1. Which organelle is responsible for packaging and secreting proteins into the extracellular space?

• A. Golgi apparatus
• B. Mitochondria
• C. Ribosomes
• D. Endoplasmic reticulum

Correct answer: A

Rationale: Rationale: A) Golgi apparatus: The Golgi apparatus is responsible for modifying, sorting, and packaging proteins into vesicles for secretion outside the cell or for use within the cell. B) Mitochondria: Mitochondria are known as the powerhouse of the cell and are responsible for generating energy in the form of ATP through cellular respiration. They are not involved in packaging and secreting proteins. C) Ribosomes: Ribosomes are responsible for protein synthesis, where they translate mRNA into proteins. They are not involved in packaging and secreting proteins into the extracellular space. D) Endoplasmic reticulum: The endoplasmic reticulum (ER) plays a role in protein synthesis and folding, but it is the rough ER specifically that is involved in synthesizing proteins that are then transported to the Golgi apparatus for further processing and packaging. The Golgi apparatus is primarily responsible for packaging and secreting proteins

2. Which statement best summarizes the main argument of the passage?

• A. Smart cities are a revolutionary solution to all urban challenges.
• B. Technology alone can fix modern cities' problems.
• C. Smart cities offer potential but require careful consideration of data privacy and ethical implications.
• D. Traditional city planning methods are superior to implementing smart technology.

Correct answer: C

Rationale: The passage acknowledges both the potential and concerns surrounding smart cities, making it the most accurate summary.

3. The ureters are paired tubes that transport urine from the:

• A. Bladder to the urethra
• B. Kidneys to the bladder
• C. Urethra to the kidneys
• D. Skin to the kidneys

Correct answer: B

Rationale: The correct answer is B: 'Kidneys to the bladder.' The ureters are paired tubes that carry urine from the kidneys to the bladder. Once urine is produced in the kidneys, it travels through the ureters to be stored in the bladder until it is eliminated from the body through the urethra. Option A, 'Bladder to the urethra,' is incorrect because the ureters transport urine from the kidneys to the bladder, not from the bladder to the urethra. Option C, 'Urethra to the kidneys,' and option D, 'Skin to the kidneys,' are both inaccurate as they do not describe the correct direction of urine flow in the urinary system. Understanding the anatomy and function of the urinary system is essential for comprehending how urine is produced and excreted by the body.

4. She knows that there are external forces that influence changes in his unit. Which of the

• A. Memo from the CEO to cut down on electrical consumption
• B. Demands of the labor sector to increase wages
• C. Low morale of staff in her unit
• D. Exacting regulatory and accreditation standards

Correct answer: A

Rationale: The correct answer is option A: 'Memo from the CEO to cut down on electrical consumption.' This choice represents an external force that can influence changes in the unit by setting a directive from top management to reduce electricity usage, impacting operations and decisions within the unit. While options B, C, and D may also affect the unit to some extent, they are not as directly tied to external influences as the CEO's memo. The demands of the labor sector (option B) and low staff morale (option C) are internal factors, while regulatory and accreditation standards (option D) are more overarching guidelines rather than specific external forces impacting the unit. Therefore, the most direct and relevant external force in this scenario is the directive from the CEO, making option A the correct choice.

5. Cartilage, a type of connective tissue, provides flexible support in various structures. Which of these does NOT contain cartilage?

• A. Ears
• B. Joints
• C. Muscles
• D. Nose

Correct answer: C

Rationale: Muscles do not contain cartilage. Cartilage is a specialized type of connective tissue that provides flexible support in structures like the ears, joints, and nose. Ears have cartilage in their structure, which helps maintain their shape and flexibility. Joints, such as the knee and elbow, have cartilage to cushion and reduce friction between bones. The nose also contains cartilage, forming its shape and structure. Muscles, on the other hand, are made up of muscle tissue and do not contain cartilage. Therefore, muscles are the correct answer as they do not contain cartilage, unlike the other options.

6. What happens to the speed of a sound wave when it travels from air to water?

• A. It increases because water is denser.
• B. It decreases because water is denser.
• C. It remains the same.
• D. Speed depends on the frequency, not the medium.

Correct answer: A

Rationale: Sound waves travel faster in denser mediums like water compared to air due to stronger interactions between particles.
