Answer #1

As mentioned in the question the organism is single celled that is it is unicellular moreover it has a nucleus thus it is an eukaryote as prokaryotes do not have a membrane bound nucleus.Moreover there were nuumerous hair like structure which is called cilia which is used for both locomotion and feeding.Thus the organism must be PARAMECIUM.

It must be paramecium as paramecium is single celled eukaryote that has a membrane bound nucleus and its whole body is covered by fine hair like structures referred to as cilia .Thus the features given in the question matches with feature of PARAMECIUM.

Thus by reviewing the features of the organism viewed in the microscope and features of Paramecium it was clear that organism was paramecium.Which made the microbiologist to come into conclusion that the organism which he was viewing in the microscope was Paramecium.
