<u>Explanation:</u>
1. It was as a result of a blurry picture of the DNA eye made by scientist,
Maurice Wilkins, this glimpse of the DNA made James Watson even more curious about the DNA.
2. They were considered an unlikely pair due to their age difference of about 12 years. Seemed unlikely because there was a 12 year age difference. However, they are considered a perfect team to solve the structure since James Watson has a strong background in biology, while Francis Crick is an expert in x-ray crystallography.
3. Other researchers also racing to find the structure include;
- Rosalind Franklin, and
- Linus Pauling.
4. It is important to note that the data provided by Rosalind Franklin enabled Watson and Crick to better understand the chains that make up the DNA.
5. In the year, 1962 they were awarded the Nobel prize in Physiology and Medicine. They were only three recipients because at the time they were the only living early contributors to the study of the DNA.

Answer:
The correct answer is - brand of floor wax.
Explanation:
The independent variable is the variable or the factor in an investigation which is manipulated or change in the experiment and affects the dependent variable and produces a various result.
In this investigation, there are different brands of the floor was are the independent variable as they are changed to see the effect on the scratches on the floor on 20 tiles for each brand.
