What are the two main differences between RNA and DNA nucleotides? What are three types of complementary base pairings in RNA? Order the pairs by the strength of the bond.

DNA contains genetic information and codes for making proteins. RNA determines which traits are created, activated or deactivated carrying out the instructions from DNA.DNA cannot leave the cell nucleus while RNA can. DNA is in the shape of a double-helix, and RNA has only one strand.

The three types of complementary base pairings would be C(cytosine) with G(guanine) and U(uracil) and A(Adenine). *RNA uses Uracil intead of Thymine* and the strongest bonds are G with C since they produce more hydrogen bonds.

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.    

it cools slower in the earth meaning the crystals have more time to form than lava on the surface
