TEAS 7 science quizlet Questions

Question 1 of 5

Through what tubes does urine travel from the kidneys to the bladder?

Correct Answer: B

Rationale: The correct answer is 'Ureters.' The ureters are the tubes that transport urine from the kidneys to the bladder. The urethra, not a choice in this question, is the tube responsible for carrying urine from the bladder out of the body. Renal arteries and veins are blood vessels that respectively supply and drain the kidneys, not involved in the transport of urine to the bladder.

Question 2 of 5

Which molecule is responsible for storing and providing a quick source of energy during short bursts of intense physical activity, such as weightlifting or sprinting?

Correct Answer: A

Rationale: ATP (Adenosine Triphosphate) is the molecule responsible for storing and providing a quick source of energy during short bursts of intense physical activity like weightlifting or sprinting. ATP is broken down to release energy rapidly when muscles need quick, intense efforts. Glucose is a source of energy but must be converted into ATP before it can be used by muscles. Myoglobin is a protein that stores oxygen in muscle cells and does not directly provide energy. Lactic acid is produced during intense exercise but is not the primary molecule responsible for providing quick energy during short bursts of intense physical activities.

Question 3 of 5

What is the difference between exhalation (expiration) and inhalation (inspiration)?

Correct Answer: A

Rationale: Exhalation (expiration) involves active muscle contraction, specifically the diaphragm and intercostal muscles, to decrease the volume of the thoracic cavity and push air out of the lungs. In contrast, inhalation (inspiration) is a passive process where the diaphragm and external intercostal muscles contract to increase the thoracic cavity volume, allowing air to flow into the lungs. Choice B is incorrect as exhalation removes carbon dioxide-rich air and inhalation brings in oxygen-rich air. Choice C is incorrect because both exhalation and inhalation can occur through the nose or mouth. Choice D is inaccurate as inhalation humidifies and warms the air, while exhalation cools and dries it.

Question 4 of 5

Muscle tissue is responsible for movement. Which type of muscle tissue is found in the heart?

Correct Answer: C

Rationale: Cardiac muscle is the type of muscle tissue found in the heart. Unlike skeletal muscle and smooth muscle, cardiac muscle is striated and involuntary, meaning it contracts without conscious control. It forms the majority of the heart's structure and is essential for its rhythmic contraction to pump blood throughout the body. Skeletal muscle is attached to bones and responsible for voluntary movements, while smooth muscle is found in organs and blood vessels, controlling various involuntary functions like digestion and blood flow. Therefore, choices A (Skeletal muscle) and B (Smooth muscle) are incorrect as they are not the types of muscle tissue found in the heart.

Question 5 of 5

In physics, what does the term 'net force' refer to?

Correct Answer: A

Rationale: In physics, the term 'net force' refers to the total force acting on an object, considering all individual forces acting on it. It is crucial in determining the object's motion and acceleration as it represents the overall force applied to the object. Choice B, 'Force due to gravity,' is incorrect as it refers to a specific force acting on an object due to gravity. Choice C, 'Force in motion,' is incorrect as it does not define the concept of net force. Choice D, 'Force of friction,' is incorrect as it specifically refers to the force opposing motion when two surfaces are in contact.
