Solar- technologies convert sunlight into electrical energy either through photovoltaic panels or through mirrors that concentrate solar radiation.

Hydro- a hydraulic turbine converts the energy of flowing water into mechanical energy. A hydroelectric generator converts this mechanical energy into electricity

Tidal- energy is a form of hydropower that works by harnessing the kinetic energy created from the rise and fall of ocean tides and currents, also called tidal flows, and turns into unusable electricity

Wind- turns the propeller like blades of a turbine around a rotor, which spins a generator, which creates electricity

OTEC- plants pump large quantities of deep cold seawater and surface seawater to run a power cycle and produce electricity

Biomass- is burned in a boiler to produce high-pressure steam. This steam flows over a series of turbine blades, causing them to rotate. The rotation of the turbine drives a generator, producing electricity

Geothermal- power plants use steam to produce electricity. The steam comes from reservoirs of hot water found a few miles or more below the earth’s surface. The steam rotates a turbine that activates a generator, which produces electricity

A selectively permeable membrane sac filled with water and large molecules of starch is suspended in a beaker of distilled water
madreJ [45]

A selective permeable membrane sac filled with water and large molecules of starch is suspended in a break of distilled water then water will enter into the sack and it will swell.

This is the process of osmosis in which movement of water molecules form a solution with high concentration to lower concentration till the equilibrium attain. Starch does not pass through thee selectively permeable membrane.Water moves from outside if the cell to the inside leading to swelling of cells.

Small molecules diffuse faster than larger molecules through a membrane. The movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute.
