Anatomy

1. Sweat glands help regulate body temperature by:

Correct answer: C

Rationale: The correct answer is C. Sweat glands help regulate body temperature by releasing a watery fluid that evaporates for cooling. When the body temperature rises, sweat glands produce sweat, which is mostly composed of water and salts. As this sweat evaporates from the skin's surface, it absorbs heat energy from the body, thus cooling it down. This process is essential for maintaining a stable body temperature during physical exertion or exposure to heat. Options A, B, and D are incorrect as sebum produced by sebaceous glands lubricates the skin, blood vessels dilate rather than constrict during sweating to release heat, and the epidermis does not thicken for insulation related to sweat glands.

2. You observe that plants in a greenhouse grow faster when exposed to red light compared to blue light. What is the next best step in your investigation?

Correct answer: D

Rationale: The next best step in the investigation would be to grow plants exposed to both red and blue light at equal intensities. This will help determine if the observed growth difference is due to the specific wavelength of light (red vs. blue) or if it is related to the intensity of light. By exposing plants to both red and blue light at equal intensities, you can compare their growth rates and determine if one wavelength has a greater effect on plant growth.

3. What is the largest muscle in the human body?

Correct answer: A

Rationale: The gluteus maximus is the largest muscle in the human body, located at the back of the hip and extending from the sacrum to the femur. It is a powerful muscle that plays a crucial role in extending the hip joint, enabling walking, running, and climbing stairs.

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. What part of speech is the underlined word in the sentence: "He felt a growing sense of unease"?

Correct answer: B

Rationale: "Sense" represents a concept or feeling, making it a noun here.

6. What part of speech is the underlined word in the sentence "I was disappointed by the outcome"?

Correct answer: C

Rationale: "Disappointed" modifies the pronoun "I," making it an adjective.
