TEAS Test 7 science quizlet Questions

Question 1 of 5

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.

Question 2 of 5

Which of the following is NOT an example of an intermolecular force?

Correct Answer: C

Rationale: Ionic bonding is not considered an intermolecular force but an intramolecular force. Intermolecular forces occur between different molecules, while intramolecular forces act within a molecule. Hydrogen bonding, dipole-dipole interactions, and London dispersion forces are intermolecular forces. Hydrogen bonding involves a hydrogen atom bonded to a highly electronegative atom, dipole-dipole interactions occur between polar molecules, and London dispersion forces are temporary attractions between nonpolar molecules.

Question 3 of 5

Which of the following nutrients is essential for muscle growth and repair?

Correct Answer: B

Rationale: Protein is essential for muscle growth and repair as it provides the necessary building blocks (amino acids) for muscle tissue synthesis and repair. While vitamins and minerals are crucial for overall health, protein has a specific role in muscle development. Carbohydrates supply energy for workouts, and fats are important for general health but are less directly involved in muscle growth and repair compared to protein.

Question 4 of 5

In the K-capture process, a type of electron capture, from which electron shell does the electron get captured?

Correct Answer: B

Rationale: The K-capture process involves the capture of an electron from the innermost electron shell, known as the K-shell. The K-shell comprises s and p orbitals. During the K-capture process, an electron is specifically captured from an inner p-orbital within the K-shell. Choices A, C, and D are incorrect because K-capture involves capturing an electron from the innermost shell (K-shell) which consists of s and p orbitals, not the outermost s-orbital, inner d-orbital, or any available electron shell.

Question 5 of 5

In the reaction 2H2 + O2 → 2H2O, how many moles of oxygen are required to react completely with 4 moles of hydrogen?

Correct Answer: B

Rationale: The balanced chemical equation indicates that 2 moles of H2 react with 1 mole of O2 to produce 2 moles of H2O. To determine how many moles of O2 are required to react with 4 moles of H2, you can use the mole ratio from the balanced equation: 2 moles of H2 react with 1 mole of O2. Therefore, to react completely with 4 moles of H2, you would need 2 moles of O2 (4 moles H2 � 2 moles H2 per 1 mole O2). Hence, 2 moles of oxygen are required to react completely with 4 moles of hydrogen. Choices A, C, and D are incorrect because they do not reflect the correct stoichiometry as defined by the balanced chemical equation.
