What is the if then logic statement?
Deductive Reasoning
What are the two parts of an experiment? definitions.
Experimental: only independant variable changes
Control: everything kept normal; used to compare to experimental group
Are Hypotheses proven?
Only proven false, only supported true
What are the three domains of life? Definitions
Bacteria(Prokaryotes-Lack nucleus and organelles),
Archaea(Prokaryotes but are extremophiles),
and Eukarya(Nucleus, organs, multicellular)
What are the five kingdoms and what domains are they in?
Bacteria, Eubacteria(Bacteria)
Archaebacteria(Archaea)
Protista, Animalia, Fungi, and Plantae(Eukarya)
Define Protista
Dont fit anywhere else, singular+Multicellular, autotrophs and heterotrophs
Define Plantae
Autotrophs, Multicellular, cell walls of cellulose
Define Animalia
Heterotrophic, Multicellular, lack rigid cell walls, most can move(motile) at some point in life
Define Fungi
Heterotrophic by absorption, cell walls made of chitin, multicellular. Ex>Molds, yeasts, mushrooms

Name and define the Properties of life
Order: Organisms are organized systems
Regulation: Regulate internal enviorment
Growth and Developement: Grow in size and more, Develope; cells change into different types.
Energy Utilization: Take in energy and transform it; metabolism
Response to Enviorment: stimuli appropriately, sweat when hot, shiver when cold.
Reproduction: asexually or sexually
Evolution: species evolve over time
What is the smallest unit that can perform all living functions?
A Cell
In order for natural selection to happen…
- ) A pop needs to consist of breeding individuals with varied heritable traits
- ) Elimination of individuals with certain traits
- ) Reproduction of Survivors
