Juan is studying fossils. his teacher wrote the following statements on the board and asked the students to put them in the correct order to describe how fossils are formed. 1. minerals seep into the organism’s body and replace it with stone. 2. the organism completely decomposes, leaving behind an imprint. 3. an organism dies and its body is covered with a layer of sediment. 4. time passes, and sediment layers continue to build up on the organism. which is the correct order of events for fossil formation?

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.  

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
