Practice Science TEAS Test
1. Which of the following joints is an example of a hinge joint?
- A. Hip joint
- B. Elbow joint
- C. Shoulder joint
- D. Knee joint
Correct answer: B
Rationale: The correct answer is B: Elbow joint. A hinge joint allows movement primarily in one plane, enabling bending and straightening actions. The elbow joint specifically functions as a hinge joint, facilitating the bending and straightening of the arm. The other options, such as the hip joint (A), shoulder joint (C), and knee joint (D), are not examples of hinge joints as they allow movement in multiple planes with more complex motions.
2. Which of the following is NOT a function of the endoplasmic reticulum (ER)?
- A. Synthesis of lipids (fats)
- B. Transport of materials within the cell
- C. Detoxification of harmful substances
- D. Breakdown of cellular waste products
Correct answer: D
Rationale: The endoplasmic reticulum (ER) is not involved in the breakdown of cellular waste products; this function is primarily carried out by lysosomes. The ER is responsible for the synthesis of lipids (fats), transport of materials within the cell, and detoxification of harmful substances. Lysosomes are the organelles responsible for breaking down cellular waste products through processes like autophagy. Therefore, option D is the correct answer as it does not align with the known functions of the endoplasmic reticulum.
3. Which of the following is the plural form of the word 'chief'?
- A. chiefs
- B. chieves
- C. chievs
- D. chiefes
Correct answer: A
Rationale: The correct answer is 'chiefs.' 'Chief' follows the standard rule for forming the plural by adding an 's' at the end. Choices B, C, and D are incorrect as they do not follow the standard pluralization rule for the word 'chief.' 'Chieves,' 'chievs,' and 'chiefes' are not valid plural forms of 'chief.'
4. What do large intestines absorb?
- A. Water, sodium, and potassium ions
- B. Proteins and carbohydrates
- C. Water, vitamin K, and bile salts
- D. Vitamins A, D, E, K
Correct answer: C
Rationale: The correct answer is C. The large intestine absorbs water, vitamin K, bile salts, sodium, and chloride ions. It helps in maintaining the body's water and electrolyte balance, and also plays a role in absorbing certain vitamins and nutrients such as vitamin K. Choices A, B, and D are incorrect because proteins, carbohydrates, vitamins A, D, E, and K are primarily absorbed in the small intestine, not the large intestine.
5. In a fraction, which number is the numerator and which is the denominator?
- A. Numerator: top, Denominator: bottom
- B. Numerator: bottom, Denominator: top
- C. Numerator: left, Denominator: right
- D. Numerator: right, Denominator: left
Correct answer: A
Rationale: The correct answer is A: 'Numerator: top, Denominator: bottom.' In a fraction, the numerator is the top number, representing the part of the whole being considered, while the denominator is the bottom number, indicating the total number of equal parts into which the whole is divided. Choices B, C, and D are incorrect because they provide inaccurate descriptions of the numerator and denominator positions in a fraction.
