Answer:

Are part of the Archaea AND oxidize hydrogen gas to produce methane. (Ans. E)

Explanation:

Methanogens are micro-organism which belongs to archaea, and they are obligate anaerobes which can survive without oxygen. They are producing methane as a byproduct of their metabolism.

Methanogen belongs to archaea domain which are extremophiles such as hot temperature, or highly salty environment. Methanogens can live in guts of cow, and in muck from sewage treatment plants.

Methanogens consume carbon dioxide and hydrogen and release methane gas. They are basically two types in shapes coccus (circle shape) and bacillus (rod shape).

azamat

Answer:

photochemical

hydrocarbon

Explanation:

Morning commuter traffic in cities contributes to<u> photochemical</u> smog. In this type of air pollution, a mixing of <u>hydrocarbons</u> from certain plants, nitrogen oxides from cars, and UV radiation from the sun results in a variety of pollutants, such as ground-level ozone, which can cause coughing and breathing problems.

<em>Photochemical smogs are caused by the photochemical reaction of hydrocarbon and nitrogen oxides in the lower atmosphere with sunlight playing a major role. The reaction of the hydrocarbon with the nitrogen oxide in the presence of light leads to the evolution of ozone gas while nitrogen oxide has the capacity to react with the sunlight on its own to produce nitrogen dioxide. This result in the formation of smog</em>

How does nitrogen leave a food chain?
vitfil [10]

Answer: c

Explanation: Plants and animals need nitrogen to make proteins but they cannot take it in from the air. Because nitrogen is unreactive as a gas, it has to be transformed into a new molecule. When bacteria in the soil takes nitrogen from the air, it becomes nitrates. Finally, it can move through the food chain in this form.

gizmo_the_mogwai [7]
I think the use of ibuprofen should be questioned with the concurrent  use of hydrocortisone, a 28 corticosteroid. The use of medication together increases the risk of gastrointestinal bleeding. Ibuprofen and sertraline azithromycin, or ipratropium will not cause adverse effects.
