1. What is the term for the process of breaking a large molecule into smaller fragments by applying heat?

• A. Polymerization
• B. Hydrogenation
• C. Isomerization
• D. Pyrolysis

Correct answer: D

Rationale: Pyrolysis is the process of breaking down large molecules into smaller fragments by applying heat. The other choices involve different chemical processes.

2. Which property of a substance refers to its ability to be stretched into thin wires?

• A. Conductivity
• B. Viscosity
• C. Ductility
• D. Malleability

Correct answer: c

Rationale: Ductility refers to a substance's ability to be stretched into thin wires without breaking.

3. Bile, stored in the gallbladder, aids in the digestion of:

• A. Carbohydrates
• B. Proteins
• C. Fats
• D. Vitamins

Correct answer: C

Rationale: The correct answer is C: "Fats." Bile, produced by the liver and stored in the gallbladder, plays a crucial role in the digestion and absorption of fats. When you consume fatty foods, bile is released into the small intestine to help break down the fats into smaller droplets, making it easier for enzymes to digest them. This process allows the body to absorb essential fatty acids and fat-soluble vitamins. Carbohydrates are mainly digested by enzymes like amylase in the mouth and small intestine, while proteins are broken down by enzymes like pepsin and trypsin. Vitamins are not directly digested by bile but are absorbed along with fats in the small intestine. Therefore, the correct answer is C, as bile aids in the digestion of fats.

4. What is the process by which the body reabsorbs water from the large intestine?

• A. Dehydration
• B. Osmosis
• C. Filtration
• D. Secretion

Correct answer: B

Rationale: Rationale: - Dehydration (Option A) refers to the condition of having insufficient water in the body, not the process of water reabsorption in the large intestine. - Osmosis (Option B) is the movement of water across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. In the large intestine, water is reabsorbed through osmosis to maintain the body's fluid balance. - Filtration (Option C) is a process where a liquid or gas passes through a filter to separate the components. It is not the primary mechanism for water reabsorption in the large intestine. - Secretion (Option D) is the release of substances from cells, but it is not the process by which the body reabsorbs water from the large intestine. Therefore, the correct process by which the body reabsorbs water from the large intestine is

5. What literary device is used in the line "The sea whispered secrets to the shore"?

• A. Alliteration
• B. Personification
• C. Onomatopoeia
• D. Hyperbole

Correct answer: B

Rationale: The sentence gives human qualities to the sea, like whispering, creating personification.

6. Which of the following organs is NOT directly involved in urine production?

• A. Kidneys
• B. Urethra
• C. Lungs
• D. Bladder

Correct answer: C

Rationale: The correct answer is C: Lungs. The lungs are not directly involved in urine production. The kidneys are responsible for filtering waste products from the blood to create urine. The urethra is the tube that carries urine from the bladder out of the body. The bladder serves as a temporary storage reservoir for urine. In contrast, the lungs are primarily responsible for the exchange of gases, such as oxygen and carbon dioxide, during respiration and are not directly involved in the process of urine production.
