1. Who, amongst the following, has been called as ‘The Darwin of the 20th Century’?
1. Ernst Haeckel
2. Ernst Hemingway
3. Ernst Mayr
4. Ernst Chain

2. Consider the given two statements:

Assertion (A):	Before assigning a biological name to a living organism, it is essential to identify the organism correctly.
Reason (R):	Nomenclature or naming is only possible when the organism is described correctly and we know to what organism the name is attached to.

  

1.	Both (A) and (R) are True but (R) does not correctly explain (A).
2.	(A) is True but (R) is False.
3.	Both (A) and (R) are True and (R) correctly explains (A).
4.	(A) is False but (R) is True.

3. The correct biological name for mango should correctly be printed as:

1.	Mangifera Indica Linn	2.	Mangifera indica Linn
3.	mangifera Indica Linn	4.	mangifera indica Linn

4. The Order [taxon] of Musca domestica is:

1.	Hymenoptera	2.	Diptera
3.	Coleoptera	4.	Orthoptera

5. In the given figure showing taxonomic hierarchy for living organisms:      

I:	A would be Solanum for potato.
II:	B would be Muscidae for housefly.
III:	C would be Primata for humans.
IV:	D would be phylum for animals and division for plants.

1. Only I, II and III are incorrect
2. Only I, III and IV are incorrect
3. Only II, III and IV are incorrect
4. I, II, III and IV are incorrect

6. Consider the given two statements:

Assertion (A):	Higher the taxonomic category, greater is the difficulty of determining the relationship to other taxa at the same level.
Reason (R):	The higher taxonomic categories are more exclusive and the lower taxonomic categories are more inclusive in nature.

 

1.	Both (A) and (R) are True but (R) does not correctly explain (A)
2.	(A) is True but (R) is False
3.	Both (A) and (R) are True and (R) correctly explains (A)
4.	(A) is False but (R) is True

7. Consider the given two statements:

Statement I:	Properties of tissues are present in the constituent cells and similarly properties of cellular organelles are present in the molecular constituents of the organelle.
Statement II:	All living organisms – present, past and future, are linked to one another by the sharing of the common genetic material, but to varying degrees.

  
1. Statement I is correct; Statement II is incorrect
2. Statement I is correct; Statement II is correct
3. Statement I is incorrect; Statement II is incorrect   
4. Statement I is incorrect; Statement II is correct

8.

	Column-I		Column-II
A.	Family	(i)	Diptera
B.	Order	(ii)	Arthropoda
C.	Class	(iii)	Muscidae
D.	Phylum	(iv)	Insecta

9. Called ‘The Darwin of the 20th century’, identify the biologist who almost single-handedly made the origin of species diversity the central question of evolutionary biology that it is today:

1.	Ernst Mayr	2.	Louis Pasteur
3.	Charles Darwin	4.	Hugo de Vries

10. Consider the given two statements:

Statement I:	Taxonomists have been able to identify a vast majority of species present on Earth.
Statement II:	The number of species that are known and described range between 1.7-1.8 million.

1. Statement I is correct; Statement II is correct
2. Statement I is correct; Statement II is incorrect
3. Statement I is incorrect; Statement II is correct
4. Statement I is incorrect; Statement II is incorrect
