The process that results in Ms. Milly’s wilting lettuce becoming firm is osmosis. The explanation is below.
OSMOSIS:
- Osmosis is the process by which water molecules move from a region of high concentration to a region of low concentration via a semipermeable membrane.
- According to this question, Ms. Milly, occasionally sprinkles water on her wilting lettuce and notices that they became firm.
- The firmness of the lettuce is as a result of the movement of water into the leaf cells due to a process called osmosis.

Answer:
The correct choice is ''ion electrochemical gradients''.
Diffusion of ions across membranes through specific ion channels is driven by <u>ion electrochemical gradients</u>.
Explanation:
An electrochemical gradient can be considered as that electrical (electrostatic pressure) and chemical (diffusion) force that determine the movement of molecules and ions across the membrane. This electrochemical gradient, in addition to causing movement of substances through cell membranes, is also a type of potential energy available for the performance of different cellular activities, potential energy called membrane potential.
