TEAS Test 7 science quizlet

1. What is the term used to describe the inability of the kidneys to effectively filter waste products from the blood?

Correct answer: B

Rationale: Kidney failure is the term used to describe the inability of the kidneys to effectively filter waste products from the blood. Dehydration refers to insufficient fluid intake and not the kidney's filtering function. Incontinence is the loss of bladder control, not related to kidney filtration. Nephritis is the inflammation of the kidneys, not specifically related to the kidneys' inability to filter waste products.

2. Which protein complex in the sarcomere is responsible for the thick filament?

Correct answer: B

Rationale: Myosin is the protein complex responsible for the thick filament in the sarcomere. It interacts with actin, another protein in the sarcomere, to generate the sliding movement that results in muscle contraction. Actin is a thin filament protein that interacts with myosin to create the sliding filament mechanism. Tropomyosin and troponin are regulatory proteins that regulate muscle contraction by controlling the interaction between actin and myosin, rather than directly being responsible for the thick filament.

3. Which law of motion explains the behavior of rockets in space?

Correct answer: C

Rationale: The correct answer is Newton's Third Law. Newton's Third Law states that for every action, there is an equal and opposite reaction. In the case of rockets in space, the action is the expulsion of gas from the rocket engines, and the reaction is the forward motion of the rocket. This law explains how rockets are able to propel themselves forward in the vacuum of space. Choices A and B are incorrect because Newton's First Law (inertia) and Second Law (F=ma) do not directly explain the behavior of rockets in space. Choice D is incorrect as Newton's Third Law specifically addresses the principle behind rockets' motion in space.

4. Which structure of the respiratory system bifurcates into the primary bronchi?

Correct answer: A

Rationale: The trachea is the structure that bifurcates into the primary bronchi. The trachea is a tube that carries air to and from the lungs. It divides into the left and right primary bronchi at a specific point called the carina, which then further divide into secondary and tertiary bronchi, leading to the bronchioles. The alveoli are the tiny air sacs at the end of the bronchioles where gas exchange occurs, not the structure that bifurcates into the primary bronchi. Bronchioles are smaller airway branches that come after the bronchi but do not bifurcate into them. The larynx, also known as the voice box, is located above the trachea and is responsible for sound production, not the bifurcation into primary bronchi. Therefore, the correct answer is the trachea.

5. Which respiratory structure is responsible for vocalization and sound production?

Correct answer: B

Rationale: The correct answer is B: Larynx. The larynx, also known as the voice box, is the respiratory structure responsible for vocalization and sound production. It contains the vocal cords, which vibrate as air passes through, producing sound. The trachea (A) connects the larynx to the bronchi. While the trachea serves as the windpipe, it is not directly involved in sound production. Bronchi (C) are airway passages that branch off from the trachea and lead to the lungs, but they are not responsible for vocalization. Alveoli (D) are tiny air sacs in the lungs where gas exchange occurs, but they are not involved in sound production.
