Design a controlled experiment to determine the effect of hot, dry air on head lice. In your experimental design, be sure to: • state the hypothesis to be tested in the experiment [1]
• state one way the control group will be treated differently from the experimental group [1]
• state one result of the experiment that would support the hypothesis [1]

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.  

golgi body just took the test on edge

well, i believe that the answer is 2. : 3

i think the answer is c hope this
