Part 1. De-chlorinated water is water that doesn't contain any chlorine.

Part 2. Tap water contains chlorine, the chlorine should be removed from the water before putting in an aquarium. This is because Chlorine is known for cleaning and killing micro-organisms. It should not be put into an aquarium because it can be harmful to the life inside of it.

Part 3. There are various ways to de-chlorinate water. One of the ways is by dissolving a tablet of potassium <span>metabisulfite into it. 1 tablet = 20 gallons of water dechlorinated.

1.
<em>De-chlorinated water </em>is simply a sample of water without any chlorine components.
2.
Water is typically chlorinated to sanitize water from <u>all</u> micro-organisms. This is good because it keeps harmful bacteria and other risky organisms away from water. However, this is bad because it kills <u>all</u> organisms. This is why planted aquariums <u>never</u> apply a chlorinated solution. It must be dechlorinated if you want the living organism to live in the aquarium. 
3.
There are many complex and simple methods to de-chlorinate water. I will briefly list them: Boiling, adding a dechlorination agent to water, an air pump, and an Aerating Sprayer. Boiling water is the simplest way, but chloramine and chlorine will not be <em>completely</em> gone. Usually, adding a dechlorinating agent is one of the best. You can add <em>vitamin C tablets</em> to water. <em>Vitamin C</em> tablets are VERY commonly used to dechlorinate water with a huge concentration gradient (pools, hot tubs, etc).

What is the building block of DNA?
Bogdan [553]
Deoxyribonucleoside Triphosphate, which is the more specific form of Deoxyribonucletides.

When DNA is synthesised by DNA polymerase by complimentary base pairing, 2 phosphate groups from Deoxyribonucleoside Triphosphate breaks away, releasing energy from the binding of the Deoxyribonucleotide to the adjacent Deoxyribonucleotide molecule via phosphodiester bond. These molecules will be called Deoxyribonucleoside Monophosphates.

Thus, the general name of the building block of DNA is Deoxyribonucleotide, and the more specific names depend on at which stage of DNA replication you are referring to.

Hope this helps! :)
