The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Paper Chromatography:** - Paper chromatography is a technique used to separate mixtures of substances. It involves two phases: a stationary phase and a mobile phase. 2. **Identifying the Stationary Phase:** - In paper chromatography, the stationary phase is typically the paper itself, which is often treated with a substance like silica gel. This silica layer on the paper acts as the stationary phase. 3. **Identifying the Mobile Phase:** - The mobile phase in paper chromatography is usually a solvent that moves through the paper. Common solvents include water, ethanol, or organic solvents like chloroform. The choice of solvent depends on the nature of the substances being separated. 4. **Setting Up the Experiment:** - A baseline is drawn on the paper using a pencil. A small drop of the mixture to be separated is placed on this line. The paper is then placed upright in a beaker containing the solvent. 5. **Separation Process:** - As the solvent (mobile phase) travels up the paper, it carries the components of the mixture with it. Different components will travel at different rates based on their affinity for the stationary phase versus the mobile phase. 6. **Result:** - After a certain period, the components of the mixture will be separated along the paper at different heights. The position of each component can be measured to analyze the mixture. 7. **Conclusion:** - In summary, in paper chromatography, the stationary phase is the paper (with silica), and the mobile phase is the solvent (like chloroform). **Final Answer:** - The stationary phase is silica on paper, and the mobile phase is the solvent (e.g., chloroform). ---

How do high levels of estrogen and progesterone during the follicular phase and luteal phase respectively of the ovarian cycle affect the uterus?

Assertion : Chromatography in general involves a mobile (a gas, a liquid or a supercritical fluid) and a stationary phase (like Al_(2)O_(3) column). Reason : A component which is less soluble in stationary phase takes longer time to travel through it than the component which is more soluble in stationary phase.
