1. What pigment is responsible for the yellow color of bananas?

Correct answer: D

Rationale: Carotene is the pigment responsible for the yellow color of bananas. It belongs to a group of plant pigments called carotenoids, which are responsible for giving fruits and vegetables their vibrant colors, including the yellow hue of bananas. Potassium, calcium, and phosphorus are essential minerals found in bananas but are not responsible for their yellow color.

2. Where is pseudostratified columnar epithelium primarily found?

Correct answer: C

Rationale: Pseudostratified columnar epithelium is a type of epithelial tissue found in the respiratory tract, including the lining of the trachea and bronchi. It is also found in the male reproductive system and parts of the auditory tube and external ear canal. Among the options provided, the external ears (option C) are the most relevant location for pseudostratified columnar epithelium. Skeletal muscle (option A) is primarily composed of muscle fibers, not epithelial tissue. The bony skeleton (option B) is composed of bone tissue. The bloodstream (option D) consists of blood cells and plasma, not epithelial tissue.

3. What is the muscular sac that stores urine until it is released from the body known as?

Correct answer: B

Rationale: The bladder is the muscular sac that stores urine until it is released from the body. It acts as a reservoir for urine until it is eliminated through the urethra. The urethra is the tube responsible for carrying urine from the bladder to the outside. The ureter transports urine from the kidneys to the bladder. The nephron is the structural and functional unit of the kidney involved in the filtration of blood and urine production. Therefore, the correct answer is the bladder, as it specifically fulfills the function of storing urine before its elimination.

4. What property of a substance refers to its ability to be drawn into thin wires?

Correct answer: B

Rationale: Ductility is the property of a substance that allows it to be drawn into thin wires without breaking. Conductivity refers to the ability of a substance to conduct electricity or heat, not to be drawn into wires. Viscosity is the measure of a fluid's resistance to flow, not related to the ability to be drawn into wires. Malleability is the property of a substance that allows it to be hammered or rolled into thin sheets, not specifically related to being drawn into wires. Therefore, the correct property for the ability to be drawn into thin wires is ductility.

5. Which structure of the endocrine system is responsible for maturing T cells?

Correct answer: C

Rationale: The thymus is the primary gland responsible for the maturation of T cells in the immune system. T cells are a type of white blood cell involved in the immune response. The hypothalamus is primarily involved in hormone regulation and maintaining homeostasis. The pineal gland is responsible for secreting melatonin and regulating the sleep-wake cycle. The thyroid gland plays a key role in metabolism regulation through the production of thyroid hormones. Therefore, the correct answer is the thymus because it is specifically associated with the maturation of T cells, making it essential for proper immune function.
