Name three reasons fossil fuels are detrimental to earth

2 answers:

5 0

1. In order to procure fossil fuels, or even to burn them, we create a great deal of pollution. All of the pollution that is being created is extremely bad for the Earth because it contributed to global warming.

2. When we create new mining cites, we remove trees and soil that was once the home to plant, animal, and insect life.

3. Oil is a very useful fossil fuel, it is used to power many things. But due to the very dangerous nature of fossil fuels, an explosion in Mexico in 2010 caused 210,000,000 U.S. gallons of oil to spill into a gulf. This spill lead to the drowning and poisoning of immeasurable amounts of aquatic animal life.

If adenine didn’t always pair with thymine and guanine didn’t always pair with cytosine, the new DNA ladders wouldn’t always be

zloy xaker [14]

Answer:

they wouldnt be identical because for example Guanine could be paired with thymine in the original DNA strand but could decide to pair with adenine in the replication DNA. that would make a different type of DNA.

Explanation:

DNA replication is a beautiful process. In DNA replication adenine only pairs with thymine and guanine only pairs with cytosine. this ensures that a replication of the DNA will be the same type of DNA.

Replication works like this. Helicase splits open the DNA and each side is copied by DNA polymerase. If let's say the nucleotide bases for side 1 are ATGCGA then the DNA polymerase will pair these with the matching bases TACGCT which will make the same DNA but if each base could pair with any base they want that could create a few different variations of the original DNA. ATGCGA could very well be paired with TCGACA or CGACTA which would created two different types of DNA.
