A monophyletic group, a group of organisms that consists of a common ancestor and all its lineal descendants, is called as:
1. Taxon
2. Class
3. Clade
4. Division
Which taxon in plant taxonomy is equivalent to the ‘phylum’ in animal taxonomy?
1. Supraclass
2. Clade
3. Domain
4. Division
Which taxonomic category is not correctly matched with name regarding the classification of the housefly?
1. | Phylum: Arthropoda | 2. | Class: Diptera |
3. | Family: Muscidae | 4. | Genus: Musca |
Of the known and described number of species, Arthropods are maximum in number. Which of the following groups will be next in number?
1. Molluscs
2. Fungi
3. Vascular plants
4. Algae
"Canis sp." means:
1. an unspecified species of the genus Canis
2. two or more species of the genus Canis
3. an unspecified sub-species of the genus Canis
4. two or more sub-species of the genus Canis
Which of the following cannot be the defining properties of living organisms?
I. Growth
II. Reproduction
III. Emergent properties
IV. Cellular organization with metabolism
1. I, II and III
2. I, III and IV
3. II, III and IV
4. I, II, III and IV
All the following can be the arguments in favor of many scientists not believing viruses to be living organisms except:
1. Not having a cellular organization
2. Lack of metabolic machinery of own
3. Presence of RNA as a genetic material in many cases
4. They can be crystallized
In the polynomial system of nomenclature:
1. A generic name was combined with a specific name that was from one to several words long
2. A generic name one to several words long was combined with a specific name
3. A generic name one to several words long was combined with a specific name that was from one to several words long
4. All words used were initiated with a capitalized letter
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?
I: | Classification is the ordering of organisms into groups |
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 |
