PLEASE HELP FAST Valerie is preparing a blood sample for analysis. She wants to separate the solid red blood cells and obtain only the liquid portion, called plasma. The red blood cells are too small to filter out, but are denser than the plasma.

Describe the steps Valerie could take to separate the blood sample.

NO SAMPLE RESPONSE

m=9

step-by-step explanation:

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

catya your not at all which answer i've seen you do this on another question!

it is stable as it is in group 0 which have full outer shells of electrons
