4. A triangular scarf has sides measuring 10cm, 12cm, and 15cm. What is its perimeter?
- A. 27cm

5. Which blood type is a universal donor?
- A. A
- B. B
- C. AB
- D. O
Correct answer: D
Rationale: Rationale: Blood type O is considered the universal donor because individuals with type O blood can donate red blood cells to individuals with any ABO blood type (A, B, AB, or O) without causing an adverse reaction. This is because type O blood lacks A or B antigens on the surface of red blood cells, which helps minimize the risk of an immune response when transfused into individuals with different blood types. Therefore, type O blood is in high demand for blood transfusions in emergency situations when the recipient's blood type is unknown or when there is a shortage of specific blood types.
6. Which neurotransmitter is associated with mood regulation, sleep, and appetite?
- A. Acetylcholine
- B. Dopamine
- C. Serotonin
- D. GABA (Gamma-aminobutyric acid)
Correct answer: c
Rationale: The correct answer is C: Serotonin. Serotonin is a neurotransmitter that plays a crucial role in mood regulation, sleep, and appetite. It is often referred to as the 'feel-good' neurotransmitter because it helps regulate mood and emotional well-being. Serotonin is also involved in controlling sleep patterns and appetite, making it essential for maintaining a healthy balance in these areas. Acetylcholine is mainly associated with muscle movement and memory, while dopamine is linked to pleasure and reward pathways. GABA is an inhibitory neurotransmitter that helps reduce neuronal excitability. Therefore, serotonin is the neurotransmitter most closely associated with mood regulation, sleep, and appetite.
