Question 1: Define the cerebrum and explain its primary functions in the human brain.

Answer: The cerebrum is the largest part of the brain responsible for voluntary activities, sensory perception, reasoning, and problem-solving.

Question 2: Describe the role of the hypothalamus in maintaining homeostasis.

Answer: The hypothalamus regulates body temperature, hunger, thirst, sleep, and hormonal balance to maintain homeostasis.

Question 3: Which part of the brain is primarily responsible for coordination and balance?

Answer:

Question 4: Fill in the blank: The __________ is involved in processing sensory information and is located at the top of the brain.

Answer: cerebrum

Question 5: List two functions of the brainstem.

Answer: Regulates vital functions such as heartbeat, breathing, and blood pressure.

Question 6: Calculate the average weight of a human brain in grams if the weights of five different brains are 1350 g, 1420 g, 1380 g, 1400 g, and 1360 g.

Answer: Average weight = (1350 + 1420 + 1380 + 1400 + 1360) / 5 = 1382 g

Question 7: Identify the variable: In an experiment measuring the effect of sleep deprivation on reaction time, what is the independent variable?

Answer: The amount of sleep deprivation (hours of sleep lost).

Question 8: Describe one safety precaution to consider when conducting a theoretical experiment on brain activity measurement.

Answer: Ensure that participants do not experience discomfort or harm, and obtain informed consent.

Question 9: A study reports that the hippocampus volume is reduced in patients with Alzheimer’s disease. What type of data analysis is this?

Answer:

Question 10: Explain how the brain's structure relates to its function in maintaining homeostasis.

Answer: Different parts of the brain are specialized for specific functions that help maintain homeostasis. For example, the hypothalamus detects changes in body temperature and initiates responses to restore balance, while the medulla oblongata controls vital functions like heartbeat and breathing. The structural organization allows efficient processing and regulation of physiological processes essential for stability.
