1. What is the common name for the compound CH₃COOH?

• A. Acetic acid
• B. Formic acid
• C. Butyric acid
• D. Propionic acid

Correct answer: A

Rationale: CH₃COOH is commonly known as acetic acid. The other choices represent different organic acids.

2. What is the purpose of the spindle apparatus in cell division?

• A. To separate sister chromatids
• B. To move chromosomes to opposite poles of the cell
• C. To form a new nuclear envelope around each daughter cell
• D. To synthesize new DNA

Correct answer: B

Rationale: Rationale: The spindle apparatus is a structure composed of microtubules that plays a crucial role in cell division (mitosis and meiosis). Its main purpose is to ensure the proper separation and distribution of chromosomes to opposite poles of the cell during cell division. This process is essential for the formation of two genetically identical daughter cells in mitosis or four haploid daughter cells in meiosis. Option A is incorrect because the separation of sister chromatids specifically refers to the role of the kinetochore fibers within the spindle apparatus. Option C is incorrect because the formation of a new nuclear envelope occurs after the chromosomes have been properly segregated. Option D is incorrect because DNA synthesis does not occur within the spindle apparatus; it takes place during the S phase of the cell cycle.

3. What is the condition called when someone experiences a temporary loss of consciousness due to a lack of blood flow to the brain?

• A. Stroke
• B. Epilepsy
• C. Syncope (fainting)
• D. Multiple sclerosis

Correct answer: C

Rationale: The correct answer is C: 'Syncope (fainting)'. Syncope is the temporary loss of consciousness caused by a temporary drop in blood flow to the brain, leading to a lack of oxygen reaching the brain. This can occur due to various reasons such as dehydration, sudden drop in blood pressure, or emotional stress. A stroke (option A) is a sudden interruption in the blood supply to the brain, leading to brain cell damage. Epilepsy (option B) is a neurological disorder characterized by recurrent seizures. Multiple sclerosis (option D) is a chronic autoimmune disease that affects the central nervous system. Therefore, the correct term for a temporary loss of consciousness due to lack of blood flow to the brain is syncope.

4. Harry is a Unit Manager I the Medical Unit. He is not satisfied with the way things are going

• A. Call for a staff meeting and take this up in the agenda.
• B. Seek help from her manager.
• C. Develop a strategic action on how to deal with these concerns.
• D. Ignore the issues since these will be resolved naturally.

Correct answer: A

Rationale: Choosing option A, 'Call for a staff meeting and take this up in the agenda,' is the best course of action for Harry as a Unit Manager. By calling for a staff meeting, Harry can openly address his concerns with the team, gather input from team members, and work collaboratively to find solutions. This approach promotes transparency, communication, and teamwork, which are essential in resolving issues within a unit. Seeking help from his manager, as suggested in option B, may be necessary in some cases, but initiating a discussion with the staff first allows for a more inclusive problem-solving process. Developing a strategic action, as in option C, is important, but involving the team in this process through a staff meeting is crucial for buy-in and implementation. Ignoring the issues, as in option D, is never a productive approach as unresolved issues can escalate and impact team morale and performance. Therefore, option A is the most effective and proactive way for Harry to address hi

5. The network of vessels and ducts responsible for draining excess fluid and waste products from tissues is the:

• A. Circulatory system
• B. Digestive system
• C. Lymphatic system
• D. Respiratory system

Correct answer: C

Rationale: The correct answer is C: Lymphatic system. The lymphatic system is a network of vessels and ducts that play a crucial role in maintaining fluid balance in the body by draining excess fluid and waste products from tissues. Unlike the circulatory system (A), which primarily transports blood, the lymphatic system is specifically designed for this drainage function. The digestive system (B) is responsible for breaking down food and absorbing nutrients, while the respiratory system (D) is involved in the exchange of gases. Therefore, the lymphatic system is the correct answer for this question as it is uniquely tasked with managing tissue fluid balance and waste removal.

6. A children's toy consists of a half cylinder (diameter 10cm, height 8cm) attached to a cube with side lengths of 5cm. What is the total volume of the toy?

• A. 125 cu cm
• B. 200 cu cm
• C. 275 cu cm
• D. 350 cu cm

Correct answer: C

Rationale: Calculate the volume of the half cylinder and the cube separately, then add them up.
