Water potential (ψ) can be thought of as the tendency for water to move from one place to another. in plants, it is made up mainly of solute potential and pressure potential. hypothetical plant cells a and b are adjacent to each other. the solute potential (ψs) of cell a is −0.35 mpa, and its pressure potential (ψp) is +0.15 mpa. the solute potential (ψs) of cell b is −0.30 mpa, and its pressure potential (ψp) is +0.05 mpa. in which direction will net water movement occur?

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?

Ateacher gives students four liquids commonly found in the kitchen - vinegar, apple juice, dish detergent, and milk - and ph indicator strips, which measure acidity. the teacher asks the students to put the liquids in order from most acidic to most basic. what type of investigation could the students conduct to determine the correct order for the liquids?
