6. Suppose that a strain of bacteria has a doubling time of one hour at room temperature if a plentiful food supply is provided. a. b. C. If 10 organisms are present at the start, nd how many there will be after 0, 1, 2, hours and enter your results in a table. (2 marks) Write an algebraic expression for the number after I hours. (1 marks) Doubling times for bacteria vary according to the temperature and the strain of bacteria. Find an algebraic expression to show the growth of bacteria with doubling times of: (4 marks) iv. 2 hours. 3 hours. 30 minutes. 20 minutes. If C is the number at the start and d the doubling time, write a formula for N. the number of bacteria after 1 hours. (1 mark)
