1. What kind of bond links amino acids together?

• A. Hydrogen bond
• B. Ionic bond
• C. Disulfide bond
• D. Covalent bond

Correct answer: D

Rationale: Rationale: Amino acids are linked together by covalent bonds to form proteins. A covalent bond is a strong chemical bond formed by the sharing of electrons between atoms. In the case of amino acids, the covalent bond that links them together is called a peptide bond. This bond forms between the amino group of one amino acid and the carboxyl group of another amino acid, resulting in the formation of a peptide chain. Hydrogen bonds, ionic bonds, and disulfide bonds can also play roles in protein structure and stability, but the primary bond linking amino acids together in a protein chain is the covalent peptide bond.

2. What is the term for a group of organisms with the same genetic makeup?

• A. Population
• B. Clone
• C. Genotype
• D. Species

Correct answer: B

Rationale: Rationale: - A population (option A) refers to a group of individuals of the same species living in the same area. - Genotype (option C) refers to the genetic makeup of an individual organism. - Species (option D) refers to a group of organisms that can interbreed and produce fertile offspring. In this context, a clone (option B) is a group of organisms that are genetically identical because they are derived from a single ancestor. This term specifically refers to organisms with the same genetic makeup, making it the most appropriate choice for the question.

3. What is the best way to punctuate the dialogue "Are you coming?" she asked. "Maybe," I replied.

• A. "Are you coming?" she asked? "Maybe," I replied.
• B. "Are you coming?" she asked. "Maybe," I replied.
• C. "Are you coming?" she asked, "Maybe," I replied.
• D. "Are you coming?" she asked, "Maybe," I replied.

Correct answer: B

Rationale: Each speaker's words need quotation marks, and the question mark should go inside the closing quotation mark of the question.

4. Which of the following glands is NOT directly controlled by the pituitary gland?

• A. Thyroid gland
• B. Adrenal glands
• C. Pancreas (islets of Langerhans)
• D. Parathyroid glands

Correct answer: C

Rationale: The correct answer is C. The pituitary gland is often referred to as the 'master gland' because it secretes hormones that control the functions of other endocrine glands. The thyroid gland (A), adrenal glands (B), and parathyroid glands (D) are directly controlled by the pituitary gland through the release of specific hormones. However, the pancreas, specifically the islets of Langerhans (C), is not directly controlled by the pituitary gland. The pancreas is regulated by hormones such as insulin and glucagon, which are not secreted by the pituitary gland. Therefore, option C is the correct answer as it is not directly influenced by the pituitary gland's hormonal regulation.

5. How do isotopes affect the atomic mass of an element?

• A. Isotopes have no effect on the atomic mass of an element.
• B. Isotopes cause the atomic mass of an element to vary slightly.
• C. Isotopes cause the atomic mass of an element to be exactly the same for all isotopes of that element.
• D. Isotopes cause the atomic mass of an element to vary greatly.

Correct answer: B

Rationale: The atomic mass of an element is the average mass of all the isotopes of that element. Since isotopes have different numbers of neutrons, they also have slightly different masses. This variation in mass is what causes the atomic mass of an element to be a decimal number, rather than a whole number.

6. She reads about Path Goal theory. Which of the following behaviors is manifested by the

• A. Recognizes staff for going beyond expectations by giving them citations
• B. Challenges the staff to take individual accountability for their own practice
• C. Admonishes staff for being laggards.
• D. Reminds staff about the sanctions for non performance.

Correct answer: B

Rationale: The correct answer is B: 'Challenges the staff to take individual accountability for their own practice.' Path-Goal theory emphasizes the leader's role in motivating and guiding their team to achieve goals. This behavior aligns with the theory as it focuses on empowering employees to take ownership of their actions and responsibilities. By challenging staff to be individually accountable, the leader is providing clear direction and support, which can enhance motivation and performance within the team. Recognizing and rewarding staff for going beyond expectations (option A) would be more aligned with a transformational leadership style. Admonishing staff for being laggards (option C) and reminding staff about sanctions (option D) are not effective leadership behaviors according to the Path-Goal theory, as they do not focus on motivating and supporting employees to reach their goals.
