The components of blood can be separated by spinning them at high speed. Figure I shows a tube of blood that has been separated in this way.

Plasma

Explanation:

We don't have the figure, but I think the answer is probably plasma.

Blood plasma is the fluid that blood cells are suspended in. When blood is spun at high speed, the cells separate away from the plasma into different layers because of their different weights and shapes.

Plasma is liquid portion of blood. It transports nutrients and wastes and maintains  homeostasis.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.  

i won't lie i don't know so go online and ask google thats what i do
