Answer

Brief Explanations:

  • For question 19: Cells are the basic units of structure and function in all living organisms, not just plants and animals.
  • For question 20: Weathering breaks down rocks and minerals into smaller particles (sediment), and erosion is the process of transporting these sediments. Erosion is not limited to water - bodies, and it usually follows weathering. They are not identical processes.
  • For question 21: During a dust - storm, fine particles are in the air. A face mask or cloth covering helps protect the respiratory system from inhaling these particles. Sunglasses protect the eyes but are not the most essential for overall protection, an umbrella is for rain, and rain boots are for wet ground.

Answer:

  1. a basic unit of structure and function of all living organisms
  2. Weathering creates sediment, which is then transported by erosion.
  3. Face mask or cloth covering
