1. What is cystitis an inflammation of?

Correct answer: B

Rationale: Cystitis is an inflammation of the bladder. It is typically caused by a bacterial infection and can lead to symptoms such as frequent urination, pain or burning during urination, and lower abdominal discomfort. The inflammation specifically affects the bladder lining. Choices A, C, and D are incorrect. Kidneys are not the site of inflammation in cystitis; they are associated with conditions like pyelonephritis. Ureters are tubes that connect the kidneys to the bladder, and the urethra is the tube that carries urine from the bladder to outside the body. Therefore, the correct answer is 'Bladder.'

2. Which of the following statements is FALSE regarding the use of qualitative and quantitative data in scientific research?

Correct answer: B

Rationale: The correct answer is B because quantitative data is not inherently more accurate than qualitative data. Both types of data have their strengths and limitations, and the choice of data type depends on the research question and methodology. Quantitative data is collected through numerical measurements and involves statistical analysis. On the other hand, qualitative data focuses on perspectives, behaviors, and meanings and is typically gathered through observation and interviews. While quantitative data provides numerical precision, qualitative data offers in-depth insights into behaviors and perspectives that cannot be quantified, making them equally valuable in scientific research.

3. Which organ is primarily responsible for detoxification in the body?

Correct answer: B

Rationale: The liver is the primary organ responsible for detoxifying chemicals and metabolizing drugs in the body. It plays a crucial role in breaking down toxins, filtering blood, and producing bile, making it essential for overall detoxification processes. The kidney primarily filters waste and excess substances from the blood to form urine. Lungs are responsible for gas exchange, not detoxification. The heart is responsible for pumping blood and does not play a direct role in detoxification processes.

4. Which type of wave does not require a medium for propagation?

Correct answer: D

Rationale: The correct answer is D, Electromagnetic wave. Electromagnetic waves do not require a medium for propagation because they consist of oscillating electric and magnetic fields that can travel through a vacuum. In contrast, transverse and longitudinal waves are mechanical waves that require a medium (solid, liquid, or gas) for propagation. Therefore, options A, B, and C are incorrect as they are all types of mechanical waves that necessitate a medium for transmission.

5. How does AIDS impair the immune system?

Correct answer: A

Rationale: AIDS targets and destroys Helper T-Cells, which play a crucial role in coordinating the immune response. By affecting these cells, AIDS prevents the activation of other important immune cells like Cytotoxic T-Cells or B-Cells. This disruption in the immune system's communication and response mechanisms leads to immune system failure and increased vulnerability to infections. Choices B and C are incorrect because they refer to the role of IgE in allergic reactions, which is not directly related to how AIDS impairs the immune system. Choice D is also incorrect as Helper T-Cells being destroyed in AIDS is not about deceiving the body into attacking itself, but rather the direct impact on immune system function.
