Wich type of symbios is each of these E. coli bacteria live in massive quantities in the large intestine of humans. They produce Vitamin K which aids in blood clotting.

Small spruce and fir trees grow in the shade of aspen trees in the forest. They would not grow as well in direct sunlight.

Bighorn sheep take in worm eggs when grazing. The worm egg hatches in the intestine and the larvae migrate to muscle tissue. When the larvae mature, they bore into capillaries and float to the lungs, where they form cysts. Large numbers of these can affect the breathing of the bighorn sheep.

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.
