Statement-1: Ascent of sap is an active process and it requires ATP energy. Statement-II: Transpiration pull model is the most acceptable to explain the transport of water

Statement 1: the process of diffusion does not require any input of energy. Statement 2: Diffusion involves movement of particles from a region of higher concentration to a region of lower concentation.

Statement-1 : The freezing of water is an endothermic process. Statement-2 : Heat must be removed from the water to make it freeze.

Statement l. mineral salt absortpion is an active process. II. Explanation metabolic energy is not used in active absorption

Statement-1: There is no exchange in internal energy in a cyclic process. Statement-2: In a cyclic process, the system returns to original state in a number of steps.
