The question is incomplete as it does not have the options which are:
A)The concentration of sulfate in the Gulf of Mexico is sufficient for the growth of oil-degrading microbes.
B)Large amounts of iron were needed, as iron is a macronutrient for oil-degrading microbes.
C)Nitrogen gas (N2) present in air is not in a form that can be used by oil-degrading microbes.
D)The oil-degrading microbes used oil (hydrocarbons) as their carbon source.
Answer:
Large amounts of iron were needed, as iron is a macronutrient for oil-degrading microbes.
Explanation:
Bioremediation refers to a process which is performed to detoxify the natural terrestrial or aquatic habitat full of contaminated particles using the biological source like the plants, animals or microorganisms.
In the given question, the accident in the Gulf of Mexico in 2010 contaminated the aquatic body with oil so the bio-remediation technique was used to detoxify the water.
The oil-consuming bacteria were used to as bioremediation which could use the oil as a source of carbon.
The bacteria uses the support of the oxygen in anaerobic respiration and the fertilisers were added to the water to provide a source of nitrogen and iron.
The iron is used by the bacteria in its growth but it is not considered a macronutrient for the bacteria and thus is considered false.
Thus, the selected option is correct.
Answer:
Temperature increases as you gain altitude in the stratosphere and the thermosphere. Temperature decreases as you gain altitude in the troposphere and mesosphere. hope this is what you were looking for
This can lead to many answers, but typically I'd think it's D
Answer:
Higher food production per unit of agricultural land
Explanation:
With respect to the rate of fertilizer usage in relation to food production over the past 40 years, we can assume that we are almost getting to the limit to which Nitrogen fertilizer input can further increase food production using the same area of land. Further higher input of nitrogen fertilizer might be counter productive, and neither do lower use of Nitrogen fertilizer per unit area solve the predicted increase in demand of food in the future. The most plausible statement that represents future agricultural changes for maintaining an adequate food supply in response to growing population is “Higher food production per unit of agricultural land”. This can be achieved through other technological innovations compared to nitrogen use.
Answer:
Actin filaments return to their original positions (does not occur in muscle contraction, according to the sliding filament model).
