Consider the given two statements:
I: | Higher the taxonomic category, greater is the difficulty of determining the relationship to other taxa at the same level. |
II: | All living organisms are linked to one another by sharing of the common genetic material, but to varying degrees. |
1. Both I and II are correct and II explains I
2. Both I and II are correct but II does not explain I
3. I is correct but II is incorrect
4. I is incorrect but II is correct
Consider the given two statements:
I. | Living state and metabolism are synonymous. |

2. | Both Statement I and Statement II are incorrect |
3. | Statement I is correct but Statement II is incorrect |
4. | Statement I is incorrect but Statement II is correct |
Statement I: | Taxa can indicate categories at very different levels. |
