b) strong support for the theory of spontaneous generation
c) that all bacteria are unicellular organisms
d) strong support for the new cell theory

that all cells come from preexisting cells

Explanation:

Louis Pasteur postulate that all living cells come from preexisting cells. Cells are the basic unit of life. All living things are made up of cells that formed through division of the preexisting cells. The scientist cultured cells in a lab. After few days, the mass of cells had increased greatly.

substitution is the answer in this case

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.
