1. Which part of the brain is responsible for regulating body temperature, hunger, and thirst, and is considered a key player in the endocrine system?

• A. Amygdala
• B. Hippocampus
• C. Hypothalamus
• D. Thalamus

Correct answer: c

Rationale: The correct answer is C: Hypothalamus. The hypothalamus is a small region in the brain that plays a crucial role in maintaining homeostasis by regulating body temperature, hunger, and thirst. It also serves as a key player in the endocrine system by controlling the release of hormones from the pituitary gland. The amygdala is responsible for processing emotions and memory, the hippocampus is involved in memory formation and retrieval, and the thalamus acts as a relay station for sensory information. Therefore, the hypothalamus is the most appropriate choice for the functions described in the question.

2. Identify the reflexive pronoun in the sentence: "She prepared herself for the presentation."

3. Which of the following is the main organ responsible for regulating sleep?

• A. Thalamus
• B. Hypothalamus
• C. Pituitary gland
• D. Pineal gland

Correct answer: B

Rationale: Rationale: The hypothalamus is the main organ responsible for regulating sleep. It plays a crucial role in controlling the body's circadian rhythm, which is the internal clock that regulates the sleep-wake cycle. The hypothalamus receives input from the eyes about light and darkness, which helps in determining when it is time to sleep or wake up. It also regulates the production of melatonin by the pineal gland, which is a hormone that helps control sleep patterns. While the thalamus is involved in relaying sensory information to the brain, the pituitary gland is responsible for producing and releasing hormones, and the pineal gland produces melatonin under the control of the hypothalamus.
