The highest category for classifying living organisms in taxonomic hierarchy will be:
1. Kingdom
2. Domain
3. Supraclass
4. Phylum for animals and Division for plants
In the taxonomic hierarchy, for Prunus persica [peach]:
I: | Genus will be a taxon and Prunus will be a category |
II: | Species will be a taxon and persica will be a category |
1. Both I and II are correct
2. Only I is correct
3. Only II is correct
4. Both I and II are incorrect
When a plant species is reported, the author should submit a herbarium sheet of the specimen (Dried plant with reproductive part placed on a sheet of paper). This is designated as type specimen where:
I. Holotype is the type specimen submitted by the original author at the time of publication.
II. All other specimens of the same species collected at the same time are called isotypes.
1. Both I and II are correct
2. Only I is correct
3. Only II is correct
4. Both I and II are incorrect
Sometimes the terms such as biological classification, taxonomy and systematics are used as synonyms. However, if we define them separately, which of the following would be acceptable?

II: | Taxonomy is the study of principles and procedures of classification |
III: | Systematics is the study of organisms and their diversities and the evolutionary relationships among them |
1. | Only I and II | 2. | Only I and III |
3. | Only II and III | 4. | I, II and III |
