Answer:
Because of the several steps with high temperatures and also (heavy ) changes in temperature.
Explanation:
PCR consists of a serie of 20–40 repeated temperature changes. Those series or cycles are also called thermal cycles.
The individual steps (common to most PCR methods) are as following:
→Denature template : 99 °C for 2 minutes
→Anneal primers to template : 55 °C for 2 minutes
→Extension of the primers by heat stable DNA polymerase :72 °C for 2 minutes
As we can notice, will in a relatively short time, different temperatures be used. It's important that the used polymerase will be functional at corresponding temperatures, as well as (heavy) temperature changes.
→ Since the bacteria Thermus aquaticus lives near thermal vents in the ocean floor and grows at temperatures of up to 98°C, it's used to corresponding temperatures.
If other enzymes will be used, i.e enzymes functional in lower temperatures (several) steps will not continue or will not be executed properly. To avoid this it's important to use the best temperature resistant enzymes.
1.) Photosynthesis and cellular respiration are often described as been chemically opposite because the product of the photosynthesis process is the reactant of the cellular respiration process and vice versa.
<em>The reactants of cellular respiration are glucose and oxygen and these happen to be the products of photosynthesis also. During the process of photosynthesis, plants take in carbon dioxide and water in the presence of sunlight to produce glucose and oxygen. During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water, which are the reactants of the photosynthesis process. </em>
2.) Photosynthesis and cellular processes are related to each other, this is because, the photosynthesis process produces the glucose, which cellular respiration used to synthesis energy in the cells of living organisms. <em>Thus, the glucose producing plants depend on the living organisms that carried out cellular respiration to produce carbon dioxide and water, which is the necessary reactants for photosynthesis process. The organisms using cellular respiration also depend on plants to produce glucose and oxygen for their use.</em>
