1. If a student accidentally splashes a chemical solution into their eye, what immediate action should be taken inside the lab?

  1. A. Wipe eyes vigorously with paper towels
  2. B. Apply hand sanitizer directly to eyelids
  3. C. Rinse eyes thoroughly at the eyewash station
  4. D. Wait for the experiment to end before seeking help
Show answer

Answer: C

The eyewash station provides an immediate continuous water stream to flush out chemical or biological contaminants from the eyes.

2. Prior to incineration, Category C biological waste (animal tissues) must be:

  1. A. Wrapped in paper and left on open benches
  2. B. Mixed with Category A sharp items
  3. C. Wrapped in absorbent material, sealed in biohazard bags, and frozen
  4. D. Diluted with tap water and poured down standard sinks
Show answer

Answer: C

Animal carcasses (Category C) are wrapped in absorbent material, sealed in biohazard bags, and frozen to prevent decay before incineration.

3. Which biological discipline focuses on the study of inheritance, DNA structure, and variations in organisms?

  1. A. Taxonomy
  2. B. Genetics
  3. C. Histology
  4. D. Morphology
Show answer

Answer: B

Genetics is the branch of biology concerned with genes, heredity, and genetic variation.

4. Which field of biology specifically studies the interactions between living organisms and their environment?

  1. A. Ecology
  2. B. Physiology
  3. C. Anatomy
  4. D. Genetics
Show answer

Answer: A

Ecology is the study of interactions between living organisms and their biotic and abiotic environment.

5. Which of the following is a rule when drawing biological diagrams?

  1. A. Shade structures to show three-dimensional depth
  2. B. Draw overlapping and crossed label lines
  3. C. Use clear, un-shaded continuous lines with a sharp pencil
  4. D. Label diagrams using decorative cursive script
Show answer

Answer: C

Biological drawings must feature clean, smooth line art without artistic shading or crossed label lines.

6. Which equipment should be used to protect the user from handling volatile, toxic chemical fumes in a biology lab?

  1. A. Fume hood
  2. B. Laminar flow cabinet
  3. C. Biological safety cabinet
  4. D. Safety shower
Show answer

Answer: A

A fume hood expels harmful chemical fumes and volatile vapors away from the laboratory environment.

7. What is the key difference between a Fume Hood and a Laminar Flow Cabinet?

  1. A. Fume Hoods protect the worker from fumes; Laminar Flow Cabinets protect samples from contamination.
  2. B. Fume Hoods heat samples; Laminar Flow Cabinets freeze samples.
  3. C. Fume Hoods are used for animal dissections; Laminar Flow Cabinets are used for sharp tools.
  4. D. Fume Hoods discard solid waste; Laminar Flow Cabinets recycle plastic waste.
Show answer

Answer: A

Fume Hoods protect the user from volatile chemicals, while Laminar Flow Cabinets provide sterile filtered air to protect samples from airborne contamination.

8. How should sharp biological wastes, such as used scalpel blades and glass syringe needles, be disposed of?

  1. A. Placed directly into standard biohazard plastic bags
  2. B. Placed in puncture-proof sharp waste bins
  3. C. Washed with detergent and discarded in trash cans
  4. D. Melted in an open flame before sink disposal
Show answer

Answer: B

Sharp items (Category A waste) must be placed in rigid, puncture-resistant containers to prevent needle-stick injury.

9. A researcher is studying the molecular structure and chemical processes within plant cells. Which two biological fields are being applied?

  1. A. Zoology and Ecology
  2. B. Botany and Biochemistry
  3. C. Genetics and Anatomy
  4. D. Microbiology and Physiology
Show answer

Answer: B

Botany deals with plant life, while biochemistry focuses on chemical processes within cells.

10. Which axis on a line graph should represent the responding variable?

  1. A. X-axis (Horizontal axis)
  2. B. Y-axis (Vertical axis)
  3. C. Z-axis (3D depth axis)
  4. D. Either X-axis or Y-axis interchangeably
Show answer

Answer: B

In standard scientific data representation, the responding variable is plotted on the vertical Y-axis.
