biology that disproved the idea of spontaneous generation, demonstrating that maggots come from fly eggs and not from the meat itself. Redi's work showed that by covering meat or sealing it properly, one could prevent the development of maggots, as only the uncovered meat produced maggots while the covered and sealed containers did not.
In relation to health concerns like Sarah's 'worm,' or ringworm, it highlights how living organisms such as parasites and fungi are spread through contact. Ringworm, which is a fungal infection of the skin, spreads through direct contact with an infected person or animal, or by touching contaminated objects and surfaces, and being vigilant about hygiene can help prevent such infections.
