1. In the town of Ellsford, there are approximately 1,450 residents who attend church weekly. If around 400 of them attend Catholic Churches, what percentage of churchgoers in Ellsford attends Catholic Churches?
- A. 23%
- B. 28%
- C. 36%
- D. 42%
Correct answer: B
Rationale: To find the percentage of churchgoers who attend Catholic Churches, divide the number of Catholic churchgoers by the total number of churchgoers and then multiply by 100. (400 ÷ 1,450) × 100 ≈ 27.59%, which rounds to 28%.
2. 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 pituitary gland, known as the master gland, regulates various endocrine glands by releasing specific hormones. The thyroid gland, adrenal glands, and parathyroid glands are directly controlled by the pituitary gland through hormones like thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), and parathyroid hormone (PTH) respectively. However, the pancreas, particularly the Islets of Langerhans, is not directly influenced by the pituitary gland. The pancreas is mainly governed by blood glucose levels and hormones such as insulin and glucagon, which play a crucial role in regulating blood sugar levels and metabolism. Therefore, the correct answer is C. Choice A, the thyroid gland, is controlled by the pituitary gland through TSH. Choice B, the adrenal glands, are regulated by the pituitary gland via ACTH. Choice D, the parathyroid glands, are under the direct control of the pituitary gland through PTH.
3. Which of the following blood proteins can destroy pathogens?
- A. Complement system
- B. Fibrinogen
- C. Major histocompatibility complex
- D. Platelets
Correct answer: A
Rationale: The correct answer is A: Complement system. The complement system is a vital component of the immune system responsible for destroying pathogens through various mechanisms like promoting inflammation, enhancing phagocytosis, and directly lysing pathogens. Fibrinogen is crucial for blood clotting, the major histocompatibility complex is involved in immune responses, and platelets aid in blood clotting and wound healing. However, none of these directly destroy pathogens as the complement system does.
4. Which of the following punctuation marks is used incorrectly in the sentence below?
- A. The semicolon after 'book.'
- B. The comma after 'long.'
- C. The comma after 'glasses.'
- D. The period at the end of the sentence.
Correct answer: C
Rationale: The comma after 'glasses' is used incorrectly in the sentence. Commas are not needed to separate the subject from the verb in this context. In this case, the subject 'She' is not separated from the verb 'wore,' making the comma unnecessary. The semicolon after 'book' is appropriate for separating two independent clauses, the comma after 'long' is correctly used for introductory elements, and the period at the end of the sentence is necessary for indicating the end of a complete thought.
5. What is the process of making copies of RNA from DNA called?
- A. Replication
- B. Transcription
- C. Translation
- D. DNA repair
Correct answer: B
Rationale: Transcription is the correct answer. Transcription is the process of making copies of RNA from DNA. During transcription, the enzyme RNA polymerase binds to a specific region of DNA and synthesizes a complementary RNA strand based on the DNA template. This process is essential for gene expression and protein synthesis in cells. Replication (option A) refers to the process of making copies of DNA, not RNA. Translation (option C) is the process of synthesizing proteins from mRNA, not making copies of RNA from DNA. DNA repair (option D) involves mechanisms that cells use to repair damaged DNA, not the process of making RNA copies from DNA.
