Your roommate left the deviled eggs out on the counter for 8 hours, but is happily eating them for breakfast. "We learned that bacteria take 20 minutes to reproduce at room temperature," he explains, "so I figure at mos there's only a couple hundred in there. No big deal." What is your response, after remembering the equation N Noert, and the fact that e is roughly equal to 2.72? %3D O The intrinsic rate of increase (r) is only equal to 2, since each bacterium divides in half. No big deal. Hand me a fork! O If just 1 dangerous bacterium landed on your egg at the beginning of the night, there would now be approximately 1.7 million. They have been growing exponentially all night! You might be okay, but better not risk it. O If just 1 dangerous bacterium landed on your egg at the beginning of the night, there would now be nearly 27 billion. They have been growing exponentially all night! Call me if you need a ride to the hospital later. So the population only doubled 3 times for every hour, which is 24 times over the night? That makes only about 72 bacteria. If you waited until tomorrow, you might get poisoned. For now, though, bon appetit!

In a certain culture of bacteria, the rate of increase is proportional to the number present. (a) if it is found that the number doubles in 6 hours, how many may be expected at the end of 18 hours? (b) If there are 10^2 at the end of 4 hours and 8(10^2) at the end of 8 hours, how many were at the beginning?
Bacteria grow in a nutrient solution at a rate proportional to the amount present. Initially, there are 250strands of the bacteria in the solution which grows to 800 strands after seven hours. Show (a) anexpression for the approximate number of strands in the culture at any time t and (b) the time needed forthe bacteria to grow to 1600 strands.

Before development of a vaccine against this microbe, thedisease it caused accounted for two-thirds of bacterial meningi-tis cases during the first year of life but is still the number oneleading cause of mental retardation in patients who survive seri-ous disease due to permanent central nervous system disorders.What is the microorganism?(a) Haemophilus influenzae type B(b) Haemophilus influenzae type A(c) Neisseria meningitidis(d) Streptococcus pneumoniae(e) Listeria monocytogenes
If the volume of a Staphylococcus aureus cell is estimated at 0.5 μm3, how many cells could be accommodated, in principle, in 5 mL of saturated culture? (1 mL = 1 cm3). Show your calculations.
In light of the COVID-19 pandemic many people are more conscious about cleaning their household surfaces. Your sister says she is going to disinfect the kitchen counter. She sprays on the Lysol antibacterial kitchen cleaneser and immediately wipes off the surface. Is she disinfecting the surface? Explain why or why not?
The body uses water as a coolant. However, polychloride biphenyls (i.e., PCBs) are an even more efficient, lipid-soluble coolant. One of the advantages is that PCBs remain fluid over a wide range of temperatures, even above 40o Celsius (or 104o Fahrenheit). They are not a by-product of any part of human metabolism. Why doesn’t the human body use PCBs as coolants?
50. During an experiment, equal aliquots of Escherichia coli and Staphylococcus aureus are separately sonicated at the same level to mechanically disrupt bacterial cells. E. coli cells are disrupted, but there is minimal disruption of S. aureus cells. Which of the following bacterial structures best explains this difference? OA) Cytoplasmic membrane OB) Outer membrane OC) Peptidoglycan layer OD) Phospholipid bilayer OE) Polysaccharide capsule

All questions a) Name structures P, Q and R. b) Name substance S . c) What is the enzyme encoded by gene I. Give its function. d) What will happen if substance S is absent in the medium?
You measure your E. coli and find them to have an OD600 of 1.20. You have 50 ml of culture, and you know that there are 2.5x109 cells per 1.0 OD600. Based on this information, how many E. coli cells are present in the culture you’re about to centrifuge?
A bacterium has a generation time of 30 minutes. You transfer cells from an exponentially growing culture to a fresh source of the same medium so that the freshly inoculated medium contains 3.2 x 106 cells per milliliter. This new culture does not exhibit a lag phase. About how many cells (per milliliter) should you have after 1.5 hours incubation?? Solve this step by step and by using formula
