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.
Answer:
The results of the heat wave are the rising of sea levels, the oceans became more acidic, and species disappeared
Explanation:
About 56 million years ago, heat wave occurs due to the increase in the concentration of greenhouse gases which are present in the atmosphere. We know that greenhouse gases such as carbon-dioxide etc were the main cause of global warming. Due to this warming, many temperature sensitive species die, melting of ice occurs which increases the sea level and carbon-dioxide deposition occurs in the ocean water which make the water more acidic and the life of marine animals will be adversely affected.
Excuse me? What does that mean?
It should be the respiratory system. The respiratory system controls the amount and exchange rate of oxygen and CO2 in your body by breathing.
