English Grammar
1. Identify the clause that acts as an adverbial modifier in the sentence: "While the movie was playing, I snuck out to get popcorn."
- A. While the movie was playing
- B. I snuck out
- C. to get popcorn
- D. the movie was playing
Correct answer: A
Rationale: The clause "While the movie was playing" modifies the verb "snuck out," describing the time of the action.
2. What is the SI unit of measurement for acceleration?
- A. Meters per second (m/s)
- B. Newton (N)
- C. Meters (m)
- D. Meters per second squared (m/s²)
Correct answer: d
Rationale: Acceleration is measured in meters per second squared (m/s²) in the SI unit system.
3. The urethra is the tube that carries urine from the bladder to the outside of the body. How does urine flow through the urethra?
- A. Continuously
- B. Only when the bladder is completely full
- C. Under voluntary control of sphincter muscles
- D. A combination of b) and c)
Correct answer: C
Rationale: The correct answer is C: "Under voluntary control of sphincter muscles." The urethra is the tube responsible for carrying urine from the bladder to the outside of the body. Urine flow through the urethra is not continuous but rather under voluntary control. The sphincter muscles, located at the opening of the bladder and urethra, help control the release of urine. This control allows individuals to regulate when and where they empty their bladder, providing a mechanism to prevent involuntary leakage of urine. Therefore, option C accurately describes how urine flows through the urethra.
4. What is the name of the cartilage flap that covers the trachea during swallowing, preventing food from entering the airway?
- A. Epiglottis
- B. Glottis
- C. Larynx
- D. Pharynx
Correct answer: A
Rationale: The correct answer is A: Epiglottis. The epiglottis is a cartilage flap located at the base of the tongue that covers the trachea during swallowing. Its main function is to prevent food or liquid from entering the airway and instead directs them towards the esophagus. The glottis (option B) is the space between the vocal cords in the larynx, not a cartilage flap. The larynx (option C) is the voice box located in the throat, and the pharynx (option D) is the throat cavity connecting the mouth and the esophagus. Understanding the role of the epiglottis in protecting the airway during swallowing is crucial for maintaining proper respiratory function.
5. Which of the following is NOT a route of transmission for a sexually transmitted infection (STI)?
- A. Unprotected sexual contact
- B. Sharing contaminated needles
- C. Deep kissing
- D. Mother to child during childbirth
Correct answer: C
Rationale: Rationale: A) Unprotected sexual contact is a common route of transmission for sexually transmitted infections (STIs) as many STIs are spread through genital, anal, or oral sex without the use of barrier protection such as condoms. B) Sharing contaminated needles can also transmit STIs such as HIV and hepatitis B and C, especially among individuals who inject drugs. C) Deep kissing, while it can transmit certain infections like herpes simplex virus (HSV-1) or cytomegalovirus (CMV), is not a common route of transmission for most STIs. D) Mother to child transmission during childbirth can occur with certain STIs such as HIV, syphilis, and herpes, where the infection can be passed from the mother to the baby during delivery. Therefore, deep kissing (option C) is the correct answer as it is not a typical route of transmission for most STIs.
6. Antigenic variation, a common strategy used by some viruses, allows them to:
- A. Produce toxins
- B. Evade the immune system
- C. Survive outside a host
- D. Replicate rapidly
Correct answer: B
Rationale: Rationale: Antigenic variation is a strategy used by some viruses to evade the host's immune response. By constantly changing their surface antigens, viruses can avoid recognition and destruction by the immune system. This allows the virus to persist in the host and continue replicating, leading to prolonged infection and potential transmission to other hosts. Antigenic variation does not directly involve the production of toxins, survival outside a host, or rapid replication, making options A, C, and D incorrect in this context.
