2. What characteristic unites all organisms in the kingdom Animalia?

• A. Multicellularity and heterotrophy
• B. Unicellular nature
• C. Photosynthesis
• D. Cell walls made of chitin

Correct answer: A

Rationale: Rationale: A) Multicellularity and heterotrophy: This is the correct answer because all organisms in the kingdom Animalia are multicellular (composed of multiple cells) and exhibit heterotrophy (obtain nutrients by consuming other organisms). B) Unicellular nature: This is incorrect because organisms in the kingdom Animalia are multicellular, not unicellular. C) Photosynthesis: This is incorrect because organisms in the kingdom Animalia do not perform photosynthesis; they are heterotrophs that obtain nutrients by consuming other organisms. D) Cell walls made of chitin: This is incorrect because organisms in the kingdom Animalia do not have cell walls made of chitin. Chitin is a structural polysaccharide found in the cell walls of fungi, not animals.

3. What is the name of the master gland that regulates the function of many other endocrine glands?

• A. Thyroid gland
• B. Pituitary gland
• C. Hypothalamus
• D. Adrenal gland

Correct answer: B

Rationale: The correct answer is B: Pituitary gland. The pituitary gland is often referred to as the 'master gland' because it plays a crucial role in regulating the function of many other endocrine glands in the body. It secretes hormones that control various processes such as growth, metabolism, and reproduction. The thyroid gland (A) primarily regulates metabolism, the hypothalamus (C) helps control the pituitary gland, and the adrenal gland (D) produces hormones involved in stress response. Therefore, the pituitary gland is the main gland responsible for coordinating the activities of other endocrine glands, earning it the title of the master gland.

4. Antidiuretic hormone (ADH) plays a crucial role in regulating water balance. When ADH levels are high, what happens to urine production?

• A. Urine production increases significantly
• B. Urine production decreases to conserve water
• C. There is no change in urine production
• D. The kidneys stop producing urine altogether

Correct answer: B

Rationale: When antidiuretic hormone (ADH) levels are high, it indicates that the body needs to conserve water. ADH works by increasing the permeability of the collecting ducts in the kidneys, allowing more water to be reabsorbed back into the bloodstream. This action leads to a decrease in urine production, as the body retains more water to maintain proper fluid balance. Therefore, the correct answer is B: 'Urine production decreases to conserve water.' High levels of ADH help the body prevent dehydration by reducing the amount of water lost in urine.

5. Which pronoun correctly replaces the underlined phrase in the sentence: "Jessica invited Sarah and me to the party, but I forgot to respond to her."

6. Which property of a wave remains constant when the wave enters a different medium?
