TEAS Test 7 science quizlet

1. Which blood vessels are responsible for carrying oxygenated blood away from the heart to the rest of the body?

Correct answer: B

Rationale: Arteries are the blood vessels responsible for carrying oxygenated blood away from the heart to the rest of the body. Their thick, muscular walls allow them to withstand high pressure and efficiently transport blood to various tissues and organs throughout the body. Veins (choice A) carry deoxygenated blood back to the heart, capillaries (choice C) facilitate the exchange of nutrients and waste products between the blood and tissues, and venules (choice D) are small blood vessels that collect blood from the capillaries and gradually converge into veins.

2. The van't Hoff factor (i) accounts for the number of particles a solute dissociates into in solution. For a compound that dissociates completely in water, i would be...

Correct answer: D

Rationale: The van't Hoff factor (i) represents the number of particles a solute dissociates into in solution. For a compound that dissociates completely in water, i would be more than 1 because it breaks apart into more particles than the original compound. This is due to complete dissociation leading to an increase in the number of particles in solution, resulting in i being greater than 1. Choice A is incorrect as a compound that dissociates completely will not have an i value of 0. Choice B is incorrect because when a compound dissociates completely, the van't Hoff factor is not less than 1. Choice C is incorrect as a compound that dissociates completely will not have an i value of 1, but rather more than 1 due to the increased number of particles in solution.

3. Which factor do colligative properties of solutions depend on?

Correct answer: D

Rationale: Colligative properties of solutions depend on the number of solute particles in solution. These properties, such as boiling point elevation, freezing point depression, vapor pressure lowering, and osmotic pressure, are proportional to the number of solute particles present in the solution. The chemical identity of the solute or the concentration of the solvent does not influence colligative properties, making choices A and C incorrect. Therefore, the correct answer is D, the number of solute particles in solution.

4. Teddy has been assigned to write a history paper about the United States during the Cold War. What choice of three classes would likely be the most useful?

Correct answer: C

Rationale: Based on the Dewey Decimal System, which is a library classification system, the subjects related to Chomsky's work, which touches on philosophy, social sciences, and history, fall under classes 100, 400, and 900. Therefore, these classes would be the most useful for Teddy's history paper about the United States during the Cold War. Choices A, B, and D are incorrect because they do not include the specific classes related to the required subjects for Teddy's paper.

5. Simplify the expression 3x - 5x + 2.

Correct answer: D

Rationale: When simplifying the expression 3x - 5x + 2, start by combining like terms. -5x is subtracted from 3x to give -2x. Adding 2 at the end gives the simplified expression -2x. Therefore, the correct answer is -2x. Choice A, -2x + 2, incorrectly adds 2 at the end. Choice B, -8x, incorrectly combines the coefficients of x without considering the constant term. Choice C, 2x + 2, incorrectly adds the coefficients of x without simplifying.
