from an area of high concentration to an area of
low concentration.
What is Diffusion
100
Process by which a single species evolves into many new species to fill available niches.
What is Adaptive Radiation
100
The role of a species in its ecosystem, which
includes the way that the species interacts with the

cell divides.
What is Mitosis
200
Process of maintaining a stable environment inside a cell or an entire organism
What is Homeostasis
200
Organisms that have similar structures to organisms of other species because they
descend from the same ancestor.
What Homologous Structure
200
The study of how living organisms interact
with each other and their environment.
What is Ecology
200
A cluster of cells with similar functions.
What is Tissue

: Last stage of mitosis during which chromosomes uncoil to form chromatin, the spindle breaks
down, and new nuclear membranes form.
What is Telophase
300
The diffusion of water molecules across a
membrane

Organisms with more favorable traits are able to produce more offspring and pass on their
favorable traits.
What is Natural Selection
400
A model where evolutionary changes occur at a slow and steady pace.
What is Gradualism
400
An organism that breaks down the remains of producers and consumers and releases
simple inorganic molecules back into the environment. Can be classified as a scavenger, detritivore,
or saprotroph

Structure found in an organism that has no obvious use.
What is Vestigial Structure
500
An ecosystem is a complex system
that consists of all the biotic (living) and abiotic
(physical) aspects of the environment.
What is Ecosystem
