Following the Deepwater Horizon accident in the Gulf of Mexico in 2010, bioremediation was used to eliminate much of the oil from the contaminated water. To encourage the growth of oil-degrading microbes, "fertilizer" including iron and nitrogen was added to the water. Which of the following statements regarding the growth of these microbes is incorrect?

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.

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.

it restores trees to areas where they once grew.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
