<span>Compare: both RNA and DNA have 3 nitrogenous bases: Adenine Cytosine and Guanine. Also b</span>oth have a phosphate groups in their nucleotides<span>
Contrast: </span>RNA is a polymer with a ribose AND a phosphate backbone. It has four different nitrogenous bases: adenine, guanine, cytosine, and uracil.
DNA<span> is a long polymer with deoxyriboses AND phosphate backbone. It also has four </span>different<span> nitrogenous bases: adenine, guanine, cytosine and thymine.

Hope this helps
When you shower with hot water, everytime you get out the shower, outside it is cold, but inside it is hot due to the hot gas particles. When you shower with cold water, it is the opposite.
Trees are a crucial part of the<span> carbon cycle</span>, a global process in which carbon dioxide constantly circulates through the atmosphere into organism and back again. Carbon is the second most valuable element to life, you know, after water. Anyway, trees take carbon from the atmosphere through <span>photosynthesis </span>in order to make energy. This carbon is then either transferred into oxygen and released into the air by <span>respiration </span>or is stored inside the trees until they decompose into the soil. Therefore, the absence of trees would result in significantly HIGHER amounts of carbon dioxide in the air and LOWER amounts of oxygen! The filthy air would also be full of airborne particles andpollutants like carbon monoxide, sulfur dioxide and nitrogen dioxide and its temperature may increase by up to 12 F.
