1. What is the scientific name for the kneecap?

• A. Patella
• B. Femur
• C. Tibia
• D. Fibula

Correct answer: A

Rationale: The correct answer is A: Patella. The patella is the scientific term for the kneecap, a small, flat, triangular bone situated in front of the knee joint. The femur, tibia, and fibula are also bones in the leg, but they are not synonymous with the kneecap. The femur is the thigh bone, the tibia is the shin bone, and the fibula is the outer lower leg bone. Therefore, the correct term for the kneecap specifically is the patella.

2. Which of the following is used to record the measurable electrical activity of the brain?

• A. CAT scan
• B. MRI scan
• C. Electroencephalogram (EEG)
• D. X-ray

Correct answer: C

Rationale: The correct answer is an Electroencephalogram (EEG). An EEG is specifically designed to record the measurable electrical activity of the brain. It does so by using small, flat metal discs (electrodes) attached to the scalp to detect brain activity. This test is crucial in diagnosing various conditions like seizures, epilepsy, head injuries, dizziness, headaches, and brain tumors. The other options, CAT scan, MRI scan, and X-ray, are imaging techniques that do not directly measure the brain's electrical activity. CAT scan and MRI scan provide detailed images of the brain's structure, while X-ray is more suited for visualizing bone structures or dense tissues.

3. Which of the following reagents can be used to convert a primary alcohol to an alkyl halide?

• A. HI
• B. H2O
• C. NaOH
• D. SOCl2

Correct answer: D

Rationale: SOCl2 (thionyl chloride) is commonly used to convert primary alcohols to alkyl halides through an SN2 mechanism. Thionyl chloride reacts with the alcohol to form an alkyl chloride. HI (hydroiodic acid) is typically used to convert alcohols to alkyl iodides specifically, not alkyl halides in general. H2O (water) and NaOH (sodium hydroxide) are not reagents used for converting alcohols to alkyl halides. Therefore, the correct answer is SOCl2 as it facilitates the conversion of primary alcohols to alkyl halides, unlike the other options provided.

4. Adipose tissue, commonly known as fat, primarily functions in:

• A. Support
• B. Insulation
• C. Energy storage
• D. All of the above

Correct answer: D

Rationale: Adipose tissue, also known as fat, serves multiple essential functions in the body. It provides support by cushioning and protecting organs, acts as an insulator to help regulate body temperature, and serves as a major energy storage site by storing excess energy in the form of triglycerides. Therefore, all the options (support, insulation, and energy storage) are correct functions of adipose tissue, making 'All of the above' the correct answer. Choices A, B, and C are all individually valid functions of adipose tissue, but to encompass the comprehensive role of adipose tissue, 'All of the above' is the most accurate option.

5. Which of the following is NOT a symptom of asthma, a chronic respiratory condition?

• A. Wheezing
• B. Difficulty breathing
• C. Chest tightness
• D. Fever

Correct answer: D

Rationale: The correct answer is 'Fever.' Fever is not a symptom commonly associated with asthma. Asthma symptoms typically include wheezing, difficulty breathing, and chest tightness due to inflammation and narrowing of the airways. Fever is more commonly seen in conditions such as infections or inflammatory diseases rather than asthma. Choices A, B, and C are common symptoms of asthma and are related to the constriction and inflammation of the airways, leading to breathing difficulties and chest discomfort.
