TEAS Test 7 science quizlet

1. What is the tough, fibrous connective tissue that attaches muscle to bone?

Correct answer: C

Rationale: Tendons are the correct answer as they are the tough, fibrous connective tissues that attach muscle to bone. They play a crucial role in transmitting the forces generated by muscle contraction to the bones, facilitating movement. Fascia surrounds muscles and provides support, perimysium is the connective tissue sheath around muscle fibers, and ligaments connect bone to bone, stabilizing joints, which makes them distinct from tendons.

2. A population refers to a group of organisms of the same:

Correct answer: A

Rationale: A population is defined as a group of organisms of the same species living in the same area and interacting with one another. Option A correctly describes this definition by specifying that the organisms are of the same species and share a common geographical location. Options B, C, and D are incorrect because they do not accurately define a population in biological terms. In this context, a population specifically refers to a group of organisms belonging to the same species, not higher taxonomic ranks like genus, kingdom, or phylum.

3. Which property of matter refers to the amount of space occupied by an object?

Correct answer: B

Rationale: Volume refers to the amount of space occupied by an object. It is a measure of the three-dimensional space that an object occupies. Mass, on the other hand, refers to the amount of matter in an object, weight is the force of gravity acting on an object, and density is the mass of an object per unit volume. In this context, volume is the most appropriate choice as it directly relates to the amount of space an object occupies.

4. How many moles of water are produced when 0.5 moles of methane (CH4) react with excess oxygen?

Correct answer: B

Rationale: The balanced chemical equation for the combustion of methane is: CH4 + 2O2 -> CO2 + 2H2O. This equation shows that 1 mole of methane produces 2 moles of water. Therefore, when 0.5 moles of methane react, they will produce 1 mole of water. The ratio of water to methane is 2:1, meaning that for every mole of methane that reacts, it produces 2 moles of water. Since only 0.5 moles of methane are reacting, the amount of water produced will be half of what would be produced if 1 mole of methane reacted, resulting in 1 mole of water being produced. Choice A is incorrect because it does not consider the stoichiometry of the reaction. Choices C and D are incorrect as they do not align with the balanced chemical equation and the stoichiometric ratios involved in the reaction.

5. What are the four chambers of the heart?

Correct answer: A

Rationale: The correct answer is A: Right atrium, left atrium, right ventricle, left ventricle. The heart consists of four chambers: the right atrium, left atrium, right ventricle, and left ventricle. Blood flows from the body into the right atrium, then to the right ventricle, where it is pumped to the lungs for oxygenation. Oxygenated blood returns to the left atrium, passes to the left ventricle, and is then pumped out to the body. Choice B is incorrect because it incorrectly lists the left atrium twice. Choice C is incorrect as it rearranges the order of the chambers. Choice D is incorrect as it mistakenly switches the atria and ventricles in their positions.
