TEAS Test 7 science quizlet

1. What is the main difference between white and brown adipose tissue?

Correct answer: B

Rationale: The main difference between white and brown adipose tissue lies in their function and energy metabolism. White adipose tissue is primarily involved in energy storage, while brown adipose tissue is specialized for energy expenditure and thermogenesis. This functional disparity is the key dissimilarity between white and brown adipose tissue, rather than just their location or color. Choice A is incorrect because the difference is not only in location but also in function. Choice C is incorrect as color is not the defining factor in their distinction. Choice D is incorrect as white and brown adipose tissues serve different functions in the body.

2. Which muscle is voluntary, striated, and found attached to bones?

Correct answer: B

Rationale: The correct answer is B, Skeletal muscle. Skeletal muscle is both voluntary and striated, as well as attached to bones, allowing for movement. Smooth muscle, on the other hand, is involuntary and typically found in the walls of internal organs, controlling functions like digestion. Cardiac muscle is also striated, but it is involuntary and specifically found in the heart, responsible for cardiac contractions to pump blood. 'Epithelial muscle' is an incorrect term; epithelial tissue is a type of tissue that forms the linings of various body surfaces and structures, not a muscle type.

3. 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.

4. What is the central idea of this passage?

Correct answer: C

Rationale: The central idea of the passage is to highlight the significance of understanding insects in ecosystems, not just focusing on their adaptability or life transitions. Choice A is incorrect as the passage does not introduce specific insects transitioning from water to air. Choice B is incorrect as the main focus is not solely on how insects adapt to their environment, but on their broader role in ecosystems. Choice D is incorrect as the passage does not discuss the duality of insect life, but rather their importance in the ecosystem.

5. How many milliliters are in a tablespoon?

Correct answer: B

Rationale: The correct answer is B: 15 ml. One tablespoon is equivalent to 15 milliliters. The conversion factor for tablespoons to milliliters is 1 tablespoon = 15 milliliters. Choice A (10 ml) is incorrect because it is not the standard conversion for a tablespoon. Choice C (5 ml) is incorrect as it is too low for a tablespoon. Choice D (20 ml) is incorrect as it is too high for a tablespoon. Therefore, the correct conversion is 15 milliliters for one tablespoon.
