1. state one difference between the processes of egestion and excretion.

Explanation:

• Question 9: Synthesis is the process of creating complex substances from simpler ones. Insulin is a complex protein, and its manufacture in the pancreas is an example of synthesis.
• Question 10: Digestion is a catabolic process. In digestion, large, complex food molecules (like proteins, carbohydrates, and fats) are broken down into smaller, simpler molecules (such as amino acids, simple sugars, and fatty acids) that can be absorbed by the body.
• Essay Question: Egestion is the removal of undigested food (feces) from the body. Excretion is the removal of metabolic waste products (such as urea, carbon dioxide) produced by cells during normal metabolic processes.

Answer:

• Question 9: (3) synthesis
• Question 10: (1) Large molecules are broken into small molecules.
• Essay Question: Egestion is the elimination of undigested food, while excretion is the removal of metabolic waste.
