To begin a bacteria study, a petri dish had 1500 bacteria cells. Each hour since, the number of cells has increased by 6.3%. Let t be the number of hours since the start of the study. Let y be the number of bacteria cells. Write an exponential function showing the relationship between y and t.

When a petri dish was inoculated from liquid culture, the colony on the petri dish arose from ------ O A cells that were alive in liquid culture cells that were dead in liquid culture OB o c cells that were lysed in liquid culture cells that cannot divide in liquid culture OD

in an experiment with a cell line, 30% of the cells in a petri dish divide into two every hour and 10% of the cells die every hour. The remaining 60% of the cell survive without dividing. Let y_n be the number of cells in the petri dish after n hours. Suppose that y0=100. Determine the correct recursive formula for y_n (for all n>0) and use it to compute the value of y2

3 poi 7. The number of cells in a petri dish grows exponential with time. The function h models the number of cells present after t hours. Based on the function, which statement is NOT true? h(t) = 50(2): There were 50 cells initially in the petri dish. O The predicted number of cells doubles every 15 minutes. O Approximately 400 cells will be in the petri dish after 12 hours The predicted number of cells doubles every 4 hours.

A one-celled animal is in a petri dish and reproduces (by division) once every minute, as do its offspring. In one hour the dish is full. (a) At what time was the dish half full? (b) At what time was the dish one quarter full? (c) Do your answers to (a) and (b) depend on the size of the petri dish? Explain.

4. During a cell culture experiment, a student placed a Petri dish initially at 25°C in an incubator at 40°C. It took 4 hrs for the Petri dish to reach 37°C. After the Petri dish reached 37°C, the student took it out of the incubator and placed it in a water bath at 20°C. How long will it take for the Petri dish to reach 30°C? You can assume that for both processes, the heat transfer can be modeled by...

s method and h-0 5 TTOP Tor the value at t 2.0 obtained by Euler's method Report results to two decimal places 5. The population of a certain type of bacteria, kept in a Petri dish at a constant 25 C,changes according to the Limited Growth Model. An initial population of 10 million bacteria increases to 15 million carrying capacity, M, of this system is 40 million bacteria. (Recall: for this model the rate of population with respect to time,...

The shape of a colony of bacteria on a Petri dish is circular. Find the approximate increase in its area if its radius increases from 10 mm to 16 mm. The estimated change in area is mm2 (Type an exact answer in terms of t.) Sociologists have found that crime rates are influenced by temperature. In a town of 100,000 people, the crime rate has been approximated as C = (T-60)2 + 100, where C is the number of crimes...

A colony of bacteria is growing in a petri dish which has a maximum capacity of 60mg. The mass of bacteria is increasing at a rate given by the logistic equation. Initially there is 2mg of bacteria and the rate of increase is img per day. Write down the logistic equation satisfied by the mass, m. m' = When will the mass of bacteria be 30mg? number of days What is the mass (in GRAMS) of bacteria 10 days after...
