1. Which one of the following is not a characteristic of living organisms?

A. Growth
B. Reproduction
C. Metabolism
D. Photosynthesis

Answer: D. Photosynthesis
Explanation:
Photosynthesis is a process carried out by specific organisms (e.g., green plants, algae). Not all living organisms photosynthesize (e.g., animals, fungi). On the other hand, growth, metabolism, and reproduction are universal or near-universal features of living beings.

2. Binomial nomenclature was first proposed by:

3. The correct sequence of taxonomic hierarchy is:

A. Kingdom → Phylum → Class → Order → Family → Genus → Species
B. Kingdom → Class → Phylum → Order → Family → Genus → Species
C. Phylum → Kingdom → Order → Class → Genus → Family → Species
D. Species → Genus → Family → Order → Class → Phylum → Kingdom

Answer: A. Kingdom → Phylum → Class → Order → Family → Genus → Species
Explanation:
This is the correct hierarchical order from broadest to most specific. Kingdom is the highest category, and Species is the most specific.
