1. What is the building block of RNA?

• A. Amino acid
• B. Nucleotide
• C. Protein
• D. Fatty acid

Correct answer: B

Rationale: Nucleotide: Nucleotides are the building blocks of RNA. A nucleotide consists of a nitrogenous base (adenine, guanine, cytosine, or uracil in RNA), a sugar (ribose in RNA), and a phosphate group. A) Amino acid: Amino acids are the building blocks of proteins, not RNA. C) Protein: Proteins are made up of amino acids, not nucleotides. D) Fatty acid: Fatty acids are components of lipids, not RNA.

2. Which of the following joints is an example of a hinge joint?

• A. Hip joint
• B. Elbow joint
• C. Shoulder joint
• D. Knee joint

Correct answer: B

Rationale: The correct answer is B: Elbow joint. A hinge joint allows movement primarily in one plane, enabling bending and straightening actions. The elbow joint specifically functions as a hinge joint, facilitating the bending and straightening of the arm. The other options, such as the hip joint (A), shoulder joint (C), and knee joint (D), are not examples of hinge joints as they allow movement in multiple planes with more complex motions.

3. Which of the following is true about calcium-rich foods? I. Canned salmon with bones contains calcium. II. Cheese is a lactose-free food. III. Condensed soup made with water is a calcium-rich food.

• A. I only
• B. I and II only
• C. II and III only
• D. III only

Correct answer: A

Rationale: The correct answer is 'I only.' Canned salmon with bones contains calcium as the bones are a good source of calcium, making statement I true. However, statement II is false as cheese is not a lactose-free food. Statement III is also incorrect as condensed soup made with water is not necessarily a calcium-rich food. Other calcium-rich options include dairy products like milk, yogurt, and specific non-dairy products like calcium-fortified juices, canned fish with bones, soybeans, and leafy greens.

4. What is the purpose of genetic counseling?

• A. To treat genetic disorders.
• B. To diagnose genetic diseases in newborns.
• C. To provide information and support to individuals and families with genetic risks.
• D. To collect DNA samples for research purposes.

Correct answer: C

Rationale: The purpose of genetic counseling is to provide information and support to individuals and families with genetic risks. Genetic counselors aim to explain the implications of genetic testing, discuss risks and options, and offer emotional and psychological support to help individuals make informed decisions regarding their genetic health. Choice A is incorrect because genetic counseling is not focused on treatment but rather on providing information and support. Choice B is incorrect as genetic counselors do not primarily diagnose genetic diseases in newborns but rather provide guidance and support based on existing diagnoses. Choice D is not the purpose of genetic counseling; genetic counselors do not collect DNA samples for research purposes but instead focus on assisting individuals and families in understanding and managing their genetic risks.

5. Which of the following best describes the organization of the information in the passage?

• A. cause-effect
• B. chronological sequence
• C. problem-solution
• D. comparison-contrast

Correct answer: B

Rationale: The passage is organized in a chronological sequence, starting from the reign of King Charles II, proceeding to his death without a legitimate heir, the ascension of his brother James II, and the events that followed with the birth of James II's son and the subsequent fleeing of the family. The passage then covers the rejection of the young James as heir, the rise of the Jacobites, and the defeat at the Battle of Culloden in 1746. Each event is presented in the order in which they occurred. The other answer choices are incorrect: cause-effect implies a relationship of events leading to each other, problem-solution focuses on identifying issues and resolving them, and comparison-contrast involves highlighting similarities and differences between subjects, none of which are the primary organizational structure of the passage.
