What are the factors affecting solubility?
1. Temperature: Generally, higher temperatures increase the solubility of solids and liquids in solvents. 2. Pressure: For gases, higher pressure means higher solubility in liquids or solids. 3. Concentration: Increasing the concentration of a solute in a solution leads to higher solubility. 4. Nature of the Solvent: Polar solvents generally have high solubility for polar solutes, while non-polar solvents have higher solubility for non-polar solutes. 5. Nature of the Solute: The polarity of a solute affects its solubility. Polar solutes dissolve better in polar solvents and non-polar solutes dissolve better in non-polar solvents. 6. Intermolecular Forces: The strength of the interactions between the solute and solvent molecules affects the solubility of a solute in a particular solvent. 7. pH: The pH of a solution affects the solubility of some solutes. Acids and bases can undergo reactions that can affect the solubility of the solute in the solution. 8. Surface Area: For solids, increasing the surface area of the solids increases their solubility. This is because more molecules can come into contact with the solvent molecules.

What are the steps of phagocytosis?
1. Plasmalemmal wrapping or pseudopod formation: Phagocytic cells extend their cellular membrane around an invading particle. 2. Engulfment: The particle is enclosed within a membrane-bound vesicle inside the cell. 3. Vesicle Fusion: The endosome or vesicle containing the particle merges with a lysosome, a vesicle which contains digestive enzymes. 4. Degradation: The enzymes in the lysosome digest the particle and its contents are absorbed. 5. Waste Disposal: The cell releases waste materials, such as undigested material and cellular debris, out of the cell.
