Answer

Brief Explanations:

  1. In symbiotic relationships, mutualism is when both organisms benefit.
  2. A tick on a dog is a parasitic relationship example.
  3. Plants use photosynthesis to make sugars.
  4. Cellular respiration breaks down food for ATP.
  5. The water - cycle involves evaporation (liquid to gas), condensation (gas to liquid), precipitation (rain, snow etc.), and transpiration (plants releasing water vapor).
  6. Weight changes based on location due to gravity differences, while mass is constant.
  7. The density formula is $\rho=\frac{m}{V}$, where $\rho$ is density, $m$ is mass, and $V$ is volume.
  8. Burning wood is a chemical change as new substances are formed.
  9. The law of conservation of mass states mass is not created or destroyed.
  10. A solid has a definite volume and a definite shape.
  11. A gas has more kinetic energy as its particles move more freely than in a liquid.
  12. The smallest unit of an element is an atom.
  13. Salt water is a mixture as it contains salt and water which can be separated physically.
  14. Protons in an atom have a positive charge.
  15. The periodic table is arranged by increasing atomic number.
  16. Horizontal rows on the periodic table are called periods.
  17. Vertical columns on the periodic table are called groups or families.
  18. Oxygen has 8 protons.
  19. Most common oxygen - 16 has 8 neutrons.
  20. In a neutral oxygen atom, there are 8 electrons.
  21. The material a wave travels through is called the medium.
  22. A sound wave is an example of a mechanical wave.
  23. Parts of a wave include crest (highest point), trough (lowest point), wavelength (distance between two identical points), amplitude (height from rest to crest or trough).

Answer:

  1. Mutualism
  2. A tick on a dog
  3. Photosynthesis
  4. Cellular respiration
  5. Evaporation: Liquid water turns to water vapor. Condensation: Water vapor turns to liquid droplets. Precipitation: Water falls as rain, snow, etc. Transpiration: Plants release water vapor.
  6. Weight
  7. $\rho = \frac{m}{V}$
  8. Burning wood
  9. Law of conservation of mass
  10. Definite; definite
  11. Gas
  12. Atom
  13. Mixture
  14. Proton
  15. By increasing atomic number
  16. Periods
  17. Groups or families
  18. 8
  19. 8 (for oxygen - 16)
  20. 8
  21. Medium
  22. Sound wave
  23. Crest, trough, wavelength, amplitude
