Explanation:

• Question 45: Responsiveness is the ability of organisms to respond to external and internal stimuli. Metabolism is about chemical reactions in the body, homeostasis is maintaining a stable internal environment, diatomic refers to molecules with two atoms, and adaptation is a long - term evolutionary change.
• Question 46: Pure water has a pH of 7, which is neutral. pH values less than 7 are acidic (e.g., 6), and values greater than 7 are basic (e.g., 12, 14). A pH of 0 is extremely acidic.
