Red blood cells need iron. They store iron and typically contain more iron than the fluid around them does. Which

action would show the blood cells doing active transport?

O pushing iron out

O bringing iron in

O swelling

O shrinking

pushing iron out

Explanation:

Excess iron will be push out of the cell to regulate the internal environment of cell, this active transport involve osmosis.

if this type of reaction occur in a plant cell, the plant cell will shrink which may/will leads to death of the plant.

Hope it is helpful

don't mind my grammatical blunders.

Thank you.

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.  

the titanic would be the correct answer
