1. Which of the following is NOT a function of the cardiovascular system?

• A. Transporting oxygen to cells
• B. Maintaining blood pressure
• C. Carrying waste products to the kidneys for removal
• D. Initiating the immune response

Correct answer: D

Rationale: The cardiovascular system is responsible for transporting oxygen to cells (A), maintaining blood pressure (B), and carrying waste products to the kidneys for removal (C). Initiating the immune response (D) is not a function of the cardiovascular system. The immune response is primarily carried out by the immune system, which includes organs like the spleen, thymus, and lymph nodes. Therefore, option D is the correct answer as it pertains to a function outside the scope of the cardiovascular system, making it the odd one out among the given choices.

2. Which of the following compound sentences is punctuated correctly?

• A. The Forlows would be spending two weeks in Greece and Turkey.
• B. She was awake the minute the sun came up; although she had been up late the night before.
• C. Diana stepped out into the rain, but she had to turn immediately back inside for an umbrella.
• D. Aziz was astonished; he had never seen horses in the wild before.

Correct answer: D

Rationale: Choice D is the correct answer because it correctly punctuates the compound sentence with a semicolon separating the two independent clauses. The use of a semicolon is appropriate when two closely related independent clauses are joined without a coordinating conjunction. Choices A, B, and C have incorrect punctuation or conjunction usage. Choice A incorrectly uses a comma before 'and,' while Choice B uses 'though' which is not the best conjunction to join the two clauses. Choice C also lacks appropriate punctuation to separate the two independent clauses.

3. What is the significance of studying pedigrees in human genetics?

• A. Predicting the exact outcome of genetic crosses in humans.
• B. Tracing the inheritance of complex traits with multiple contributing genes.
• C. Identifying carriers of dominant genetic disorders.
• D. Determining the risk of acquiring a specific mutation de novo.

Correct answer: B

Rationale: Pedigrees are diagrams that show the relationships within a family and can be used to track the inheritance patterns of specific traits or diseases. While pedigrees can provide information on the inheritance of single gene disorders (such as identifying carriers of dominant genetic disorders, as mentioned in option C), their primary significance lies in studying complex traits with multiple contributing genes. These traits do not follow simple Mendelian inheritance patterns and are influenced by both genetic and environmental factors. By analyzing pedigrees, researchers can identify patterns of inheritance for complex traits, such as polygenic diseases or traits influenced by gene-environment interactions. Therefore, option B is the most appropriate choice as it captures the main significance of studying pedigrees in human genetics.

4. Which of the following occurred first in Alexander Graham Bell's life?

• A. Helped found the National Geographic Society.
• B. Developed a metal detector.
• C. Moved to Canada.
• D. Invented the telephone.

Correct answer: C

Rationale: Alexander Graham Bell moved to Canada early in his life, before inventing the telephone and developing other technologies. Choice A is incorrect because Bell did not help found the National Geographic Society; this happened years after his major inventions. Choice B is incorrect because Bell developed a metal detector after inventing the telephone. Choice D is incorrect because Bell invented the telephone after moving to Canada.

5. Which word is misspelled?

• A. accommodate
• B. acquiesce
• C. circumstance
• D. indelible

Correct answer: C

Rationale: The correct answer is C. The word 'circumstance' is misspelled in the given choices. 'Accommodate,' 'acquiesce,' and 'indelible' are spelled correctly. It is important to pay attention to the spelling of words to ensure clear and accurate communication. 'Circumstance' is a common word, but in this context, it is intentionally misspelled to test your attention to detail.
