In an experiment, the group of test subjects left untreated or unexposed to some procedure and then compared with treated subjects in order to validate the results of the test
<span>The autumnal equinox takes place on the same date in the southern hemisphere as the spring equinox, since the seasons are in "opposite" order as the calendar falls. In this case, the autumnal equinox would fall on March 21, since this is the date of the spring equinox in the northern hemisphere.</span>
Explanation:
the scientific method is the process that involves various steps to develop knowledge about the natural world that has characterized the development of science
Steps of the scientific method
•ask a question
•do background research
•construct a hypothesis
•Test your hypothesis by doing experiment
• Analyze your data and draw conclusion
•communicate your results
Answer:
The information is not complete in the question to say clearly that how long will be the PCR amplified product. Firstly, it is mentioned that the primer sequence would bind to 60 different sites in the genome. So, there will be 60 different PCR products. Each PCR product could be of different length. This is because we don't know that what is the length of each gene which is going to be amplified in all those 60 cases. Therefore, it is not possible to say what would be the length (in base pairs) of each PCR product as well as the average length. More information is needed to conclude.
