TEAS Math Practice Test
1. What number is 6 equal to 30% of?
- A. 18
- B. 20
- C. 24
- D. 26
Correct answer: A
Rationale: To find the number that is 30% of 6, you can set up the equation 0.3x = 6. Solving for x gives x = 6 / 0.3 = 20. Therefore, 6 is equal to 30% of 20. Choice B, 20, is incorrect as it is the result of the calculation. Choice C, 24, and Choice D, 26, are incorrect as they are not the numbers that 6 is equal to 30% of.
2. Which hormone is produced by the thyroid gland?
- A. Insulin
- B. Thyroxine
- C. Adrenaline
- D. Cortisol
Correct answer: B
Rationale: The correct answer is B: Thyroxine. The thyroid gland produces thyroxine, a hormone essential for regulating metabolism. Insulin is produced by the pancreas to regulate blood sugar levels. Adrenaline is produced by the adrenal glands to prepare the body for the 'fight or flight' response. Cortisol is produced by the adrenal cortex in response to stress, not by the thyroid gland.
3. Which word choice best fits the blank: 'Her research paper was riddled with _____ errors.'
- A. flagrant (obvious and inexcusable)
- B. cursory (superficial)
- C. innocuous (harmless)
- D. meticulous (carefully detailed)
Correct answer: A
Rationale: The word 'flagrant' in option A is the most appropriate choice for the blank because it conveys the idea of errors that are glaringly obvious and inexcusable. In this context, the research paper is described as being 'riddled with errors,' suggesting a significant amount of mistakes that stand out and are severe. Choice B, 'cursory,' meaning superficial, does not accurately describe the seriousness of the errors. Choice C, 'innocuous,' meaning harmless, is the opposite of what is implied by the sentence. Choice D, 'meticulous,' meaning carefully detailed, is the opposite of what is needed to describe errors in this context.
4. What is the end product of glycolysis?
- A. Lactic acid
- B. ATP
- C. NADPH
- D. Pyruvic acid
Correct answer: D
Rationale: The correct answer is D: Pyruvic acid. The end product of glycolysis is pyruvic acid, not lactic acid, ATP, or NADPH. Pyruvic acid is a key intermediary in cellular respiration and can be further metabolized to produce energy through processes like the citric acid cycle and oxidative phosphorylation. Lactic acid is produced in the absence of oxygen during fermentation, ATP is a product of cellular respiration but not the direct end product of glycolysis, and NADPH is generated in other metabolic pathways such as the pentose phosphate pathway, not in glycolysis.
5. Which statement below best describes the process of condensation?
- A. Condensation is the process of changing from a gas to a liquid.
- B. Condensation is the process of changing from a liquid to a gas.
- C. Condensation is the process of changing from a solid to a liquid.
- D. Condensation is the process of changing from a solid to a gas.
Correct answer: A
Rationale: The correct answer is A: 'Condensation is the process of changing from a gas to a liquid.' Condensation occurs when a gas cools and transforms into a liquid state. For example, when water vapor in the air cools and forms droplets, it is an example of condensation. This process is commonly observed in the formation of clouds or dew on grass in the early morning. Choice B is incorrect because it describes the process of vaporization rather than condensation. Choice C is incorrect as it refers to the process of melting. Choice D is incorrect as it describes sublimation, which is the transition from a solid to a gas without passing through the liquid phase.
