Select correct combination of the statements regarding
the taxonomical aids.
A. Herbaria serve as quick referral systems in
    taxonomical studies.
B. Keys are generally analytical in nature.
C. Manuals provide the index to the plant species
    found in a particular area.
D. Museums have collections of preserved animal
    specimens only, for study and reference.

1. A, B, C

2. B, D

3. A, B

4. A, C

What is incorrect statements-

1. Organisms that can respond to stimuli are with a well developed nervous system..

2. Generally growth and reproduction are mutually exclusive events in higher organism.

3. Mules and sterile worker bees do not reproduce.

4. Metabolic reactions may take place in isolated cell-free systems

Species are considered as 
1. artificial concept of human mind which cannot be defined in absolute terms
2. real units of classification devised by taxonomists
3. real basic units of classification
4. the lowest units of classification

Mark the incorrect one (with respect to taxonomic key)

1. Based on contrasting characters

2. Generally analytical in nature

3. Each statement is called couplet 

4. used for identification of plants or animals

Animals, dogs and mammals represent

1. Taxa at different levels

2. Taxonomic hierarchy

3. Taxa at equivalent level

4. Categories at equivalent level

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

First step of taxonomy is

1 Classification

2 Nomenclature

3 Identification

4 Characterisation

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

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

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
