Edition.
1. Scientific Method - Answer Observations and Question(s)
→ Formulate a testable hypothesis (search library)
→ Make predictions
→ Conduct a controlled experiment
→ Collect data
→ Formulate a theory
2. Prokaryotic vs. Eukaryotic - Answer Prokaryotic cells:
- No membrane bound organelles
- No nuclear membrane
Eukaryotic cells:
- have membrane bound organelles
- Have a nuclear membrane
3. What characterizes a Prokaryotic cell? - Answer A prokaryote is a simple, single-celled
(unicellular) organism that lacks an organized nucleus or any other membrane-bound organelle
4. What characterizes an Eukaryotic cell? - Answer Eukaryotic cells are larger than
prokaryotic cells and have a "true" nucleus, membrane-bound organelles, and rod-shaped
chromosomes.
The nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes.
5. What sums up the theme of biology? - Answer -Evolution
6. Common structures found in all living things. - Answer A) Order: complexity of
organization (structures)
B) Regulation (body temp)
C) Organisms Grow and Develop
D) Organisms Transform Energy
1d) Autotrophic - self-feeders (plants)
,2d) Heterotrphic - Other feeders (animals)
E) Organisms Respond to Stimuli/ Environment
F) Reproduction
G) Live Evolves and Adapts to the environment
7. Hierarchy of Biological Organization: - Answer From Most Inclusive to Least inclusive
Biosphere :all of earths ecosystem
Biomes: large scale communities
Ecosystem: community interactions
Community: populations of species in same area
Population: group of same species
Organism: species
Organ system: ex cardiovascular system
Organ: ex Heart
Tissue: heart tissue
Cells
Organelles
Molecules
Atoms
8. Domains and their characteristics - Answer 1. Eubacteria (prokaryotic)
-cell wall has peptidoglycan, all other bacteria that are not included in the Archaea domain
2. Archaea: oldest known domain, ancient forms of bacteria.
3. Eukarya: all the organisms that are eukaryotic or contain membrane-bound organelles and
nuclei
9. Kingdoms and their unique characteristics: - Answer 1. Eubacteria: Bacteria
-single-celled bacterial organisms. This kingdom makes up most of the bacteria in the world
2. Archaebacteria:
- single-celled organisms that live and thrive in extreme conditions and oldest living
3. Protista:
- Simple multi or unicellular
4. Plantae:
-Plants (multi-celled, complex organisms and are considered Autotrophic)
5. Fungi:
, - Yeast and mushrooms (multicellular)
6. Animalia
- animals (complex multicellular)
10. What dictates why an organism lives in a particular area? - Answer The environment and
the resources available for the organism to use
11. What is in a nucleotide? - Answer Nitrogen base + sugar (ribose or deoxyribose) and
phosphate group
12. What is the definition of a species, population, community, ecosystem and biome? - Answer
-Species: a class of individuals having common attributes and designated by a common name
specifically: a logical division of a genus or more comprehensive class confessing sins in species
and in number
-Population: localized groups of organisms belonging to the same species
-Community: populations of species living in the same area
-Ecosystem: Community interactions
-Biome: large scale communities
13. Charles Darwin and natural selection - Answer Charles Darwin proposed natural selection
in his book "on the origin of species by means of natural selection"
- where the environmental factors made it so certain traits were passed onto offspring.
14. Taxonomy - Answer Def: The naming and classifying of organisms.
Hierarchy of life forms: most to least inclusive
1.Domain
2. Kingdom
3. Phylum
4. Class
5. Order
6. Family
7. Genus
8. Species
