Exercise 1 Questions 1. What patterns do you observe based on the information in Table 4? The closer the pH is too neutral (7pH) the higher the number of colonies that are present. 2. Develop a hypothesis relating to the pH level of the culture media and the number of microbial colonies observed in each culture. The number of colonies increase when pH scale is closer to neutral. 3. What would your experimental approach be to test this hypothesis? Analyse the number of colonies in different pH levels. 4. What would be the independent and dependent variables? IV: pH of the solution DV: Number of colonies 5. What would be your control?
