How is science defined as a method of understanding?
✔✔ Science is an approach to knowledge focused exclusively on phenomena
that can be directly observed, leaving subjective or non-observable matters to
other disciplines.
What does the term inquiry mean in a scientific context?
✔✔ Inquiry is the systematic process of searching for and gathering
information.
What is the goal of discovery-based science?
✔✔ This approach involves documenting and describing natural structures
and patterns as a foundation for developing future hypotheses.
What are the requirements for a hypothesis-driven framework?
✔✔ This structure relies on posing specific questions and creating testable,
falsifiable predictions that can be investigated through experimentation.
How does a scientific theory differ from a simple guess?
✔✔ A scientific theory is broad in scope, consistently supported by a vast
body of experimental evidence, and serves as a tool for generating new,
specific hypotheses.
What is the biological definition of evolution?
, ✔✔ Evolution is the process of descent with modification, involving shifts in
the genetic makeup of a population over successive generations.
Adaptation -ANSWER✔✔a genetically inherited characteristic that enhances an
organisms ability to survive and reproduce
Biological fitness -ANSWER✔✔the contribution an organism makes to the gene
pool of the next generation, relative to the contribution of others
Artificial selection -ANSWER✔✔the intentional reproduction of individuals in a
population that have desirable traits
ex. Brassica oleracea, a wild mustard
Darwin's 4 Observations -ANSWER✔✔1. Members of a population often vary
greatly in their traits
2. Many of these traits are inherited from parents to offspring
3. Species are capable of producing more offspring than their environment can
support
4. Lack of these resources will prevent many of these offspring from surviving
Darwin's 2 Inferences -ANSWER✔✔1. Individuals whose inherited traits give
them a higher probability of surviving and reproducing in a given environment
tend to leave more offspring than other individuals
2. This unequal ability of individuals to survive and reproduce will lead to the
accumulation of favorable traits in the population over generations
Population -ANSWER✔✔a localized group of individuals that are capable of
interbreeding and producing fertile offspring
