1. A surgeon who is adroit might be described as ______.

• A. Careless
• B. Skillful
• C. Inexperienced
• D. Lazy

Correct answer: B

Rationale: The word 'adroit' means skillful or proficient. A surgeon who is adroit would be highly skilled and proficient in their work. Therefore, the most appropriate description for a surgeon who is adroit is 'skillful.' Choices A, C, and D are incorrect because they do not reflect the positive attribute associated with being adroit.

2. What is a primary function of the skeletal system?

• A. Production of red blood cells
• B. Support and protection
• C. Secretion of hormones
• D. Regulation of body temperature

Correct answer: B

Rationale: The correct answer is B: Support and protection. The primary functions of the skeletal system include providing structural support to the body and protecting internal organs. While the skeletal system also plays a role in hematopoiesis (production of blood cells) and stores minerals, its main function is to support the body's framework and protect vital organs. Choices A, C, and D are incorrect as they do not directly relate to the primary functions of the skeletal system.

3. What is the energy required to remove the outermost electron from an atom called?

• A. covalent bonding
• B. electronegativity
• C. atomic radius
• D. ionization energy

Correct answer: D

Rationale: Ionization energy is the energy needed to remove the outermost electron from an atom, resulting in the formation of a positively charged ion. The higher the ionization energy, the more difficult it is to extract an electron. Electronegativity, however, measures an atom's ability to attract shared electrons in a chemical bond. Atomic radius refers to the distance from the nucleus to the outermost electron. Covalent bonding involves sharing electron pairs between atoms to create a stable bond. Therefore, the correct answer is ionization energy as it specifically relates to the energy needed to remove an electron from an atom.

4. What is the overall tone of the essay?

• A. Apathetic
• B. Fascinated
• C. Discouraged
• D. Hopeful

Correct answer: C

Rationale: The overall tone of the essay is discouraged, as it conveys concern over the United States’ lower ranking in life expectancy and highlights various health issues contributing to this situation. The language used suggests frustration and disappointment regarding the country's health statistics, supporting option C as the correct answer.

5. What type of cells are involved in meiosis (sex cells)?

• A. Somatic Cells
• B. Gametes
• C. Zygote
• D. Diploid Cells

Correct answer: B

Rationale: The correct answer is B, Gametes. Gametes are the specialized sex cells involved in meiosis, such as sperm and eggs. Somatic cells (A) are non-reproductive cells found in the body, not involved in meiosis. Zygote (C) is the result of fertilization, formed when gametes unite. Diploid cells (D) have two sets of chromosomes, but in meiosis, gametes are produced through a process of cell division that reduces the chromosome number by half to haploid.
