the scientist is studying the effect of water purification tablets on the creek water in her local area. She collected several different 2 L samples from a creek. For each sample, she measured the number of coliform group bacteria colonies in the water initially, and then added a water purification tablet and measured the number of coliform group bacteria colonies over time. She found that the following equation was a good fit to the data:
C(t) = 80e−0.05t + 8(t + 1)−0.5.Her model says that C(t) is the number of coliform group bacteria colonies at time t, where t is
measured in minutes since the tablet was added to the water.
(a) According to this model, how many coliform group bacteria colonies would initially be in a 2 L sample of the water?
background information:
The quality of drinking water is determined by tests for coliform group bacteria, which are organisms found in soil and in the intestinal tract of warm-blooded animals. Coliform group bacteria are not considered to…
Some marine bacteria, such as Cytophaga species, live and grow well inside fish guts and in waters below freezing temperatures. These bacteria are:
a) Halophilic
b) Psychrophilic
c) Friophilic
d) Thermophilic
e) Mesophilic
