The correct Answer is:
To solve the question regarding the two phases of mineral absorption (Initial or 1st phase and 2nd phase), we need to analyze the characteristics provided and match them to the appropriate phase. ### Step-by-Step Solution: 1. **Identify the Phases**: - **Initial Phase (1st Phase)**: This phase is characterized by rapid uptake of ions and is a passive process. - **Second Phase (2nd Phase)**: This phase involves active transport and is metabolic in nature, requiring ATP. 2. **Match Characteristics to Phases**: - **I. Rapid uptake of ions**: This occurs in the **Initial Phase** (1st Phase). - **II. Active process**: This is characteristic of the **Second Phase** (2nd Phase). - **III. Passive transport**: This is associated with the **Initial Phase** (1st Phase). - **IV. Occurs through ion channels**: This is also related to the **Initial Phase** (1st Phase). - **V. Slow process**: This is indicative of the **Second Phase** (2nd Phase). - **VI. Absorbed ions are free and exchangeable**: This is true for the **Initial Phase** (1st Phase). - **VII. Not exchangeable with external medium**: This applies to the **Second Phase** (2nd Phase). 3. **Summarize the Findings**: - The **Initial Phase** (1st Phase) includes: - Rapid uptake of ions (I) - Passive transport (III) - Occurs through ion channels (IV) - Absorbed ions are free and exchangeable (VI) - The **Second Phase** (2nd Phase) includes: - Active process (II) - Slow process (V) - Not exchangeable with external medium (VII) 4. **Conclusion**: - Based on the analysis, the correct option that matches the characteristics of both phases is **Option 1**.
