Astudent states that this structural formula represents a hydrocarbon bhh h-c-c-0-h hh is the student correct? yes, a hydrocarbon is any compound that contains a carbon backbone, yes, a hydrocarbon is any compound that contains hydrogen and oxygen, no, a hydrocarbon contains only carbon and hydrogen atoms, no a hydrocarbon contains at least one double or triple bond

the genotypes would be 50% bb and 50% bb

the phenotypes would be 50% brown and 50% white. hope this : )

i'd say that the moon rock is about 2.2 billion years old.

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.
