CCBC BIO 110 EXAM 2 |2025-2026 LATEST UPDATED|145 REAL EXAM QUESTIONS AND
ANSWERS | 100% RATED CORRECT | 100% VERFIED | ALREADY GRADED A+
1. What are the characteristics of life: 1. Organization and complexity (uses energy to actively maintain)
2. Responds to the environment: Actively maintain a set of internal conditions within ideal ranges (homeostasis) 3.
Growth and metabolism
4. Reproduction/heredity
5. Evolve
2. At the most basic level, cells come in two types:: Prokaryotic and Eukaryotic
3. Prokaryotic cells: bacteria and archaea
4. Eukaryotic cells: animals, plants, fungi, & protists
5. What the one major difference between Prokaryotic and Eukaryotic cells: eukaryotic cells can be up to a 1000
times larger than prokaryotic cells
6. Cell volume represents: demand - lots of metabolism occurring (greater volume
= greater demand)
7. Cell surface area represents: supply - everything that enters/exits the cell must go through its surface area
8. In order for cells to survive: SUPPLY e DEMAND
9. As the cell size increases: cell volume (demand) increases faster than the cell's surface area (supply)
10. What eventually happens to cells: demand begins to exceed supply 11. Why are cells small: remaining small
allows cells to maintain a workable surface area to volume ratio
12. Prokaryotic cell are divided into two domains: - Bacteria (also called eubacteria)

- Archaea (extremophiles)
13. Prokaryotic cells are the dominant forms of life in terms of both: biomass and diversity
14. Number of prokaryotic cells in a handful of soil is: roughly equal to the number of people that have ever lived
(~100 billion)
15. Number of prokaryotic cells that live on/in a human body: (~40 trillion) which is greater than the number of
eukaryotic cells that make up the human body (~30 trillion)
16. Differences of prokaryotic cell between eukaryotic cell: - No nucleus, DNA is in an area of the cell, the
nucleoid
- No internal membrane system
- All prokaryotes have a cell wall
17. Prokaryotes cell wall: a protective outer barrier composed of peptidoglycans 18. Similarities of prokaryotic cell
between eukaryotic cell: - All use DNA as their genetic material
- All have an outer plasma membrane (Phospholipid bilayer)
- All have cytoplasm
- All have ribosomes, the universal organelle, responsible for synthesizing proteins
19. Cytoplasm: a semi solid substance that contains the cell's internal components 20. Prokaryotic cell structure:
21. Eukaryotic Structure: - A distinctive feature of eukaryotic cells is their internal compartmentalization
> Possible because of an internal membrane system
