1. Where does the electron transport chain occur in the cell?

• A. Cytosol
• B. Golgi apparatus
• C. Inner mitochondrial membrane
• D. Nucleus

Correct answer: C

Rationale: The electron transport chain occurs in the inner mitochondrial membrane. This process is crucial for the generation of ATP, the cell's energy currency. Choice A (Cytosol) is incorrect as the electron transport chain does not take place in the cytosol. Choice B (Golgi apparatus) is also incorrect as the Golgi apparatus is involved in modifying, sorting, and packaging of proteins. Choice D (Nucleus) is incorrect as the nucleus houses the cell's genetic material but is not the location of the electron transport chain.

2. Which of the following pathologies is caused by a virus?

• A. Asthma
• B. Cystic Fibrosis
• C. Epiglottitis
• D. Influenza

Correct answer: D

Rationale: The correct answer is D, Influenza. Influenza is a viral infection caused by the influenza virus. Asthma and cystic fibrosis are not caused by viruses. Asthma is a chronic respiratory condition related to inflammation and airway constriction, while cystic fibrosis is a genetic disorder affecting the lungs and other organs. Epiglottitis is most commonly caused by bacteria, particularly Haemophilus influenzae type B, rather than a virus.

3. What is surgically altered during a vasectomy?

• A. Vas deferens
• B. Glans penis
• C. Prostate
• D. Urethra

Correct answer: A

Rationale: During a vasectomy, the vas deferens is surgically altered or cut to prevent the transport of sperm from the testicles to the urethra. This procedure is a form of permanent male sterilization. The glans penis, prostate, and urethra are not surgically altered during a vasectomy. Therefore, the correct answer is the vas deferens (Choice A), as it is the structure specifically targeted and modified in this procedure. The glans penis (Choice B) is the sensitive tip of the penis, the prostate (Choice C) is a gland vital for semen production but not involved in a vasectomy, and the urethra (Choice D) is the tube that carries urine and semen but is not surgically altered in a vasectomy.

4. Which of the following lobes of the brain is primarily responsible for vision?

• A. Frontal
• B. Occipital
• C. Parietal
• D. Temporal

Correct answer: B

Rationale: The occipital lobe is primarily responsible for processing visual information. It contains the primary visual cortex, which plays a key role in interpreting visual stimuli. The frontal lobe is more associated with functions such as decision-making and problem-solving, making choice A incorrect. The parietal lobe is involved in processing sensory information but not specifically vision, making choice C incorrect. The temporal lobe is responsible for functions like memory and auditory processing, so choice D is also incorrect.

5. Which type of tissue provides support and structure to the body?

• A. Muscle tissue
• B. Connective tissue
• C. Nervous tissue
• D. Epithelial tissue

Correct answer: B

Rationale: Connective tissue is the correct answer as it provides support, structure, and strength to the body by holding tissues and organs in place. Muscle tissue is primarily responsible for movement, nervous tissue for communication, and epithelial tissue for covering and lining surfaces. While muscle tissue allows for voluntary and involuntary movement, nervous tissue transmits electrical signals, and epithelial tissue acts as a protective barrier and is involved in absorption and secretion. Therefore, in the context of providing support and structure, connective tissue is the most appropriate choice.
