Answer 1

Question 32 : Hypothesis - The chemical.compound (commonly found in enrisonment is toxic to humans and other living organisms living in the habitat. Experiment : ③ control group = up = injec injecting another set of lomice with salvent which was used to dissolve the chemical compound. (18) Test group = inject 10 mice with chemical Co Independent variable = Time taken for mice to die. Cafter injection) Noe Number or percentage of mice dead. indent variable = (1) Controlled variable = living conditions for mice, feed for the mice, age of mice, volume of liquid injected.
