(a) Problem              (b) Hypothesis          (c) Deduction           (d) Result

3. At which point is biologist most likely to use reasoning?

(a) while taking observations                  (b) during hypothesis formulation

(c) during data organization                     (d) none of above

(a) six          (b) seven         (c) two           (d) eight

7. Who suggested that mosquitoes are involved in the transmission of malaria?

(a) Laveran        (b) Ronald Ross          (c) A.F.A king              (d) None of these
