1. A balsam plant possesses a taproot system and leaves with network venation. How is it classified?

  1. Monocotyledonous plant
  2. Non-vascular spore plant
  3. Dicotyledonous plant
  4. Gymnosperm conifer
Show answer

Answer: C

Dicotyledonous plants feature taproots and netted (network) leaf venation.

2. Which characteristic applies to all mammals EXCEPT monotremes (e.g., the platypus)?

  1. Having hair or fur on their body
  2. Giving birth to live young
  3. Breathing through lungs
  4. Being homeothermic
Show answer

Answer: B

Platypuses and echidnas are monotremes—rare egg-laying mammals. All other mammals give birth to live young.

3. Which trait is shared by both reptiles and birds?

  1. Both maintain a constant body temperature (homeothermic)
  2. Both undergo internal fertilisation
  3. Both breathe through moist skin
  4. Both possess dry scales across their entire body
Show answer

Answer: B

Both reptiles and birds reproduce through internal fertilisation before laying eggs.

4. Which feature is unique to non-flowering coniferous plants?

  1. They reproduce by producing spores
  2. They produce flowers with net-veined leaves
  3. They produce seeds inside cones instead of flowers
  4. They lack a vascular transport system
Show answer

Answer: C

Conifers are non-flowering vascular plants that bear seeds inside specialized structures called cones.

5. Which animal group is homeothermic, possesses feathers, and undergoes internal fertilisation?

  1. Mammals
  2. Reptiles
  3. Birds
  4. Amphibians
Show answer

Answer: C

Birds are warm-blooded (homeothermic) vertebrates covered in feathers that reproduce via internal fertilisation.

6. Which plant group reproduces by producing spores and lacks a vascular system?

  1. Ferns
  2. Mosses
  3. Conifers
  4. Dicotyledons
Show answer

Answer: B

Mosses are non-vascular plants that reproduce via spores. Ferns also use spores but possess a vascular transport system.

7. What is an endemic species?

  1. A species introduced from another country
  2. A species that is completely extinct in the wild
  3. A species found naturally only in a specific geographic area
  4. A species that can survive in all global climates
Show answer

Answer: C

Endemic species are native and restricted to a particular geographical region (e.g., the Proboscis Monkey in Borneo).

8. To which invertebrate group does an earthworm belong?

  1. Invertebrate without legs and with a non-segmented body
  2. Invertebrate with 3 pairs of jointed legs
  3. Invertebrate without legs and with a segmented body
  4. Invertebrate with 4 pairs of jointed legs
Show answer

Answer: C

Earthworms and leeches are legless invertebrates with segmented bodies.

9. What primary function does a dichotomous key serve in biology?

  1. Determining the exact age of fossilized organisms
  2. Systematically identifying and classifying organisms using paired traits
  3. Measuring the exact rate of photosynthesis in green plants
  4. Calculating the total biomass of a ecosystem
Show answer

Answer: B

Dichotomous keys allow scientists to identify unknown organisms based on a series of choices between two contrasting physical features.

10. A student finds an invertebrate with 4 pairs of jointed legs. Which category does this animal belong to?

  1. Insects
  2. Crustaceans
  3. Arachnids
  4. Myriapods
Show answer

Answer: C

Arachnids (such as spiders and scorpions) possess exactly 4 pairs of jointed legs (8 legs).
