(iii) Nerve cells
(iv) Prokaryotic
(v) Unicellular

• A. i and ii
• B. i, ii and iv
• C. ii and iv

Answer 1

The correct option is D iv and v

Monerans include bacteria, archaea, actinomycetes, and cyanobacteria. Some of them have cell walls, but these are made of peptidoglycan. Some monerans are heterotrophic, but others are autotrophic. Nerve cells are a characteristic of animals. The kingdom Monera is the only kingdom made of prokaryotes. Although some monerans form colonies, all of them are basically unicellular.
