Phosphorus is never found in the atmosphere?
I think the third statement is correct. RNA consist of ribose sugar while DNA consist deoxyribose sugar. and the nitrogenous base that is different would be the thymine in DNA becomes a uracil in the RNA
Thats false, plants and animals need a lot of sun and WATER to survive so a tropical climate is better
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 :

Atoms may have different numbers of neutrons. Atoms are the smallest fraction of an element that can exist, and still show the properties of the element. They consists of electrons (negatively charged), protons (positively charged), and neutrons (no charge). The number of electrons is equivalent to the number of protons normally however an atom may loose or pick up electrons and have a positive charge or negative charge. The number of neutrons in the nucleus may vary within a given element to give varieties of atoms we call isotopes.
