A student has a beaker of a clear and colorless solution. Which method would quickly reveal if the solution was saturated or unsaturated? O A. Add more solvent to the beaker. O B. Add heat to the solution and stir. O C. Allow some of the solvent to evaporate over time. O D. Add a crystal of the same solute to the beaker.​

B. Add heat to the solution and stir.

Explanation:

Adding heat and stirring the solution will increase the rate in which it dissolves. After most of the particles have dissolved, it will be visible at the bottom of the container whether it was saturated or not.

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.  

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
