the number of bacteria in millions in a petri dish t seconds after an antibiotic is added is given by the function b(t) Assume b(t) is an exponential function first point (1,12) second point (2,2) What is the 1 unit growth factor? what is the 1 unit percent change? How many bacteria in millions are there in the petri dish at the moment the antibiotic is added? Find the function of B(t) How long does it take the number of bacteria to decrease by 50%? include units

Suppose ?(?) represents the number of bacteria in a dish t hours after the start of a lab experiment. a) Interpret the meaning of ?(20) = 100 100 is the average rate of change in the number of bacteria after 20 hours. 100 is the rate of change in the number of bacteria after 20 hours. After 20 hours, there are 100 bacteria in the dish. 100 is the total change in the number of bacteria between the first hour...

In an experiment, cells were growing in a Petri dish that had been coated with Extra-cellular matrix (ECM) components. A peptide added to the dish caused the cells to detach from the ECM on the dish surface. The peptide was a disintegrin. (a) From the statements below, which one best explains the molecular details of why the cells detached? [ Select ] ["i", "ii", "iii"]...
