Practice TEAS Science Test Questions
Question 1 of 5
Which method is most suitable for measuring the volume of a cube?
Correct Answer: B
Rationale: The correct answer is B: Measuring wheel and mathematical formula. To measure the volume of a cube, you need to measure the length of one side using a measuring wheel and then use the formula V = s^3, where V is the volume and s is the length of one side. This method is suitable because it directly measures the side length of the cube, which is essential for calculating the volume accurately. Choice A, the triple beam balance, is used for measuring mass, not volume. Choice C, the graduated cylinder, is used to measure the volume of irregularly shaped objects using water displacement method, not ideal for a cube. Choice D, the measuring wheel alone, does not provide the formula for calculating the volume of a cube, making it less suitable compared to choice B.
Question 2 of 5
Which structure in the skin is responsible for producing oil that keeps the skin and hair moisturized?
Correct Answer: B
Rationale: The correct answer is B: Sebaceous gland. Sebaceous glands produce sebum, an oily substance that helps moisturize the skin and hair. The sudoriferous gland produces sweat, not oil. The hair follicle anchors the hair to the skin, it does not produce oil. Melanocytes are responsible for producing melanin, the pigment that gives skin its color, not oil. Therefore, the sebaceous gland is the structure responsible for producing oil to keep the skin and hair moisturized.
Question 3 of 5
Which organ stores and concentrates bile?
Correct Answer: B
Rationale: The correct answer is B: Gallbladder. The gallbladder stores and concentrates bile produced by the liver, releasing it into the small intestine to aid in digestion. The liver produces bile but does not store it. The pancreas produces digestive enzymes, not bile. The stomach produces gastric juices for digestion, not bile.
Question 4 of 5
Which part of the cell is responsible for storing genetic information?
Correct Answer: C
Rationale: The correct answer is C: Nucleus. The nucleus contains the cell's genetic material in the form of DNA, which carries the instructions for the cell's functions and characteristics. This is where processes such as transcription and replication occur. Ribosomes (choice A) are responsible for protein synthesis. Mitochondria (choice B) are the powerhouse of the cell, producing energy. Cytoplasm (choice D) is the fluid that fills the cell and supports organelles, but it does not store genetic information.
