Answer : 4. "A , C and D "
Explanation :
Explanation: Roots are the underground structures that help in the absorption of water and minerals, provide a proper anchorage to the plant parts, store reserve food material (Carrot, Radish), and synthesize PGR (plant growth regulators). Sometimes roots get modified to perform different functions like Storage of food, respiration, climbing, etc. These types of roots are called modified roots. Examples - prop root of the Banyan tree for providing support, Pneumatophores of Rhizophora, and Mangrove plants for respiration. So, these statements are correct. A. To give support to the plant. C. To store food. D. To absorb water and minerals.

Answer : 1. "1"
Explanation :
Strong electrolytes have a degree of dissociation close to one, while weak electrolytes have a degree of dissociation less than one. Solvent nature: Solvents with a high dielectric constant show more dissociation. Dilution: As the solution is diluted, the degree of dissociation increases.
