Textbook Question
Chapter 1, Problem 4CTQ
It is likely that others beside Anton van Leeuwenhoek were using lenses to look at microorganisms. After all, Robert Hooke had developed and used the compound microscope in about 1665, and the first letter from van Leeuwenhoek to the Royal Society of London was written in 1673. Why is it that we know about the observations of van Leeuwenhoek and not others? What reasons can you give for why it is important for scientists to publish the results of their research?

What is an original research? Do you think the following are ideas that may be considered as original? Support your answer with logical reasons in each case :
a. Investigation of size of bacterial cells
b. Evaluation of impact of CO2 on the environment
c. Diversity of microorganisms in the fields of Kohat University
d. Investigation of new compounds in a bacterial culture
e. Application of a strain of bacteria you isolated from the soil as PGPR
A patient comes into a hospital and has what appears to be an infection. Your microscope is broken so staining is not an option. Design an experiment to determine if the infection is caused by gram positive or gram negative bacteria.
Choose the false statement: (Regarding Pasteur’s famous experiment) The swan necked flasks were important because they allowed the broth to remain sterile, while still remaining open to the atmosphere. Pasteur’s work with the swan neck flasks was only of importance to the food industry; his work occurred long before anyone, including Pasteur, had any awareness that diseases could be caused by microscopic agents. The swan necked flasks were used to prove that life could only arise from pre-existing cells.
