Animals, dogs and mammals represent
1. | Taxa at different levels |
2. | Taxonomic hierarchy |
3. | Taxa at equivalent level |
4. | Categories at equivalent level |
Study of diversity of organisms and evolutionary relationship amongst them on the basis of all possible characters is called as
1. | Taxonomy | 2. | Systematics |
3. | Alpha-taxonomy | 4. | Phylogeny |
First step of taxonomy is
1. | Classification |
2. | Nomenclature |
3. | Identification |
4. | Characterisation |
Practical purpose of taxonomy or classification is to:
1. | facilitate the identification of unknown species |
2. | explain the origin of organisms |
3. | know the evolutionary history |
4. | identify medicinal plants |
The term ‘systematics’ refers to
1. | identification and study of organ systems |
2. | identification and preservation of plants and animals |
3. | diversity of kinds of organisms and their relationship |
4. | study of habitats of organisms and their classification |
Biosystematics aims at:
1. | The classification of organisms based on broad morphological characters |
2. | Delimiting various taxa of organisms and establishing their relationships |
3. | The classification of organisms based on their evolutionary history and establishing their phylogeny on the totality of various parameters from all fields of studies |
4. | Identification and arrangement of organisms on the basis of cytological characteristics |
