1. Which type of nuclear force is responsible for holding protons and neutrons together in the nucleus of an atom?
- A. Electromagnetism
- B. Gravity
- C. Strong nuclear force

2. The deeper layer of the skin, containing connective tissue, blood vessels, and nerve endings, is called the:
- A. Epidermis
- B. Dermis
- C. Hypodermis
- D. Stratum corneum
Correct answer: B
Rationale: The correct answer is B: Dermis. The dermis is the deeper layer of the skin that contains important structures such as connective tissue, blood vessels, and nerve endings. It plays a crucial role in providing support and nourishment to the epidermis, the outermost layer of the skin. The epidermis, option A, is actually the outermost layer responsible for protecting the body from environmental factors. The hypodermis, option C, is the deepest layer of the skin that primarily consists of fat and connective tissue. Stratum corneum, option D, is the outermost layer of the epidermis composed of dead skin cells. Therefore, the dermis is the correct answer in this case.
3. Which of the following numbers is NOT divisible by 3?
- A. 105
- B. 141
- C. 273
- D. 810
Correct answer: D
Rationale: Rationale: To determine if a number is divisible by 3, we can check if the sum of its digits is divisible by 3. If the sum of the digits is divisible by 3, then the original number is also divisible by 3. A) 105: 1 + 0 + 5 = 6, which is divisible by 3. Therefore, 105 is divisible by 3. B) 141: 1 + 4 + 1 = 6, which is divisible by 3. Therefore, 141 is divisible by 3. C) 273: 2 + 7 + 3 = 12, which is divisible by 3. Therefore, 273 is divisible by 3. D) 810: 8 + 1 + 0 = 9, which is divisible by 3. Therefore, 810 is divisible by 3. Since all the
