In 1 -Laboratory a colony of viruses is being observed to grow at a rate that is proportional to the number of cells present. At present, there were 5 cells. After 60 minutes, the colony of the viruses increases to 1000. Assuming that the growth rate of the viruses is constant, how many will there be after 1 day?The number of bacteria in a laboratory is decreasing exponentially. There are 10000 bacteria in the laboratory after 1 hour and 7500 bacteria after 10 hours. How many bacteria are there initially? After how many hours will there be 500 bacteria in the laboratory
