Anatomy

1. The large intestine absorbs water and electrolytes from digested food material. What waste product remains after water absorption and is eventually eliminated from the body?

Correct answer: D

Rationale: The large intestine is responsible for absorbing water and electrolytes from digested food material. As the waste material moves through the large intestine, most of the water is absorbed, leaving behind waste products known as feces. Feces consist of indigestible material, bacteria, and some remaining waste products. This waste is eventually eliminated from the body through the process of defecation. Chyme refers to the semi-fluid mass of partially digested food that moves from the stomach to the small intestine. Bolus is a term used to describe a mass of chewed food ready to be swallowed. Glucose is a simple sugar that is absorbed in the small intestine and used as an energy source. Therefore, the correct answer is D: Feces.

2. Which word is misspelled?

Correct answer: D

Rationale: "Indelible" is spelled correctly, while "circumstance" should be "circumstance."

3. Which element makes up the majority of the Earth's atmosphere?

Correct answer: A

Rationale: Nitrogen is the most abundant gas in the Earth's atmosphere, crucial for plant life and maintaining the planet's temperature balance.

4. he adrenal cortex produces a group of steroid hormones called corticosteroids. What is a MAJOR function of corticosteroids?

Correct answer: B

Rationale: The correct answer is B: 'Control blood pressure and electrolyte balance.' Corticosteroids, produced by the adrenal cortex, play a major role in regulating blood pressure and electrolyte balance in the body. These hormones, such as aldosterone, act on the kidneys to control the reabsorption of sodium and water, which in turn affects blood pressure and electrolyte levels. While corticosteroids can have effects on other physiological processes, their primary function is to regulate blood pressure and electrolyte balance, making option B the most appropriate choice in this context.

5. A decorative box has a rectangular base (20cm by 15cm) and a hemispherical top with the same diameter as the base. What is the total surface area of the box (excluding the base)?

Correct answer: C

Rationale: Calculate the surface area of the lateral sides and the hemisphere, then add them up.

6. Which of the following is a common property of both acids and bases?

Correct answer: d

Rationale: Both acids and bases conduct electricity when dissolved in water. The other choices are specific to either acids or bases.
