Burning of fossil fuels that release sulphur and nitrogen compounds into the air is identified as the major cause of acid rain in the united states.
<h3>What are the causes of acid rain?</h3>
- Acid Rain is created when sulphate and nitrogen oxides from the atmosphere react with rainwater and fall as a result.
- Sulphur and nitrogen particles that mix with the wet elements of rain are the main causes in the production of acid rain.
- Due to air pollutants, notably the excessive levels of sulphur and nitrogen released by machinery and industrial operations, acid rain is made up of water droplets that are extremely acidic.
- The emissions that are released from industries are man-made causes.
- The natural causes, such as lightning strikes in the atmosphere that release nitrogen oxides and volcanic eruptions that release sulphur oxide.
The complete question is :
What have the scientific studies identified as the major cause of acid rain in the United States?

Answer:
Phosphorylation within the nuclear export signal interferes with the function of the signal.
Explanation:
In biochemistry, phosphorylation is the addition of a phosphate group (PO4) to a protein or other molecule. Phosphorylation is a major player in protein regulation mechanisms, preventing protein-catalyzed reaction product from accumulating in the body causing problems.
However, in some cases phosphorylation may cause nuclear accumulation of a protein in the nucleus of the cell. An example of this is the protein shown in the question above. In this case, phosphorylation in the nuclear export signal interferes with the signal function, resulting in protein accumulation in the nucleus.
