Your team suggests changing the temperature of the oil spill site in order to enhance the bioremediation process. Do you consider this decision effective? Why and why not? Explain, in your answer, the effect of changing the zone tension on the homeostasis capacity of the bacteria you use and their ability to withstand the osmotic pressure of the new surrounding solvent. In your answer, state how osmosis works and state the degree of tension of the solution (isotonic, hypertonic or hypotonic). Explain why osmosis is really just a special case of facilitated diffusion
Some suggest that lakes without fish populations due to acid depostiion can simply be stocked with young fish.
Who might be satisfied with this solution? Explain.
Explain why this action does not solve the problem.
What is the range of salinities over which Halobacterium NRC-1 is able to survive? Why specifically does Halobacterium NRC-1 not survive at higher or lower salt concentrations?
My answer
The range in which Halobacterium NRC-1 would able to survive is between 234 ppt and 400 ppt. Halobacterium NRC-1 does not survive in lower salt concentrations because......

Defend or refute this statement: The upper-temperature limit to life is unrelated to the stability of proteins or nucleic acids. How influential is microbial activity on the geological processes of mineral formation and deposition compared to biological processes? (argue both sides of this one). What challenges and advantages do you see with the use of extremeophiles in industrial or bioremediation applications?arrow_forwardPlants absorb several ions and water from soil. For this reason, it is necessary for the soil to have a pH value at the range of 6.0 – 8.0. Again, if the p4 is less than 3.0 or greater than 10, then the beneficial microbes of the soil die. Normally rainwater is slightly acidic, its p# value is 5.5. During thunderstorm nitrogen and oxygen of air react to form nitric oxide, which is oxidized to form nitrogen-dioxide. This nitrogen-dioxide reacts with water vapor and forms nitrous acid and nitric acid. Acid-rain occurs because of it. 2NO2+ H2O → HNO2+HNO3 Examination of soil in a region of Rajshahi revealed that its p" value was 6.43. Nitrogen-dioxide is formed in the air because of thunderstorms, and its concentration is 0.297 ppm. What will be the difference between the p" value of the soil after rain and the lowest standard pH value ?arrow_forward

(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_forwardDiscuss the possibility of life on Mars.
