What are people's favorite colors? How does the color purple make people feel? Something like that

Hi!

We experiment by following scientific principles, and the scientific method. It's through this method that we reach scientific, credible answers which are factual.

In some cases, an experimental question <em>cannot </em>be answered via experimentation. This happens when the question at hand is something that cannot be explained or proved scientifically.

These questions will be <em>subjective </em>and will vary depending on the person. Such questions will ask things like 'What is everyone's favourite animal?'

For this question, we can't exactly answer it scientifically. Therefore, we will not carry out scientific experimentation onto it.

This is when we will use a <em>survey, </em>instead of an <em>experiment. </em>

Hopefully, this helps! =)

A standard PCR cycle includes three steps: denaturation (95°C), annealing (55°C), and elongation (65°C).
xz_007 [3.2K]

Answer:

Denaturation process: The DNA template  

Annealing process: Primers  

Elongation process: dNTPs and Taq polymerase

Explanation:

For the denaturing process, the only ingredient that is required is the DNA template that will be separated from a double helix (or double strand) into a single strand, by increasing the temperature to 95 C, (at this temperature the hydrogen bonds that keep together the double stranded break). After the double strand is denatured, the following process is annealing. For this, the required ingredient are the primers; these primers will hybridize or anneal according to the nucleotide complementarity to the single strand of the DNA. Finally, for the Elongation process, you will require the Taq polymerase and the dNTPs. The enzyme will synthesize or “generate” a new strand of DNA based on the DNA template, using the provided dNTPs in the direction 5’ to 3’.

I hope this clarify you inquiry.

How is movement of energy through aerobic cellular respiration
Alex_Xolod [135]

Cellular respiration is the process that cells use to break down food to use as an energy. Aerobic cellular respiration uses oxygen and yields many more ATP molecules than anaerobic cellular respiration, which does not use oxygen and yields only two ATP molecules.

What is one role of ATP in the light-independent reaction of photosynthesis?
azamat
Adenosine Triphosphate is a compound used by the cell to store energy. Together with NADP, ATP is responsible for carbon dioxide reduction. Carbon dioxide is said to be reduced when it loses oxygen, reacts with hydrogen or gains electrons. Carbon dioxide becomes part of Glycerate 3-phosphate.
