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. According to Newton's third law of motion, for every action, there is an equal and opposite _________.

Correct answer: A

Rationale: Newton's third law of motion states that for every action, there is an equal and opposite reaction. This law emphasizes that forces always exist in pairs. When one object exerts a force on a second object (action), the second object exerts an equal force in the opposite direction back on the first object (reaction). This principle is crucial in understanding the interactions between objects and the resulting motion observed in the physical world. Choices B, C, and D are incorrect because while force is involved, the specific concept highlighted by Newton's third law is the equal and opposite reaction. Acceleration and momentum are also related to motion but are not directly tied to Newton's third law of motion, which focuses on the equality and oppositeness of forces in interactions.

3. What is the pH of a solution with a hydrogen ion concentration of (1x10^{-9}) M?

Correct answer: C

Rationale: The pH of a solution can be calculated using the formula: pH = -log[H+]. Given that the hydrogen ion concentration is \(1 \times 10^{-9}\) M, the pH can be calculated as pH = -log(1 x 10^-9) = 9. Therefore, the correct answer is C) 9.

4. Which type of reaction undergoes hydrolysis?

Correct answer: B

Rationale: The correct answer is 'Catabolism.' Catabolic reactions involve the breakdown of larger molecules into smaller ones, often through hydrolysis, where water is added to break chemical bonds. This process is essential for the degradation of complex molecules and the release of energy stored in chemical bonds. Choice A, 'Anabolism,' is incorrect as anabolism involves the synthesis of complex molecules from simpler ones. Choices C and D, 'Exothermic' and 'Endothermic,' refer to the heat energy exchange during a reaction and are not directly related to the process of hydrolysis.

5. Which form of energy is associated with the motion of an object?

Correct answer: A

Rationale: Kinetic energy is the form of energy associated with the motion of an object. When an object is in motion, it possesses kinetic energy due to its movement. Potential energy, on the other hand, is stored energy that an object has due to its position or condition. Thermal energy is related to heat, while electrical energy is associated with the flow of electric charge. In this case, the correct answer is kinetic energy as it directly correlates with the motion of an object.
