1. The science of classifying organisms into different groups based on their evolutionary relationships is called:

• A. Taxonomy
• B. Microbiology
• C. Genetics
• D. Epidemiology

Correct answer: A

Rationale: Rationale: Taxonomy is the science of classifying organisms into different groups based on their evolutionary relationships. It involves identifying, naming, and categorizing living organisms according to their similarities and differences. Microbiology (option B) is the study of microorganisms, Genetics (option C) is the study of genes and heredity, and Epidemiology (option D) is the study of the distribution and determinants of health-related states or events in populations.

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. A temporary loss of consciousness due to insufficient blood flow to the brain is called:

• A. Stroke
• B. Seizure
• C. Syncope (fainting)
• D. Coma

Correct answer: C

Rationale: The correct answer is C: "Syncope (fainting)". Syncope is a temporary loss of consciousness caused by insufficient blood flow to the brain. During syncope, there is a brief interruption in the brain's blood supply, leading to a temporary loss of consciousness and muscle tone. This is different from a stroke (A), which is caused by a blockage or rupture of blood vessels in the brain, resulting in permanent damage. Seizures (B) involve abnormal electrical activity in the brain and can cause a variety of symptoms, including loss of consciousness, but they are not specifically due to insufficient blood flow. Coma (D) is a state of prolonged unconsciousness where a person is unresponsive and cannot be awakened. Therefore, the most appropriate term for a temporary loss of consciousness due to insufficient blood flow to the brain is syncope.

4. Which organelle is responsible for the final stages of protein modification and packaging for secretion in animal cells?

• A. Rough endoplasmic reticulum (RER)
• B. Smooth endoplasmic reticulum (SER)
• C. Ribosomes
• D. Golgi apparatus

Correct answer: D

Rationale: The Golgi apparatus is responsible for the final stages of protein modification and packaging for secretion in animal cells. After proteins are synthesized in the rough endoplasmic reticulum (RER) and modified in the Golgi apparatus, they are packaged into vesicles for secretion. The smooth endoplasmic reticulum (SER) is involved in lipid and carbohydrate metabolism, while ribosomes are responsible for protein synthesis on the RER. Therefore, the Golgi apparatus is the correct organelle for the final processing and packaging of proteins for secretion in animal cells.

5. 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.

6. What is the main function of lysosomes?

• A. Breaking down and recycling cellular waste
• B. Storing carbohydrates
• C. Synthesizing lipids
• D. Transcribing DNA into mRNA

Correct answer: A

Rationale: The main function of lysosomes is to break down and recycle cellular waste. Lysosomes contain digestive enzymes that help break down old or damaged organelles, foreign substances, and cellular debris. This process, known as autophagy, helps maintain cellular health and proper functioning. Storing carbohydrates (option B) is not a function of lysosomes; carbohydrates are typically stored in the form of glycogen in the cytoplasm or as starch in plant cells. Synthesizing lipids (option C) is primarily done by the endoplasmic reticulum and not by lysosomes. Transcribing DNA into mRNA (option D) is a function of the nucleus and not the lysosomes. Therefore, the correct answer is A: breaking down and recycling cellular waste.
