1. Identify the type of error in the sentence "They went to the store, and bought groceries, then went home."

• A. Run-on sentence
• B. Comma splice
• C. Dangling modifier
• D. Subject-verb agreement

Correct answer: A

Rationale: The sentence combines two independent clauses without proper punctuation, forming a run-on sentence.

2. Discern the INCORRECT function of the liver.

• A. Bile production, aiding digestion.
• B. Blood protein synthesis, such as albumin.
• C. Glucose storage for energy regulation.
• D. Filtration of waste products from the blood.

Correct answer: D

Rationale: Rationale: A) Correct - The liver produces bile, which aids in the digestion and absorption of fats in the small intestine. B) Correct - The liver is responsible for synthesizing blood proteins, including albumin, which helps maintain osmotic pressure in the blood. C) Correct - The liver stores glucose in the form of glycogen and helps regulate blood sugar levels by releasing glucose when needed. D) Incorrect - The liver does not filter waste products from the blood. Instead, the kidneys are responsible for filtering waste products from the blood and excreting them in the form of urine.

3. Which hormone, produced by the pituitary gland, stimulates the growth and development of bones, muscles, and organs?

• A. Growth hormone (GH)
• B. Thyroid-stimulating hormone (TSH)
• C. Prolactin
• D. Follicle-stimulating hormone (FSH)

Correct answer: A

Rationale: The correct answer is A: Growth hormone (GH). Growth hormone is produced by the pituitary gland and plays a crucial role in stimulating the growth and development of bones, muscles, and organs in the body. It promotes cell division, protein synthesis, and overall growth. Thyroid-stimulating hormone (TSH) stimulates the thyroid gland to produce thyroid hormones, prolactin is involved in milk production after childbirth, and follicle-stimulating hormone (FSH) is responsible for the growth and maturation of ovarian follicles in females and sperm production in males, but they do not directly impact the growth and development of bones, muscles, and organs. Therefore, growth hormone is the hormone specifically known for its role in promoting growth and development in these areas.

4. A pressure vessel has a cylindrical body (diameter 10cm, height 20cm) with hemispherical ends (same diameter as the cylinder). What is its total surface area?

• A. 785 sq cm
• B. 1130 sq cm
• C. 1570 sq cm
• D. 2055 sq cm

Correct answer: D

Rationale: Calculate the surface area of the cylinder (base + lateral surface) and two hemispheres. Add them all up for the total surface area.

5. What is the outermost layer of the dermis, rich in collagen and elastin fibers that provide elasticity to the skin?

• A. Papillary layer
• B. Reticular layer
• C. Stratum basale
• D. Stratum corneum

Correct answer: A

Rationale: The correct answer is A: Papillary layer. The papillary layer is the outermost layer of the dermis and is rich in collagen and elastin fibers. These fibers provide elasticity to the skin, helping it maintain its structure and flexibility. The reticular layer, although deeper in the dermis, is not the outermost layer and is primarily responsible for providing strength and support to the skin. The stratum basale and stratum corneum are layers of the epidermis, not the dermis. The stratum basale is the deepest layer of the epidermis where new skin cells are formed, while the stratum corneum is the outermost layer of the epidermis composed of dead skin cells. Understanding the different layers of the skin is essential for comprehending its functions and properties.

6. What property of a wave determines its pitch in sound waves?

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

Correct answer: B

Rationale: The pitch of a sound wave is determined by its frequency. Frequency refers to the number of cycles of a wave that occur in a given time period. Higher frequencies correspond to higher pitches, while lower frequencies correspond to lower pitches. Amplitude refers to the intensity or loudness of a sound wave, wavelength is the distance between two consecutive points in a wave, and speed is the rate at which a wave travels through a medium.
