Question

Based on your hypothesis, you predict that the chemical isolated from the fungus will successfully kill cancer cells. To test this prediction, you design the following experiment. You isolate cancerous cells from the colon of a patient from North Carolina and culture (grow) the cells in your lab. You divide the cultured cells into four separate culture dishes. You treat two of the dishes with the fungus chemical and the other two with a control solution that does not contain the chemical. Over the next ten days, you collect data on the percentage of cells that remain alive in each culture dish. This graph displays the data you collected. Determine which statements are supported by the data in the graph. Drag each statement into the appropriate bin.

Answer 1

To validate a hypothesis that a fungus chemical can kill cancer cells, an experiment similar to that of Fleming's with Penicillium would involve treating cell cultures and observing their survival. This process involves conducting an experiment as part of the scientific method, where a hypothesis, such as 'Mold kills bacteria', is tested through observation and data analysis.

Step-by-step explanation:

To test the hypothesis that a chemical isolated from a fungus can kill cancer cells, a series of experiments can be designed. These experiments would involve growing cancer cells and treating them with either the fungus chemical or a control solution. For instance, similar to Fleming's experiments with Penicillium, cancer cells could be divided into different dishes and treated to observe the effects of the chemical compared to the control. The experiment would involve monitoring these cell cultures over a certain period, noting the percentage of cells that survive in each dish.

Fleming's approach to testing his hypothesis involved introducing mold to bacterial colonies and observing the presence of a clearing, indicative of bacterial death due to the mold. This step where Fleming introduced mold to bacteria after growth in broth is an example of the experimentation phase in the scientific method. A suitable hypothesis expressed by Fleming's observation could be that 'Mold kills bacteria'.

Similarly, in a fungus chemical experiment, the results would show whether there is an anti-cancer effect by comparing the survival of cancer cells in the treated vs. control dishes. These comparisons help ascertain if the experimental setup is valid and whether there are any significant differences that support the initial hypothesis.
