Growth of a bacteria population \( B(t) \) (in millions), at time \( t \) (hours), follows the logisic growth \[ B(t)=\frac{4}{1+7 e^{-t}}, \quad t \geq 0 \] (a) Sketch the graph of the bacteria population verses time, for the first eight hours. (b) What is the initial population size? (d) What value does the bacteria population approach after large time?

Question 12 2024: Canada has reported one case of Avian Influenza H5N1 in a teenager which did cause serious infection. Is this the same strain genetically identical to the strain causing human infections in California?
