EDITION EXAM SCRIPT FULL QUESTIONS
AND SOLUTIONS
⫸ What are the distinguishing features of living organisms? Answer:
Complexity and organization, energy extraction and transformation,
response to changes, and self-replication with evolution.
⫸ What is the universal building block of living organisms? Answer:
The cell.
⫸ What defines the three domains of life? Answer: Differences in
cellular and molecular structures.
⫸ What are the main components of a bacterial cell? Answer: Cell wall
(peptidoglycan), cell membrane (lipid + protein), nucleoid (DNA +
protein), ribosomes (RNA + protein), pili (protein), flagella (protein),
cytoplasm (aqueous solution).
⫸ What is a key characteristic of eukaryotic cells? Answer: They have a
nucleus and membrane-enclosed organelles.
⫸ How do living organisms extract energy? Answer: From sunlight
(plants, green bacteria, cyanobacteria) or from fuels (animals, most
bacteria).
