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
In single-celled organisms, growth and reproduction are often used interchangeably, and the increase in the number of cells is a direct result of reproduction.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:

| 2. | The first word in a biological name represents the genus while the second component denotes the specific epithet. |
| 3. | Both the words in a biological name, when handwritten, are separately underlined, or printed in italics to indicate their vernacular origin. |

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
