Answer

Brief Explanations:

  • Question 4: Dehydration synthesis is a chemical reaction where a water molecule is removed to form a larger molecule. Sucrose is formed by joining two monosaccharides through dehydration synthesis.
  • Question 5: LDL (low - density lipoprotein) is associated with "bad" cholesterol and can contribute to atherosclerotic changes in blood vessels. HDL is "good" cholesterol. There is no VHDL in the common lipoprotein classifications.
  • Question 6: Proteins, lipids, and nucleic acids are major groups of organic substances in the human body. Salts are inorganic compounds.

Answer:

  • Question 4: D. dehydration synthesis
  • Question 5: B. LDL
  • Question 6: B. Salts
