Answer 1

his strain + substance a his straint substance is -LE The -LE TLE (carcinogenic non carcinogenic ) his strain & substance C - LE + LE (undetermined The 1st one is carcinogene because in the presence of substance A his is produced of this, the hist revertants are produced thereby signifuging this crecimigenic potential. Per ease of B the hist reveetants were not produced in eithel of the case - hence it was found to be non carcinogenic. In case of c the mutagenecity is undetermined because the revertants were formed even in Le plates & not in Le plates. Thus, it needs to be tisted upen fusthee...
