Scientific Method
The factor that is manipulated by the researchers and has an effect on the dependent variable
What is the Independent Variable?
The change of populations of species over time
What is Evolution?
Eukaryote cells are in this domain
What is Domain Eukarya?
DNA is kept in this organelle
What is the Nucleus?
The selective breeding of plants and animals by humans
What is Artificial Selection?
A scientific test in which an experimental group is compared with a control group
What is a Controlled Experiment?
Mechanism for evolution
What is Natural Selection?
Prokaryote cells are in these two domains
What are Domains Bacteria and Archaea?
This type of cell is smaller and simpler than Eukaryote cells
What is a Prokaryote Cell?
A map of evolutionary relatedness, like a family tree
What is Phylogeny or Phylogenetic Trees?
A proposed explanation for a set of observations which leads to predictions that can be tested by making additional observations or performing experiments
What is a Hypothesis?
When organisms who live in similar conditions evolve similar structures separately
What is Convergent Evolution?
Protists are in this domain
What is Domain Eukarya?
Animal and Plant cells are this type of cell
What is a Eukaryote Cell?
The expressed traits of an organism
What is Phenotype?
This variable also has an effect on the dependent variable
What is a Confounding Variable?
When organisms from the same common ancestor evolve and have similar structures but with different functions
What is Divergent Evolution?
These domains are everywhere
What are Domains Bacteria and Archaea?
Both types of cells contain this, though it is free-floating in one and in the nucleus in the other
What is DNA?
A random change in an organism's DNA which changes the organism's phenotype
What is a Mutation?
The variables in this group are the same, except for the independent variable; this group is compared to experimental group
What is a Control Group?
The feature of an organism that is a historical remnant of a structure that served a function in the organism’s ancestors; "leftovers" of evolution
What are Vestigial Structures?
Organisms in this domain are adapted to the most extreme environments
What is Domain Archaea?
This organelle uses DNA to produce proteins that cell needs to do its work
What are Ribosomes?
The genetic makeup of an organism
What is Genotype?
