Analyze Question 9

The chemical formula for water is \(H_2O\). It consists of two hydrogen atoms and one oxygen atom. Due to differences in electronegativity, the hydrogen atoms carry a partial positive charge, while the oxygen atom carries a partial negative charge. Therefore, the two positively charged atoms are hydrogen, and the negatively charged atom is oxygen.

Analyze Question 10

Water travels upward through the xylem of tall trees against gravity. This movement is driven by transpiration pull and facilitated by capillary action, which relies on the cohesive forces between water molecules and adhesive forces between water molecules and the xylem walls. Among the choices, capillary action is the process that directly describes this movement.
