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?

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. Which type of energy is associated with the random motion of particles in a substance?

Correct answer: c

Rationale: Thermal energy is related to the random motion of particles in a substance and is associated with temperature.

3. The longest bone in the human body is the:

Correct answer: C

Rationale: The correct answer is C: "Femur." The femur is the longest bone in the human body, located in the thigh region and connecting the hip to the knee. It plays a crucial role in supporting the body's weight and facilitating movement. The tibia and fibula are bones in the lower leg, while the humerus is a bone in the upper arm. Therefore, the femur is the correct answer for the longest bone in the human body.

4. What is the function of the pituitary gland?

Correct answer: A

Rationale: The pituitary gland is often referred to as the "master gland" because it controls the activity of many other endocrine glands in the body. It is located at the base of the brain and produces a variety of hormones that regulate various bodily functions, including growth, metabolism, reproduction, and blood pressure.

5. 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.

6. Which hormone is responsible for stimulating the development of sex organs and secondary sex characteristics during puberty?

Correct answer: B

Rationale: The correct answer is B: Testosterone (in males) and Estrogen (in females). During puberty, the release of these sex hormones plays a crucial role in the development of sex organs and secondary sex characteristics. Testosterone is responsible for male characteristics like facial hair, deepening of the voice, and muscle growth, while Estrogen contributes to female features such as breast development and the widening of hips. Growth hormone primarily regulates overall growth and development, while Insulin is involved in glucose metabolism and Thyroid hormone controls metabolism and energy levels. Therefore, the correct choice is B as Testosterone and Estrogen are specifically responsible for the changes seen during puberty.
