The contrasting characteristics generally in a pair used for identification of animals in Taxonomic Key are referred to as:

1. Lead

2. Couplet

3. Doublet

4. Alternate 

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

Which of the following characters, are defining features
of all living organisms?
(A) Growth from inside
(B) Sexual reproduction
(C) Metabolism
(D) Response to stimuli
(E) Cellular organisation

1. Only (C), (D) and (E)
2. Only (A) and (B)
3. Only (B), (C) and (D)
4. All except (B) 

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

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

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

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
