  31.        They all use cellular respiration to obtain energy.
  32.        They all use photosynthesis to obtain energy.
  33.        They all make their own food.
  34.        They all ingest food.

  59. 11. Do plants break down glucose to obtain energy? (Points : 3)
  60.        No, they make glucose, but they don’t break it down.
  61.        No, they absorb the sun's energy directly.
  62.        No, they absorb energy from the soil.
  63.        Yes, they make glucose and break it down to produce ATP.
  64.  
  65. 12. Your respiratory system removes which waste product from your body? (Points : 3)
  66.        urine
  67.        carbon dioxide
  68.        blood
  69.        oxygen
  70.  
  71. 13. Plants produce which of the following as waste products? (Points : 3)
  72.        oxygen and urine
  73.        carbon dioxide and urine
  74.        carbon dioxide and oxygen
  75.        carbon dioxide and uric acid
  76.  
  77. 14. Waste removal in a flatworm is best described by which of the following statements? (Points : 3)
  78.        Flatworms have an extensive branched system that removes liquid waste.
  79.        Flatworms store waste in their bodies until they die.
  80.        Flatworms process solid, liquid, and gaseous waste in the same body system.
  81.        Flatworms have no specialized waste removal system.
  82.  
  83. 15. Of the statements below, identify the one that best describes the relationship between plants and oxygen. (Points : 3)
  84.        Plants produce oxygen during photosynthesis and they also need oxygen from the air for cellular respiration.
  85.        Plants do not need oxygen because they use carbon dioxide in cellular respiration.
  86.        Plants do not need oxygen because they do not undergo cellular respiration.
  87.        Plants do not need any oxygen from the air because they produce it during photosynthesis.
  88.  
  89. 16. If you were a fish, how would you obtain oxygen? (Points : 3)
  90.        Your body cells would break down water molecules (H2O) and release the oxygen.
  91.        You would take in oxygen gas dissolved in the water through your gills.
  92.        You would inhale oxygen at the surface of the water.
  93.        Oxygen would diffuse across your skin.
  94.  
  95. 17. How does your heart deliver oxygen to your body cells? (Points : 3)
  96.        The heart pumps air throughout your body, delivering it to the cells.
  97.        The heart takes in oxygen from the air.
  98.        The heart breaks down carbon dioxide into carbon and oxygen.
  99.        The heart pumps oxygenated blood to your body cells.
