- How well do you think bioremediation achieves the goal of cleaning up pollution?Support you answer with evidence about the success of genetic technology in manipulating bacterial characteristics, and historical facts about.Bacteria grown in a lab experience what is called an 'exponential phase' of population growth. Suppose that, during this phase, a colony of Escherichia coli you are growing has a per capita growth rate, r, of 0.0347 per minute. If the size of your colony at the start of the exponential phase is 0.25 billion cells, then approximately how large will it be in 120 minutes?What is the first known account of bioterrorism? European settlers giving Native Americans smallpox contaminated blankets People knowingly putting Salmonellainto food Tartar army catapulting plague infected bodies over a wall to infect Kaffa Dropping plague-carrying flea bombs on Japan in the 1940s
- Fill in the Blank. Round it to the nearest whole number. A mutation occurs in a single bacterium that causes it to produce a new enzyme. This enzyme helps the bacterium process nutrients more efficiently, increasing the bacterium's odds of survival. Every 30 minutes, the bacteria in the colony divide, passing their genes on to their offspring. Some bacteria survive, while others do not. Because resources are limited, the colony has a steady population of 114 bacteria. The bacterial colony is shown below at three different time intervals. The picture would be here: Assume that the survival trend shown in the diagram continues. At 3.0 hours, the mutant bacteria will make up _____ percent of the entire colony.You sample cole slaw for bacteria soon after purchase, and after it has been left out on the kitchen counter for 6 hours (room temperature), and after 12 hours (at room temperature). From the data below, CALCULATE the generation time of the bacteria in this sample (at room temperature) – that is, the time it takes for the bacterial population to double in number. Soon after purchase: 4.0 x 103 bacteria per mlAt 6 hours at Room Temperature: 1.9 x 105 bacteria per ml ( = 192 x 103 bacteria per ml)At 12 hours at Room Temperature: 1.2 x 107 bacteria per ml ( = 12,300 x 103 bacteria per ml) What do you calculate the generation time to be? (generation time is the time needed for the population to double in size ) Hint: What is double the initial population? Hint:…Industrial microbiology uses organisms to produce valuable products. In order to microorganisms to be selected for this use, which trait should they have? Give any three and list them according to decreasing significance. Explain your top answer.

- Use the table to answer the question. In 1928, Frederick Griffith injected four groups of mice with different strains of the bacteria, Streptococcus pneumoniae. The smooth strain had a polysaccharide capsule that protected the bacteria from the mouse’s immune system. The rough strain did not have this capsule. The details of each group and the results of the experiment are shown in the table below. Bacteria After injection with bacteria Group 1 smooth strain mice died Group 2 rough strain mice survived Group 3 heat-killed smooth strain mice survived Group 4 rough strain mixed with heat-killed smooth strain mice died Which conclusion about Group 4 is MOST strongly supported by the results of the experiment? A. A virus carried DNA from the smooth strain to the rough strain. B. The rough strain took in DNA from the heat-killed smooth strain. C.
