SDS page is use to analyze protein molecules.

Explanation:

SDS -PAGE(sodium dodecyl sulfate) is a discontinuous electrophoretic system that was developed by Ulrich Laemmli which is use to analyze and separate proteins that have molecular mass between 5 and 250KDA. Each SDS PAGE contribute two negative charges that overshadow the protein positive charges.

plants absorb water from the soil by osmosis. root hair cells are adapted for this by having a large surface area to speed up osmosis. the absorbed water is transported through the roots to the rest of the plant where it is used for different purposes: it transports dissolved minerals around the plant.
