- Provide an example of an organism within each of the four main nutritional categories of microbes and describe how each obtains its essential nutrients. Provide evidence in support of or refuting the following statement: Microbial life can exist in the complete absence of both sunlight or organic nutrients. Polymerase chain reaction (PCR) is a technology that requires high temperatures to reproduce DNA fragments. Explain why the discovery of thermophilic archaea and their associated DNA polymerases was critical to the success of this technique. Summarize how the electron transport chain functions to produce ATP in a bacterial cell versus eukaryotic cell. Explain whether or not the term chemiosmosis accurately illustrates this process.arrow_forwardIn a population of cyanobacteria (Chlorogloeopsis fritschii) in a hot spring in Iceland, some of the bacteria can produce chlorophyll f, while some C. fritschii produce only other types of chlorophylls. Chlorophyll f absorbs light outside of the visible light spectrum, namely near infrared light, allowing the bacteria to absorb light that has not been absorbed or reflected by the water or other organisms. The ability to produce chlorophyll f is heritable, and the bacteria with chlorophyll f can live in low-light environments, such as underneath other organisms, or near the bottom of the light-penetrating zone of the spring. What is the adaptation in this population of C. fritschii living in low-light environments? (Choose one.) a) the ability to produce chlorophyll f b) the ability to produce any type of chlorophyll c) the ability to tolerate the high temperatures of the hot spring d) the ability to survive and reproducearrow_forwardTo explain: The effect on nitrogen cycle if all bacteria were absent.arrow_forward

- Antibiotics enter the environment in wastewater from pharmaceutical manufacturing plants, in wastes from farms where they are used in animals, and in sewage from human populations. (Many antibiotics are excreted in their active form.) The influx of antibiotics into the environment is a concern because the presence of these compounds in the environment selects for antibiotic resistance. As pollutants, antibiotics can also have ecological effects. Describe some of the ecological roles of bacteria, and explain why disruption of these roles by antibiotic pollution would have a negative impact.arrow_forwardListen Which of the following regarding controlling microbial growth is true? a) Microbial death rate increases with an increase in temperature b) The more microbes present, the shorter amount of time it will take to kill the population E c) Gram-positive bacteria tend to be more resistant to chemicals than gram- negative bacteria d) Microbial death rate increases as pH approaches 7 (neutral) Previous Page Submit Quiz $ R Next Page 5 of 10 questions saved % H K Page 4 of 10arrow_forwardYou were tasked to aseptically collect different environmental samples from a quarry site and process them back in the laboratory for microbial cultivation and analysis.
