the chemical process in which a compound unites with water and then splits into simpler compounds is called
dehydration synthesis.
hydrolysis.
emulsification.
none of the above.

Explanation:

Question 3

To determine the percentage of blood flow to the liver from the hepatic portal system, we rely on anatomical knowledge: the hepatic portal system supplies about 80% of the liver's blood flow (the remaining ~20% comes from the hepatic artery).

• Dehydration synthesis: Removes water to form bonds (e.g., in polymer formation), so not matching.
• Hydrolysis: Involves adding water to break a compound into simpler parts, which matches the described process.
• Emulsification: Breaks fats into droplets (no splitting into simpler compounds via water), so incorrect.

Answer:

C. 80%
