Genus represents aggregate of closely related species. Which of the following group of species does not belong to same genus?

1 Potato, Brinjal

2 Brinjal, makoi

3 Lion, Leopard

4 Potato, Sweet potato

 

What is incorrect for taxonomic hierarchy?

1 There are 7 obligate and more than 21 intermediate categories

2 Higher the category, fewer the number of organism

3 Lower the category, more the number of common features

4 Greatest similarity in structure is found in between members of a species

Select incorrect statements with respect to living beings

1 Growth cannot be taken as a defining property of living organisms

2 Growth can be easily observed in vitro culture

3 Metabolic reactions cannot be demonstrated outside the body in cell-free system

4 All organisms, from the prokaryotes to the most complex eukaryotes can sense and respond to environmental cues

Choose the wrong statements with respect to distinguishing characteristics of living beings

1 In majority of higher, the growth and reproduction are mutually exclusive events

2 Degrowth will occur when catabolism exceeds anabolism

3 Isolated metabolic relations in-vitro are neither living things nor living reactions

4 Growth cannot be taken as a defining property of living organisms if we take increase in body mass as a criterion on growth

Which statements is incorrect with respect to genus?

1 Each genus may have one or more than one specific epithets

2 It comprises a group of related species

3 It has more characters in common in comparison to species of other genera

4 Potato and brinjal belong to different genus

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

Mark the correct statements with respect to living organisms 

1 Growth and cellular organisation are considered as defining properties of living organisms

2 Reproduction can be all inclusive defining characteristic of living organisms

3 Living organisms are self replicating, self regulating and evolving interesting systems

4 isolated metabolic reactions in vitro are living things

Biologists have established certain procedures and techniques to store and preserve the information as well as specimens. Amongst these which one has collection of both preserved plant and animal specimens?

 1 Zoological parks

2 Herbarium

3 Museum

4 Botanical gardens

First step of taxonomy is

1 Classification

2 Nomenclature

3 Identification

4 Characterisation

Living organisms exhibit distinctive characteristics to differentiate from non-living objects. Which one of the following statements can be considered as defining property of living things?

1 Increase in body mass as a criterion for growth

2 Reproduction is synonymous with growth in unicellular organisms

3 Ability of living organisms to sense their surroundings

4 Metabolic sections that can be demonstrated outside the body in cell-free system only
