5.2.7 Journal: Finding Information About Disease

1. Go to www. cdc. gov. You will find an A - Z index across the top of the page. Click on the letter that
corresponds to a disease you are interested in learning more about. List six facts from the CDC about symptoms, transmission, and treatment of the disease you selected. (6 points)

2. Research information about how common the disease you selected is. Analyze this information. How has the number of cases changed over time? (6 points)

3. Reflect on using the CDC as a source for information. Were you easily able to find the information that you needed? Is the information useful? Why or why not? (8 points)

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.
