(2) Sibling
(3) Subspecies
(4) Allopatric

Which of the following is less general in characters as compared to genus
(1) Species
(2) Family

Consider the following two statements:
I. In the single-celled organisms, we are not very clear about the usage of the two terms – growth and reproduction.
II. When it comes to unicellular organisms like bacteria, unicellular algae or amoeba, reproduction is synonymous with growth, i.e., increase in number of cells.
1. Both I and II are true and II explains I
2. Both I and II are true but II does not explain I
3. I is true but II is false
4. Both I and II are false

Consider the following two statements:
I. Cellular organization of the body is the defining feature of life forms.
II. Metabolic reactions cannot be demonstrated outside the body in cell-free systems.
1. Both I and II are true and II explains I
2. Both I and II are true but II does not explain I
3. I is true but II is false
4. Both I and II are false

Identify the incorrect statement:

What is meant by the "species problem"?
(1) The exact definition of species is still controversial.
(2) The exact mechanisms of speciation is not known.
(3) The number of species present is much more than identified species.
(4) The extinction of species is taking place at an alarming rate.

Which of the following taxonomic categories are correctly matched to their standard termination of names with respect to biological classification of plants?

1. I, II, IV
2. I, II, III
3. II, III, IV
4. I, II, III, IV

Consider the following statements:
I. Higher the taxa, more are the characteristics that members whithin the taxon share.
II. Lower the category, greater is the difficulty of determining the relationship to other taxa at the same level.
Of the two statements:
(1) I is true but II is false
(2) I is false but II is true
(3) Both I and II are true
(4) Both I and II are false

Nicotiana sylvestris flowers only during long days and N.tabacum flowers only during short days. If raised in the laboratory under different photoperiods, they can be induced to flower at the same time and can be cross-fertilized to produce self-fertile offspring. What is the best reason for considering N.sylvestris and N.tabacum to be separation species?
(1) They cannot interbreed in nature
(2) They are reproductively distinct
(3) They are physiologically distinct
(4) They are morphologically distinct
