1. Which of the following is NOT a function of the nervous system?

A. Detecting touch
B. Regulating body temperature
C. Producing insulin
D. Controlling muscle movement

Correct answer: C

Rationale: The correct answer is C: 'Producing insulin.' The nervous system is responsible for detecting touch (option A), regulating body temperature (option B), and controlling muscle movement (option D). Insulin production is actually regulated by the endocrine system, specifically the pancreas. Insulin helps regulate blood sugar levels, which is not a function of the nervous system. It is important to differentiate between the roles of the nervous system and the endocrine system in maintaining bodily functions.

2. What is the relationship between the speed of a wave, its frequency, and wavelength in a given medium?

A. Speed = Frequency Ã— Wavelength
B. Speed = Frequency Ã· Wavelength
C. Speed = Frequency + Wavelength
D. Speed = Frequency - Wavelength

Correct answer: a

Rationale: In a given medium, the speed of a wave equals the product of its frequency and wavelength.

3. Which molecule is responsible for storing and providing a quick source of energy during short bursts of intense physical activity, such as weightlifting or sprinting?

A. ATP (Adenosine Triphosphate)
B. Glucose
C. Myoglobin
D. Lactic Acid

Correct answer: a

Rationale: The correct answer is A: ATP (Adenosine Triphosphate). ATP is known as the energy currency of the cell and is responsible for storing and providing quick energy during short bursts of intense physical activity. When muscles require immediate energy for activities like weightlifting or sprinting, ATP is broken down to release energy rapidly. Glucose is a source of energy but needs to be converted into ATP before it can be used by the muscles. Myoglobin is a protein that stores oxygen in muscle cells, not energy. Lactic Acid is produced during intense exercise but is not a direct source of quick energy like ATP.

4. What is the main topic of the passage?

A. Benefits of bioremediation in cleaning oil spills.
B. Dangers of microplastics to marine ecosystems.
C. History of plastic production and its global impact.
D. Comparison of different waste management strategies.

Correct answer: B

Rationale: The passage focuses on the specific issue of microplastics in the marine environment and their harmful effects.

5. Histamine, released during an allergic reaction, causes symptoms like:

A. Fever and fatigue
B. Runny nose and itchiness
C. Muscle aches and joint pain
D. Cough and shortness of breath

Correct answer: B

Rationale: The correct answer is B: 'Runny nose and itchiness.' Histamine is a chemical released by the body during an allergic reaction. It causes various symptoms such as itching, sneezing, runny nose, and watery eyes. These symptoms are commonly associated with allergic reactions like hay fever or hives. Fever and fatigue (option A) are not directly caused by histamine release. Muscle aches and joint pain (option C) are not typical symptoms of histamine release during an allergic reaction. Cough and shortness of breath (option D) are more commonly associated with asthma or respiratory allergies rather than histamine release.
