The theory says that the big bang produced the chemical elements hydrogen and helium. what evidence supports this? you find an abundance of both hydrogen and helium in all matter.

a. you find an abundance of both hydrogen and helium in all matter.

b. the composition of stars is mostly hydrogen.

c. astronomers found primordial gases with the expected ratio of helium to hydrogen.

d. primordial hydrogen gas was found and there is an abundance of both of these elements.

Astronomers found primordial gases with the expected ratio of helium to hydrogen.

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.
