1. Which of the following is the body cavity that contains the urinary bladder, urethra, and ureters?

Correct answer: B

Rationale: The correct answer is B, the pelvic cavity. The pelvic cavity houses organs related to the urinary and reproductive systems. The urinary bladder, urethra, and ureters are located in the pelvic cavity, making it the correct choice. The thoracic cavity contains the heart and lungs, while the abdominal cavity houses organs like the stomach and intestines. The spinal cavity, on the other hand, protects the spinal cord. Therefore, options A, C, and D are incorrect as they do not house the specific organs mentioned in the question.

2. Which bone is the longest in the human body?

Correct answer: A

Rationale: The correct answer is the femur (thigh bone) as it is the longest bone in the human body, extending from the hip to the knee. It plays a vital role in supporting the body's weight and enabling movement. The humerus is located in the upper arm and is not as long as the femur. The tibia is the shin bone and is shorter than the femur. The scapula is the shoulder blade and is not the longest bone in the body, making it an incorrect choice.

3. Sebaceous glands, located in the dermis, secrete an oily substance called:

Correct answer: B

Rationale: Sebaceous glands are responsible for secreting an oily substance called sebum, not sweat, cerumen, or mucus. Sebum plays a vital role in lubricating and waterproofing the skin and hair, preventing them from drying out. Sweat glands produce sweat to regulate body temperature. Cerumen is the medical term for earwax, produced by ceruminous glands in the ear canal, while mucus is a slimy substance that protects and lubricates body tissues. Therefore, the correct answer is B: Sebum, as it is the oily substance secreted by sebaceous glands.

4. Which type of nutrient requires the most complex and lengthy digestion process?

Correct answer: B

Rationale: Proteins require the most complex and lengthy digestion process compared to the other nutrient types provided. When proteins are consumed, they undergo a process where they need to be broken down into amino acids, which are essential building blocks of proteins. This intricate digestion process begins in the stomach aided by stomach acid and enzymes, proceeds to the small intestine where further enzymes break down proteins into amino acids, and concludes with the absorption of these amino acids into the bloodstream for various bodily functions. Carbohydrates and fats also require digestion, but the process for breaking down proteins into amino acids is notably more intricate and time-consuming. In contrast, vitamins do not require digestion in the same manner as proteins, carbohydrates, and fats because they are already in a form that can be readily absorbed by the body.

5. Identify the element with the electron configuration: 1s2 2s2 2p6 3s2 3p6. To which group and period does this element belong?

Correct answer: C

Rationale: The given electron configuration matches that of Argon, an element found in Group 18 of the periodic table. This element is in the third period, as indicated by the highest energy level (n=3) where electrons are present. Therefore, the correct answer is Group 18, Period 3. Choice A (Group 16, Period 3) corresponds to sulfur, not the given electron configuration. Choice B (Group 14, Period 3) corresponds to silicon, not the given electron configuration. Choice D (Group 17, Period 2) corresponds to chlorine, which is in Period 3 but not in Group 18, making it incorrect for the given electron configuration.
