Question

question 1
which of the following molecules is most abundant in the cells of the human body?
nucleotides
lipids
amino acids
water

question 2
a water molecule bonds with other water molecules with weak, ______ bonds.
oxygen
aquatic
ionic
hydrogen

Explanation:

Analyze cellular abundance

Water is the most abundant molecule in living cells, making up approximately 70% of a cell's total mass. Other organic molecules like lipids, amino acids, and nucleotides are present in much smaller percentages.

Identify intermolecular forces in water

Water molecules are polar, with a partial negative charge on oxygen and partial positive charges on hydrogen. The weak electrostatic attraction between the hydrogen of one water molecule and the oxygen of another forms a hydrogen bond.

Answer:

Question 1

• Nucleotides
• Lipids
• Amino acids
• Water (Correct answer)

Question 2

• oxygen
• aquatic
• ionic
• hydrogen (Correct answer)
