Q1Written answer

How can one become a scientist, an economist, a historian…? Does it simply involve reading many books on the subject? Does it involve observing, thinking and doing experiments?

Show solutionHide solution
Worked solution

Reading books on any subject is just an aspect of learning. A learner must work on developing his/her observation skill and thinking power. To become a genius in a particular field, one must have a curious mind and the desire to explore new things by conducting real-life experiments and working on related projects. One must work hard and not feel taken down by mere failures. An urge to learn and discover a new theory requires a person to put in a lot of sweat and effort in any particular area of interest.

Q2Written answer

You must have read about cells and DNA in your science books. Discuss Richard Ebright’s work in light of what you have studied. If you get an opportunity to work like Richard Ebright on projects and experiments, which field would you like to work on and why?

Worked solution

Richard Ebright’s works were related to Biochemistry and Molecular Biology. His theory on the life of cells has helped the scientific community to study the cell structure, its growth and functions of different organisms. Indirectly, it also helps in detecting disease-causing organisms and discovering how these grow inside the body of living beings. Ebright’s findings about insect hormones and the photos gave him the answer to one of biology’s puzzles – how the cell could ‘read’ the blueprint of its DNA. DNA is the substance in the nucleus of a cell that controls heredity and passes genetic information from one generation to another. It determines the form and function of the cell.

If I get an opportunity to work like Richard Ebright on projects and experiments, I would like to study various life-threatening diseases. By studying the DNA, I may find useful remedies to cure chronic or fatal illnesses.
