1. Which element is present in household bleach and has disinfectant properties?

• A. Sodium
• B. Chlorine
• C. Fluorine
• D. Iodine

Correct answer: B

Rationale: Chlorine's oxidizing ability makes it effective in killing bacteria and other microorganisms.

2. She is hopeful that her unit will make a big turnaround in the succeeding months. Which of

• A. Wonders why things are not what it used to be
• B. Finds solutions to the problems
• C. Integrate the solutions to his day-to-day activities
• D. Selects the best change strategy

Correct answer: C

Rationale: The correct answer is C: 'Integrate the solutions to his day-to-day activities.' In the given scenario, the individual is hopeful about a turnaround in their unit, indicating a desire for positive change. Option C aligns with this by suggesting that the individual is not only finding solutions to the problems (as in option B) but also integrating these solutions into their daily routines. This integration is crucial for sustained improvement and long-term success, making it the most appropriate choice among the options provided.

3. Which of the following is NOT a method of sterilization?

• A. Autoclave
• B. UV light
• C. Chemical disinfectants
• D. Boiling water

Correct answer: D

Rationale: Rationale: A) Autoclave: An autoclave is a method of sterilization that uses high pressure and steam to kill microorganisms, making it an effective way to sterilize equipment and materials. B) UV light: UV light is a method of sterilization that damages the DNA of microorganisms, preventing them from reproducing and causing infections. C) Chemical disinfectants: Chemical disinfectants are used to kill or inactivate microorganisms on surfaces, but they may not always achieve sterilization, which is the complete destruction of all microorganisms. D) Boiling water: Boiling water is a method of disinfection rather than sterilization. While boiling water can kill many microorganisms, it may not be effective against all types of bacteria, viruses, and spores, making it unsuitable for achieving sterilization. Therefore, the correct answer is D) Boiling water, as it is not a method of sterilization

4. What is the functional group present in aldehydes?

• A. Hydroxyl
• B. Carbonyl
• C. Ester
• D. Amine

Correct answer: B

Rationale: Aldehydes have the functional group -CHO, which is a carbonyl group bonded to a hydrogen atom. The other choices are associated with different functional groups.

5. A birdbath has a hemispherical bowl with a diameter of 30cm. What is its volume?

• A. 675 cu cm
• B. 1350 cu cm
• C. 2700 cu cm
• D. 4050 cu cm

Correct answer: C

Rationale: Use half the formula for a sphere's volume: (2/3) * π * (radius)^3. Calculate the radius (15cm) and substitute: (2/3) * π * (15cm)^3 ≈ 2700 cu cm.

6. Which type of muscle tissue has a unique branching network and is found in the heart?

• A. Skeletal muscle
• B. Cardiac muscle
• C. Smooth muscle
• D. Multifidus muscle

Correct answer: B

Rationale: The correct answer is B - Cardiac muscle. Cardiac muscle is the type of muscle tissue that has a unique branching network and is specifically found in the heart. Unlike skeletal muscle, which is attached to bones and allows for voluntary movement, cardiac muscle is involuntary and contracts to pump blood throughout the body. Smooth muscle is found in organs like the intestines and blood vessels, while the multifidus muscle is a specific muscle in the back. Therefore, cardiac muscle is the appropriate choice in this scenario.
