Lizzie loves to stargaze at night. she has noticed that the moon appears to change shape over the course of the month, and she wants to investigate why this happens. she hypothesizes that the relationship of the sun, earth, and moon creates shadows on the moon. she sets up an experiment with a light bulb to represent the sun, a large beach ball to represent earth, and a smaller foam ball to represent the moon. she researches the position of the sun, earth, and moon at different times of a month and makes a model of the entire system.

a "theory" a suggestion that is not 100 % accurate, or a figure. some people say its a theory because they of all the passed theory's about one subject. it depends sometimes theory might be accurate and sometimes they are.

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.  

c is the answer. hope this
