Answer:
Denaturation, Annealing and Extension are the steps of PCR.
Explanation:
There are three steps of PCR process.
1) Denaturation
2) Annealing
3) Extension
In the first step, the DNA denatures when they are allow to heat. In Annealing, the process of polymerization occurs. Polymerase chain reaction (PCR) is a method which is used to formed or produce billions of copies of a particular DNA sample. In this process, monomers attached to one another to form polymers and the process is known as polymerization. In the extension, new strands of DNA are formed by using the old DNA strands as a template.
Pretty sure answer is the last one... soil, habitats, water and air quality...sorry if im wrong
cells are basic building block of living things.

Well, it takes 3 moles of oxygen to completely burn 2 moles of methyl...
<span>So for every 2 moles of methyl, you need 1.5 times as much oxygen (3 divided by 2) </span>
<span>That makes your ratio 1 : 1.5 </span>
<span>You need 1.33 moles of methyl so you multiply both sides of the ratio by 1.33 = 1.33 : 1.995 </span>
<span> 1.995 moles of oxygen are needed</span>
