Answers
Q1: What is Reductionism?
A: reducing complex systems to simpler components that are more manageable to study
Q2: What is Biology?
A: the study of life and living things
Q3: What is the Biosphere?
A: Consists of all life on Earth and all parts of the Earth in which life exists, including land,
water, and the atmosphere.
Q4: What are the 5 components found at any biological level?
A: 1. organization
2. information (genetic)
3. energy and matter
4. interactions (behaviorally, chemically)
5. evolution
Q5: How do we study life?
A: scientific method
Q6: What are the steps of the scientific method?
A: 1. problem
2. hypothesis
3. procedure
4.analyze
5.conclusion
Q7: How old do scientists believe the Earth is? How long was there no life?
A: 4.2 billion years old ; 1 billion years
Q8: What is the OparinHaldane hypothesis?
A: reducing atmosphere facilitates organic molecule formation
, Q9: What is the MillerUrey experiment?
A: water, methane, ammonia, carbon dioxide were the gases
attempt to simulate the Earth 4.6 billion years ago
amino acids, the building blocks of life were reproduced from gases that were believed
to exist when the Earth was formed and the input of energy
Q10: What is the warm puddle hypothesis?
A: life began from single celled organisms arising from warm puddles most likely near
volcanic activity
most accurate as of 2021
Q11: What are the 2 major characteristics of life?
A: ability to replicate
ability to perform some type of metabolic activity
Q12: What are the 4 conditions for chemical origin of life?
A: 1. abiotic, nonliving, synthesis of small organic molecules ( amino acids, nitrogenous
bases)
2. joining of these organic molecules into macromolecules (proteins, nucleic acids)
3. packaging of these organic molecules into protocells
4. origin of selfreplicating molecules that eventually lead to inheritance
Q13: What was the first genetic material most likely?
A: RNA; can function as an enzyme catalyst = ribozyme
Q14: What is taxonomy?
A: the science of naming and classifying organisms
Q15: Who is the father of taxonomy?
A: Carolus Linnaeus
Q16: What is the order of classification?
A: Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
Q17: What is the Systema Nature?
A: first encyclopedia of life, written by Linnaeus
