COMPLETE QUESTIONS AND ANSWERS
GRADED A+ FULL SOLUTION
◉ Biological Organization. Answer: 1. Biosphere
2. Ecosystem
3. Communities
4. Populations
5. Organisms
6. Organs and Organ Systems
7. Tissues
8. Cells
9. Organelles
10. Molecules
◉ Properties of life. Answer: 1. Order
2. Regulation
3. Energy Processing
4. Evolutionary Adaptation
5. Response to the Environment
6. Reproduction
,7. Growth and Development
◉ Reductionism. Answer: reducing a complex system into smaller
parts. each level of the system shows correlation between structure
and function. EX: study of molecular structure of DNA helps us to
understand chemical basis of inheritance.
◉ Unity (Evolution). Answer: the process of change that has
transformed life on earth. Biological unity is similarities between
organisms due to evolution from a common ancestor. organisms of a
common ancestor. EX: wings/arms and their unity coming from
evolution.
◉ Three Domains of Life. Answer: Domain Bacteria (prok.)
Domain Archaea (prok.)
Domain Eukarya (euka., plants, fungi, animals, protests)
◉ What is a protest?. Answer: single cell eukaryotic organisms not
classified in their own kingdom but in the domain eukarya
◉ Eukaryotic organisms/cells. Answer: A eukaryotic cell has
membrane-enclosed organelles, the largest of which is usually the
nucleus
, ◉ Prokaryotic organisms/cells. Answer: A prokaryotic cell is simpler
and usually smaller, and does not contain a nucleus or other
membrane-enclosed organelles
◉ What do fossils tell us about the natural history of life on earth?.
Answer: tells us about ancestor species that don't exist on earth
anymore. we can analyze fossil records and find evidence of current
species
◉ Hierarchal Classification. Answer: classifies species from the most
inclusive (domain) to the most specific species.
Levels:
