Reading

1. What is the main point of the passage?

Correct answer: C

Rationale: The passage clearly identifies human activities as the cause of climate change and emphasizes the need for global action, aligning with C.

2. Lysosomes are known as "suicide bags" of the cell. What enzymes do they contain?

Correct answer: A

Rationale: Lysosomes are membrane-bound organelles containing hydrolytic enzymes responsible for breaking down various macromolecules, cellular waste, and foreign substances. These enzymes perform hydrolysis, a process where water molecules are used to break down larger molecules into smaller components. This function earned lysosomes the nickname 'suicide bags' as they can initiate cell death (apoptosis) by releasing their enzymes when needed. Ligases, transferases, and oxidoreductases are enzymes with different functions such as forming bonds, transferring molecules, and catalyzing redox reactions, respectively, which are not typically found in lysosomes. Therefore, the correct answer is A: 'Hydrolytic enzymes.'

3. What is the name of the microscopic finger-like projections that increase the surface area for absorption in the small intestine?

Correct answer: C

Rationale: Rationale: A) Goblet cells: Goblet cells are specialized cells that secrete mucus to protect the lining of the digestive tract. While important for maintaining the health of the intestines, goblet cells do not increase the surface area for absorption in the small intestine. B) Paneth cells: Paneth cells are specialized cells found in the small intestine that secrete antimicrobial peptides. They play a role in protecting the intestinal stem cells and maintaining the gut microbiota balance, but they do not increase the surface area for absorption. C) Villi: Villi are microscopic finger-like projections found in the small intestine that increase the surface area available for absorption of nutrients. Each villus contains blood vessels and lacteals (lymphatic vessels) that help absorb nutrients from digested food. D) Crypts of Lieberkühn: Crypts of Lieberkühn are small pits located between the villi

4. What type of enzyme breaks down carbohydrates like starches and sugars in the mouth?

Correct answer: C

Rationale: The correct answer is C: Amylase. Amylase is an enzyme specifically responsible for breaking down carbohydrates like starches and sugars in the mouth. It is produced by both the salivary glands and the pancreas. Pepsin (A) is an enzyme that breaks down proteins in the stomach, lipase (B) breaks down fats, and trypsin (D) is another enzyme that digests proteins but is produced in the pancreas and works in the small intestine. Therefore, amylase is the enzyme that targets carbohydrates in the mouth, aiding in the initial digestion process of these nutrients.

5. She notes that there is an increasing unrest of the staff due to fatigue brought about by

Correct answer: C

Rationale: The correct answer is C: 'Develop a plan and implement it.' In the given scenario, the staff is experiencing unrest due to fatigue, which is a serious issue affecting their well-being and productivity. By developing a plan to address the fatigue issue and implementing it effectively, the organization can provide necessary support to the staff, improve working conditions, and enhance overall morale and performance. This proactive approach is crucial in maintaining a healthy work environment and ensuring the well-being of the staff members. Options A, B, and D do not directly address the root cause of fatigue and unrest among the staff, making them less suitable answers.

6. The fluid-filled sacs that cushion the brain within the skull are called:

Correct answer: B

Rationale: The correct answer is B: Cerebrospinal fluid. Cerebrospinal fluid is a clear, colorless fluid that surrounds the brain and spinal cord, acting as a cushion to protect the central nervous system from injury. Meninges (Option A) are the protective membranes that cover the brain and spinal cord, while the dura mater (Option C) and arachnoid mater (Option D) are specific layers of the meninges. However, cerebrospinal fluid is the fluid-filled sac that directly cushions the brain within the skull, making it the most appropriate answer for this question.
