Cards

Term
Define Evolution
Definition
the process of
change that transforms life

the change in the genetic material of a population of organisms from one eneration to the next
Term
Define Biology
Definition
the scientific study of
life
Term
Define emergent properties and give an example
Definition
Def: Something that from looking at it's lowest level composition, you cannot tell what i can become. sum of parts greater than whole

ex: DNA - looking at a couple of proteins you cannot tell it will be used for information
Term
Define Producers
Definition
Photosynthetic organisms that provide food to others
Term
Define Consumers
Definition
Ones that eat Plants or eat animals that benefit from plants
Term
Define Tropic levels
Definition
Levels of the food chain

Sunlight > Plants > (Chemical energy) > Animals > heat
Term
Define DNA and Gene
Definition
DNA is the genetic material of all cells
gene is a discrete unit of DNA
Term
Name some of the common properties all living things share
Definition
1. Order—the complex organization of living things
2. Regulation—an ability to maintain an internal environment consistent
with life
3. Growth and development—consistent growth and development
controlled by DNA
4. Energy processing—acquiring energy and transforming it to a form
useful for the organism
5. Response to the environment—an ability to respond to
environmental stimuli
6. Reproduction—the ability to perpetuate the species
7. Evolutionary adaptation—acquisition of traits that best suit the
organism to its environment
Term
Define prokaryotic
Definition
(no true nucleus), and most are unicellular and microscopic
ex: bacteria
Term
What are the three domains of life?
Definition

Bacteria—prokaryotic (no true nucleus), and most are unicellular and microscopic

Archaea—like bacteria, are prokaryotic, and most are unicellular and microscopic

Eukarya—are eukaryotic and contain a nucleus and organelles

Term
Define small-scale evolution
Definition
changes in
gene frequency in a population from
one generation to the next
Term
Define large-scale evolution
Definition
the descent of different species from
a common ancestor over many
generations.
Term
Define Discovery science
Definition
uses verifiable observations and measurements to describe science
Term
Define Hypothesis-based science
Definition
uses the data from discovery science to explain science

The hypothesis must be testable
The hypothesis must be falsifiable
Term
Whats the difference between a theory an hypothesis
Definition
a hypothesis is a proposed explanation for a set of observations

a theory is supported by a large and usually growing body of evidence
