Biology

1. What is the process of removing waste products from the cell called?

A. Exocytosis
B. Endocytosis
C. Phagocytosis
D. Pinocytosis

Correct answer: A

Rationale: Rationale: A) Exocytosis is the process by which cells expel waste products or other substances by fusing a vesicle containing the waste with the cell membrane, releasing its contents outside the cell. This process is essential for maintaining cellular homeostasis by removing waste products from the cell. B) Endocytosis is the process by which cells take in substances by engulfing them in a vesicle formed from the cell membrane. This process is the opposite of exocytosis and is used to bring substances into the cell. C) Phagocytosis is a type of endocytosis where cells engulf solid particles or other cells to form a vesicle called a phagosome. This process is used by immune cells to engulf and destroy pathogens. D) Pinocytosis is a type of endocytosis where cells engulf fluids and dissolved solutes. This process allows cells to take in nutrients and

2. A decorative box has a rectangular base (20cm by 15cm) and a hemispherical top with the same diameter as the base. What is the total surface area of the box (excluding the base)?

A. 825 sq cm
B. 1075 sq cm
C. 1325 sq cm
D. 1575 sq cm

Correct answer: C

Rationale: Calculate the surface area of the lateral sides and the hemisphere, then add them up.

3. What is the main concern the author raises about AI?

A. Its limitations in achieving true intelligence and emulating human consciousness.
B. Its potential for misuse in warfare and autonomous weapons systems.
C. Its detrimental impact on the environment and resource consumption.
D. Its ethical implications related to bias, privacy, and job displacement.

Correct answer: D

Rationale: The passage explicitly mentions concerns about bias, privacy, and job displacement, making D the main concern highlighted.

4. Urine, the liquid waste product of the body, travels from the kidneys to the bladder through tubes called:

A. Ureters
B. Urethra
C. Nephrons
D. Renal pelvis

Correct answer: A

Rationale: The correct answer is A: Ureters. Ureters are the tubes that connect the kidneys to the bladder, allowing urine to flow from the kidneys to the bladder for storage before elimination. The urethra, option B, is the tube through which urine is expelled from the bladder out of the body. Nephrons, option C, are the functional units of the kidneys responsible for filtering blood and producing urine. The renal pelvis, option D, is a part of the kidney where urine collects before entering the ureters. Therefore, the correct answer is A, as the ureters specifically carry urine from the kidneys to the bladder.

5. The following are basic steps in the controlling process of the department. Which of the

A. Measure actual performance
B. Set nursing standards and criteria
C. Compare results of performance to standards and objectives
D. Identify possible courses of action

Correct answer: A

Rationale: The correct answer is A: 'Measure actual performance.' In the controlling process of a department, measuring actual performance is a crucial step to assess how well the department is performing compared to set standards and objectives. By measuring actual performance, managers can identify any deviations from the established criteria and take necessary corrective actions. Setting nursing standards and criteria (option B) is typically done before the controlling process begins, to provide a benchmark for measuring performance. Comparing results of performance to standards and objectives (option C) is done after measuring actual performance. Identifying possible courses of action (option D) is part of the corrective action phase that follows measuring actual performance. Therefore, option A is the most appropriate step in the controlling process of a department.
