Question

step 5: conclusion: scientific conclusion to the original question: describe the relationship between the investigation and the characteristics of life. the answer will be assessed on the following: accurate, specific, scientific, and thorough claim: create a one - sentence answer for your question at the beginning of the investigation (#1). (no because) yes bacteria and fungus spontaneously arise from non - living material evidence: list observations / data that support your answer closed tube (tube a) = mold in the test tube, oil and water separates, kinda cloudy open tube (tube b) = mold in the test tube, oil separates from the water, has a film on top. reasoning: shows how and why the data connect to/or support the claim. provides the justification for why this evidence is important to the claim. (“because”) **includes one or more scientific principles that are important to the claim and evidence. (scientific vocabulary, characteristics of life) bacteria and fungus spontaneously arise from non - living material is supported by the evidence of mold presence in both the closed and open test tubes. however, this experiment has limitations and further investigation with proper controls (like sterilization) would be needed for a more conclusive result step 6: value beyond school how do these findings from this investigation apply to food safety and cooking? what measures do we take to keep food safe and preserved (boil, lids, refrigeration, cabinets)? research and identify 3 ideas.

Explanation:

The investigation shows mold presence in both closed and open test - tubes, which may seem to support the idea of bacteria and fungus arising from non - living material. For food safety, proper sterilization (like boiling), using lids to prevent contamination, refrigeration to slow microbial growth, and storing food in clean cabinets are important. Boiling kills most microbes, lids prevent airborne contaminants, and refrigeration lowers the metabolic rate of microbes.

Answer:

1. Boiling: Kills most microorganisms present in food, reducing the risk of spoilage and food - borne illness.
2. Lids: Create a barrier that prevents airborne contaminants, such as mold spores and bacteria, from reaching the food.
3. Refrigeration: Lowers the temperature, which slows down the growth and metabolic activities of microorganisms, thus preserving food for a longer time.
