1. Which of the following is NOT a characteristic of living organisms?

• A. Made up of cells
• B. Able to reproduce
• C. Require energy
• D. Non-motile

Correct answer: D

Rationale: Rationale: A) Made up of cells: All living organisms are composed of one or more cells. This is a fundamental characteristic of life as defined by cell theory. B) Able to reproduce: One of the key characteristics of living organisms is their ability to reproduce and pass on genetic information to offspring. C) Require energy: Living organisms require energy to carry out various life processes such as growth, reproduction, and maintenance of homeostasis. This energy is obtained through processes like metabolism. D) Non-motile: While some living organisms may be non-motile (unable to move on their own), movement is a common characteristic of many living organisms. Motility allows organisms to respond to their environment, find food, escape predators, and carry out other essential activities.

2. What is the term for the particles moving around within a substance?

• A. Ions
• B. Atoms
• C. Molecules
• D. Kinetic energy

Correct answer: C

Rationale: In most cases, the particles moving within a substance are individual molecules or atoms, depending on the state of matter.

3. Which muscular pouch in the upper left abdomen stores food after swallowing and begins mechanical and chemical digestion?

• A. Esophagus
• B. Stomach
• C. Small intestine
• D. Large intestine

Correct answer: B

Rationale: The correct answer is B: Stomach. The stomach is the muscular pouch in the upper left abdomen that stores food after swallowing. It is responsible for beginning both mechanical and chemical digestion processes. Once food enters the stomach, it is mixed with gastric juices and enzymes that break down the food into smaller particles. The stomach also contracts and relaxes to further mix the food with digestive juices. The esophagus is a tube that connects the throat to the stomach and does not store food or participate in digestion. The small intestine and large intestine are parts of the digestive system, but they are not muscular pouches in the upper left abdomen responsible for storing and digesting food.

4. What is the term for the inflammation of the airways in the lungs, often causing wheezing and difficulty breathing?

• A. Pneumonia
• B. Emphysema
• C. Asthma
• D. Pleurisy

Correct answer: C

Rationale: The correct answer is C: "Asthma." Asthma is a chronic condition characterized by inflammation of the airways in the lungs, leading to symptoms like wheezing, shortness of breath, coughing, and chest tightness. Pneumonia (A) is an infection in the lungs caused by bacteria, viruses, or fungi. Emphysema (B) is a type of chronic obstructive pulmonary disease (COPD) characterized by damage to the air sacs in the lungs. Pleurisy (D) is inflammation of the lining of the lungs and chest cavity. Therefore, asthma best fits the description provided in the question, making it the correct answer.

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. Define the term "velocity" in relation to motion.

• A. Speed in a specific direction
• B. Distance traveled in a given time
• C. Rate of change of position
• D. Acceleration due to gravity

Correct answer:

Rationale: Velocity is the rate of change of position concerning direction, unlike speed which only refers to distance traveled per unit time.
