TEAS 7 science practice questions

1. What term describes the maximum displacement of particles from their rest position in a wave?

Correct answer: C

Rationale: The term that describes the maximum displacement of particles from their rest position in a wave is called the amplitude. Amplitude is a measure of the strength or intensity of a wave and is represented by the height of the wave from the rest position to the crest (or trough) of the wave. Frequency (A) refers to the number of complete wavelengths that pass a point in a given time. Wavelength (B) is the distance between two consecutive crests (or troughs) of a wave. Velocity (D) is the speed of the wave, not the maximum displacement of particles from their rest position.

2. Identify the organ responsible for blood filtration.

Correct answer: B

Rationale: The correct answer is B: Kidneys. The kidneys are the organs responsible for blood filtration in the human body. They filter waste products and excess substances from the blood to produce urine. The liver is primarily involved in detoxification and metabolism, the spleen functions in immune responses and blood storage, and the pancreas aids in digestion and blood sugar regulation. Therefore, choices A, C, and D are incorrect as they do not primarily serve the function of blood filtration.

3. Which of the following is the MOST common symptom of angina pectoris, a condition related to insufficient blood flow to the heart?

Correct answer: B

Rationale: Chest pain or discomfort is the most common symptom of angina pectoris. This pain is often described as squeezing, pressure, heaviness, tightness, or pain in the chest. Fever and chills, sudden onset of severe shortness of breath, and numbness or tingling in the extremities are not typical symptoms of angina pectoris. The pain associated with angina is usually triggered by physical or emotional stress and typically subsides with rest or medication, distinguishing it from other conditions.

4. What is the structure that connects the ovary to the uterus in the female reproductive system?

Correct answer: B

Rationale: The fallopian tubes are the structures that connect the ovaries to the uterus in the female reproductive system. These tubes serve as a pathway for the egg to travel from the ovary to the uterus, where fertilization typically occurs. Options (A) Urethra, (C) Vagina, and (D) Cervix are not the structures responsible for connecting the ovary to the uterus, making them incorrect choices for this question.

5. Which organ is responsible for filtering waste from the blood?

Correct answer: A

Rationale: The correct answer is A: Kidneys. The kidneys are responsible for filtering waste products from the blood, maintaining fluid and electrolyte balance. The pancreas aids in digestion and regulates blood sugar levels. The liver processes nutrients, detoxifies chemicals, and produces bile. The heart is responsible for pumping blood throughout the body. Choice B, Pancreas, is incorrect because the pancreas plays a role in digestion and blood sugar regulation, not in filtering waste from the blood. Choice C, Liver, is incorrect as the liver processes nutrients, detoxifies chemicals, and produces bile, but it is not primarily responsible for filtering waste from the blood. Choice D, Heart, is incorrect as the heart's main function is pumping blood throughout the body, not filtering waste from the blood.
