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. |

| III | Order: | - ales |
| IV | Family: | - idae |
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 |
