(b) state two features each which viruses have in common with: (i) living things
(ii) non-living things

Explanation
Classification of Living things: Is the sorting/ grouping/arranging of living things (in groups); according to their common/similar characteristics/features/shared qualities.
(ii) The scientist who developed the Binomial system of classification: Carl/Carolus Linnaeus/Linnaeous
(iii) Reasons for classification of living things
- To put every lying organism into a systematic order/ specific group
- for easy identification of similar living things
- to indicate/Show the relationships between different categories of living organisms
- to show evolutionary trends in different groups of living organisms
- to trace geographical distribution of living organisms
- for easy reference
- for easy research/study.
(iv) Classification of ranks in order of hierarchy
Kingdom
Phylum/Division
Cass Order
Family
Genus
Species.
