TEAS 7 science quizlet

1. Which types of waves are capable of interference and diffraction?

Correct answer: D

Rationale: Both longitudinal and transverse waves are capable of interference and diffraction. Interference occurs when two or more waves overlap and combine, either constructively (increasing amplitude) or destructively (decreasing amplitude). Diffraction is the bending of waves around obstacles or through openings, which can occur with both longitudinal and transverse waves. Choice A is incorrect because only stating longitudinal waves can undergo interference and diffraction is inaccurate. Choice B is also incorrect as transverse waves, not just longitudinal waves, can exhibit these phenomena. Choice C is incorrect because electromagnetic waves are a broad category that includes both longitudinal and transverse waves, so it is not exclusive to either type. The correct answer is D because both longitudinal and transverse waves can demonstrate interference and diffraction.

2. The lymphatic system is a network of vessels and organs that plays a vital role in:

Correct answer: B

Rationale: The correct answer is B: Carrying waste products away from tissues. The lymphatic system functions to maintain fluid balance in the body by removing excess fluid, filtering out harmful substances, and transporting waste products away from tissues. It does not primarily focus on transporting oxygen and nutrients to cells, regulating body temperature, or producing red blood cells. Choices A, C, and D are incorrect as the primary function of the lymphatic system is related to waste removal and maintaining fluid balance in the body, rather than roles such as nutrient transport, temperature regulation, or red blood cell production.

3. Which of the following types of muscle tissue is found attached to bones and allows for voluntary movement?

Correct answer: C

Rationale: The correct answer is C: Skeletal muscle. Skeletal muscle is attached to bones and allows for voluntary movement, such as walking, running, and lifting objects. Smooth muscle, found in the walls of internal organs and blood vessels, is responsible for involuntary movements. Cardiac muscle is specific to the heart and controls involuntary contraction. Connective tissue, on the other hand, provides support and connects different structures in the body, but it is not responsible for voluntary movement like skeletal muscle.

4. During which phase of the cardiac cycle do the atria contract, pushing blood into the ventricles?

Correct answer: C

Rationale: Atrial systole is the phase of the cardiac cycle during which the atria contract, pushing blood into the ventricles. This occurs after the atria have been filled during atrial diastole. Ventricular systole refers to the phase when the ventricles contract to push blood out of the heart, not when the atria contract. Ventricular diastole is the phase when the ventricles relax and fill with blood, not when the atria contract. Therefore, the correct answer is atrial systole as it specifically describes the atrial contraction phase.

5. What is the role of hemoglobin in red blood cells?

Correct answer: B

Rationale: Hemoglobin in red blood cells functions to carry oxygen from the lungs to tissues in the body. It binds to oxygen in the lungs and releases it to the body's cells, ensuring they have an adequate oxygen supply for metabolic processes. Choice A is incorrect because hemoglobin primarily carries oxygen, not carbon dioxide. Choice C is incorrect because hemoglobin's role is not related to blood pressure regulation. Choice D is incorrect because hemoglobin is not involved in the production of white blood cells.
