What have the scientific studies identified as the major cause of acid rain in the united states?.

Vadim26 [7]

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?

a )chemicals still in the atmosphere from the asteroid collision with the earth

b) excess solar radiation due to the depletion of the ozone layer

c) volcanic ash in the air

d) burning of fossil fuels that release sulphur and nitrogen compounds into the air

What was known before Franklin and Wilkins conducted their studies of DNA? Check all that apply. DNA is found in the nucleus of

kvasek [131]

Answer:

The correct answer will be-

1. DNA is found in the nucleus of a cell

2. Organisms store and transmit genetic information

3. Cells contain protein molecules.

Explanation:

The study of DNA started much before the discoveries of Rosalind Franklin and Maurice Wilkins.

Nucleus of cell was discovered by Robert Brown in 1831 but the material present inside the nucleus called "nuclein" (DNA) came from the studies of Johann Friedrich Miescher in 1869.

Proteins as a constituent of cell were discovered by the experimental analysis of Gerhardus Johannes Mulder in 1837.

DNA as a genetic material came from the experimental studies of Frederick Griffith in 1928, Oswald Avery, Maclyn McCarty, and Colin MacLeod in 1944, and Hershey and Chase in 1952.

Franklin and Maurice Wilkins are known for their work on the the structure of DNA as they were able to produce high-resolution X-ray photographs of DNA fibres called Photo 51 in 1952 using X-ray diffraction technique. By 1953 Franklin concluded concluded that DNA shows helical structure with phosphates on outer side.

Thus, 1. DNA is found in the nucleus of a cell

2. Organisms store and transmit genetic information

3. Cells contain protein molecules.

are the correct options.
