Practice TEAS Test Reading

1. Which of the following statements offers a supporting argument for the passage's claim that many coastal islands are eroding?

Correct answer: C

Rationale: Statement C directly provides evidence of coastal land erosion by stating that Louisiana has lost a significant amount of coastal land area. This supports the passage's claim that many coastal islands are eroding. Choice A is incorrect because the expense of recent hurricane seasons does not directly relate to coastal land erosion. Choice B is incorrect as the active period of the Atlantic Basin does not specifically address coastal land erosion. Choice D, while related to coastal storms, does not directly support the claim that many coastal islands are eroding.

2. Which of the following vessels is responsible for pumping oxygenated blood to the body?

Correct answer: D

Rationale: The aorta is the correct answer because it is responsible for pumping oxygenated blood from the heart to the rest of the body. The aorta is the main artery that carries blood away from the heart and distributes it to all parts of the body, providing oxygen and nutrients to the tissues. Choices A, B, and C are incorrect. The right ventricle pumps deoxygenated blood to the lungs through the pulmonary artery, the left ventricle pumps oxygenated blood to the body through the aorta, and the pulmonary artery carries deoxygenated blood from the heart to the lungs for oxygenation.

3. Which is the correct order of formed elements in blood from smallest to largest cell size?

Correct answer: C

Rationale: The correct order of formed elements in blood from smallest to largest cell size is thrombocytes (platelets), erythrocytes (red blood cells), and leukocytes (white blood cells), making choice C the correct answer. Thrombocytes are the smallest, followed by erythrocytes, and then leukocytes. Choices A, B, and D are incorrect because they do not follow the correct order of cell size in blood formed elements.

4. What type of bond is formed when electrons are transferred between atoms?

Correct answer: D

Rationale: The correct answer is 'D: Ionic bond.' An ionic bond is formed when electrons are transferred between atoms. In an ionic bond, one atom donates electrons to another atom, resulting in the formation of positively and negatively charged ions that are attracted to each other, creating a strong bond. Choice A, 'Transfer bond,' is incorrect because there is no common term known as a 'Transfer bond' in chemistry. Choice B, 'Static bond,' is incorrect as it does not describe the process of electron transfer between atoms. Choice C, 'Covalent bond,' is incorrect because in a covalent bond, electrons are shared between atoms rather than transferred outright, making it different from an ionic bond.

5. The Minimum Inhibitory Concentration (MIC) of an antibiotic refers to:

Correct answer: B

Rationale: A) The lowest concentration that kills bacteria is known as the Minimum Bactericidal Concentration (MBC), not the Minimum Inhibitory Concentration (MIC). MIC is the lowest concentration of an antibiotic that inhibits visible growth of bacteria. B) The MIC of an antibiotic is the concentration at which bacterial growth is inhibited by 50%. This concentration is used to determine the effectiveness of an antibiotic against a specific bacterium. C) The time it takes for an antibiotic to work is not described by the MIC. MIC is a measure of concentration, not time. D) The spectrum of bacteria the antibiotic targets is not defined by the MIC. The MIC value is specific to a particular antibiotic and bacterium, regardless of the spectrum of activity of the antibiotic.
