1. Which of the following is evidence that the controlling process is effective?

A. The things that were planned are done
B. Physicians do not complain.
C. Employees are contended
D. There is an increase in customer satisfaction rate.

Correct answer: A

Rationale: The correct answer is A: 'The things that were planned are done.' This is evidence that the controlling process is effective because it indicates that the organization is able to execute its plans successfully. When planned tasks and activities are completed as intended, it shows that the controlling function is ensuring that operations are on track and that deviations are being corrected. The completion of planned tasks also demonstrates that resources are being effectively utilized and that performance is being monitored and controlled. The other options do not directly relate to the effectiveness of the controlling process. Physicians not complaining, employees being contented, and an increase in customer satisfaction rate could be influenced by various factors and may not necessarily be solely attributed to the effectiveness of the controlling process.

2. Discern the INCORRECT function of the liver.

A. Bile production, aiding digestion.
B. Blood protein synthesis, such as albumin.
C. Glucose storage for energy regulation.
D. Filtration of waste products from the blood.

Correct answer: D

Rationale: Rationale: A) Correct - The liver produces bile, which aids in the digestion and absorption of fats in the small intestine. B) Correct - The liver is responsible for synthesizing blood proteins, including albumin, which helps maintain osmotic pressure in the blood. C) Correct - The liver stores glucose in the form of glycogen and helps regulate blood sugar levels by releasing glucose when needed. D) Incorrect - The liver does not filter waste products from the blood. Instead, the kidneys are responsible for filtering waste products from the blood and excreting them in the form of urine.

3. What are the different types of electromagnetic waves based on their wavelengths and frequencies?

A. Visible light, X-rays, radio waves, gamma rays
B. Sound waves, water waves, seismic waves, shock waves
C. Longitudinal waves, transverse waves, mechanical waves, non-mechanical waves
D. None of the above represent types of electromagnetic waves.

Correct answer: A

Rationale: Electromagnetic waves are classified based on their wavelengths and frequencies. Visible light, X-rays, radio waves, and gamma rays are all examples of electromagnetic waves with different wavelengths and frequencies. Sound waves, water waves, seismic waves, and shock waves are not electromagnetic waves but rather mechanical waves. Longitudinal waves, transverse waves, mechanical waves, and non-mechanical waves are classifications based on the direction of particle displacement and do not represent types of electromagnetic waves.

4. The fundamental units of structure and function in all living organisms, including humans, are termed:

A. Muscles
B. Organs
C. Tissues
D. Cells

Correct answer: D

Rationale: The correct answer is D: Cells. Cells are the fundamental units of structure and function in all living organisms, including humans. They are the building blocks of life, performing various functions necessary for an organism to survive and thrive. Muscles (A) are composed of muscle tissue, which is made up of muscle cells. Organs (B) are structures made up of different types of tissues working together. Tissues (C) are groups of cells that work together to perform specific functions within an organism. However, cells are the smallest unit of life and are responsible for carrying out all the essential processes needed for an organism to function.

5. Define "friction" in terms of opposing motion.

A. A force that increases motion
B. A force that accelerates motion
C. A force that opposes motion
D. A force that creates motion

Correct answer: c

Rationale: Friction acts opposite to the direction of motion, resisting or slowing down the movement of objects.

6. Which of the following is NOT a good scientific practice?

A. Which of the following is NOT a good scientific practice?
B. Selecting data that supports a desired outcome and ignoring contradictory evidence.
C. Peer-reviewing research findings before publication.
D. Replicating experiments to confirm results and validate findings.

Correct answer: B

Rationale: Scientific objectivity requires considering all data, regardless of whether it aligns with initial expectations. Selective bias can lead to inaccurate conclusions.
