3. What term describes the maximum displacement of particles from their rest position in a wave?

• A. Frequency
• B. Wavelength
• C. Amplitude
• D. Velocity

Correct answer: C

Rationale: The term that describes the maximum displacement of particles from their rest position in a wave is called the amplitude. Amplitude is a measure of the strength or intensity of a wave and is represented by the height of the wave from the rest position to the crest (or trough) of the wave. Frequency (A) refers to the number of complete wavelengths that pass a point in a given time, wavelength (B) is the distance between two consecutive crests (or troughs) of a wave, and velocity (D) is the speed of the wave.

4. Which part of the brain is responsible for regulating body temperature, hunger, and thirst, and is considered a key player in the endocrine system?

• A. Amygdala
• B. Hippocampus
• C. Hypothalamus
• D. Thalamus

Correct answer: c

Rationale: The correct answer is C: Hypothalamus. The hypothalamus is a small region in the brain that plays a crucial role in maintaining homeostasis by regulating body temperature, hunger, and thirst. It also serves as a key player in the endocrine system by controlling the release of hormones from the pituitary gland. The amygdala is responsible for processing emotions and memory, the hippocampus is involved in memory formation and retrieval, and the thalamus acts as a relay station for sensory information. Therefore, the hypothalamus is the most appropriate choice for the functions described in the question.

5. What property of matter remains constant regardless of changes in gravity?

6. The structural and functional unit of the kidney responsible for filtering blood is the:

• A. Nephron
• B. Ureter
• C. Urethra
• D. Bladder

Correct answer: A

Rationale: The correct answer is A, Nephron. The nephron is the structural and functional unit of the kidney responsible for filtering blood. It consists of the glomerulus, renal tubule, and collecting duct. The nephron's filtration process plays a crucial role in removing waste products, regulating electrolyte balance, and maintaining blood pressure. The other options, B: Ureter, C: Urethra, and D: Bladder, are not responsible for filtering blood. The ureter transports urine from the kidneys to the bladder, the urethra is responsible for urine excretion from the bladder, and the bladder stores urine before excretion. Therefore, the nephron is specifically designed for the filtration process within the kidney.
