TEAS 7 science quizlet

1. 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.

2. A ball is thrown horizontally off a cliff. Which of the following forces is responsible for its downward motion?

Correct answer: D

Rationale: The gravitational force is responsible for the downward motion of the ball. When the ball is thrown horizontally off a cliff, the only force acting on it in the vertical direction is the force of gravity, which pulls the ball downward towards the ground. The other forces mentioned (force of throwing, normal force from the air, tension force from the string) do not contribute to the ball's downward motion in this scenario. The force of throwing initiates the horizontal motion, the normal force from the air opposes the ball's motion through air resistance, and tension force from the string would only be relevant if a string were attached to the ball. Therefore, gravitational force is the primary force responsible for the ball's downward motion in this situation.

3. Unlike the circulatory system, the lymphatic system does not have a pump. How does lymph move through the lymphatic vessels?

Correct answer: C

Rationale: Lymph moves through the lymphatic vessels primarily due to muscle contractions and breathing movements and also with the help of one-way valves within the vessels. The lymphatic system lacks a central pump like the heart; hence, it relies on the contraction of surrounding muscles and breathing movements to propel lymph fluid. One-way valves within the lymphatic vessels prevent backflow and ensure the unidirectional flow of lymph. Option A is incorrect as the lymphatic system does not rely on the pumping action of the heart. Option D is incorrect as the correct answer is the combination of muscle contractions, breathing movements, and one-way valves, not all the options provided.

4. Which of the following is considered an extensive property?

Correct answer: A

Rationale: Weight is correctly identified as an extensive property. Extensive properties are dependent on the amount of the substance present. Weight is directly proportional to the quantity of the substance, making it an extensive property. In contrast, density, conductivity, and malleability are intensive properties, which remain constant regardless of the amount of substance. Therefore, the correct answer is 'Weight' as it changes with the quantity of the substance, aligning with the definition of an extensive property.

5. Which type of muscle is under voluntary control?

Correct answer: C

Rationale: The correct answer is C: Skeletal muscle. Skeletal muscle is under voluntary control, allowing for conscious movement of the body. Smooth muscle and cardiac muscle are both types of involuntary muscles that are not under conscious control. Smooth muscle is found in the walls of internal organs and blood vessels, functioning involuntarily. Cardiac muscle makes up the heart and contracts involuntarily to pump blood. Involuntary muscle (choice D) is a general term that encompasses smooth muscle and cardiac muscle, which operate involuntarily throughout the body.
