1. What is the fluid-filled, jelly-like substance within the cell that suspends the organelles called?
- A. Nucleus
- B. Cytoplasm
- C. Plasma membrane
- D. Golgi apparatus
Correct answer: B
Rationale: The correct answer is B, cytoplasm. Cytoplasm is the fluid-filled, jelly-like substance within the cell that suspends the organelles. The nucleus, not the correct answer, is the organelle that contains the cell's genetic material. The plasma membrane, another incorrect choice, is the outer boundary of the cell that regulates what enters and exits the cell. The Golgi apparatus, also an incorrect choice, is an organelle involved in processing and packaging proteins.
2. This passage is most likely taken from a(n) _____.
- A. Self-help manual
- B. Autobiography
- C. Epistle
- D. Novel
Correct answer: A
Rationale: The passage reads like a self-help manual as it offers advice and guidance on managing money and achieving financial independence. It provides practical tips on making and keeping money, emphasizing the importance of living within one's means. The content is focused on providing instruction rather than personal experiences (autobiography), formal letters (epistle), or fictional storytelling (novel).
3. What is the sum of two odd numbers, two even numbers, and an odd number and an even number?
- A. Odd + Odd = Even; Even + Even = Even; Odd + Even = Odd
- B. Odd + Odd = Odd; Even + Even = Even; Odd + Even = Even
- C. Odd + Odd = Even; Even + Even = Odd; Odd + Even = Even
- D. Odd + Odd = Odd; Even + Even = Odd; Odd + Even = Even
Correct answer: A
Rationale: The sum of two odd numbers is even because odd numbers have a difference of 1 and adding them results in a multiple of 2. The sum of two even numbers is even because even numbers are multiples of 2. When an odd number and an even number are added, the result is odd because the even number contributes an extra 1 to the sum, making it an odd number. Therefore, the correct answer is A. Choices B, C, and D have incorrect combinations of the sum of odd and even numbers.
4. What is the technical term for the free edges of your fingernails and toenails?
- A. Lunula (The lunula is the white crescent moon shape at the base of the nail)
- B. Matrix (The matrix is the area under the nail where new nail cells are produced)
- C. Hyponychium (This is the skin under the free edge of the nail)
- D. Free edge
Correct answer: C
Rationale: The correct answer is C, hyponychium. The hyponychium is the skin under the free edge of the nail, responsible for sealing the nail to the fingertip and protecting the nail bed from bacteria and debris. The lunula (choice A) refers to the white crescent moon shape at the base of the nail. The matrix (choice B) is the area under the nail where new nail cells are produced. The free edge (choice D) is the part of the nail that extends beyond the fingertip or toe.
5. What is the volume of a ball with a diameter of 7 inches?
- A. 165.7 in³
- B. 179.6 in³
- C. 184.5 in³
- D. 192.3 in³
Correct answer: A
Rationale: To find the volume of a sphere, the formula V = (4/3)πr³ is used, where r is the radius of the sphere. Given that the diameter of the ball is 7 inches, the radius (r) would be half of the diameter, which is 3.5 inches. Plugging this value into the formula: V = (4/3)π(3.5)³ = (4/3)π(42.875) ≈ 165.7 in³. Therefore, the correct answer is A. Choice B, C, and D are incorrect as they do not accurately represent the volume of the ball with a diameter of 7 inches.
