STUDY
PLAY
Eukarya
Humans belong to the domain __________
Controlled Experiment
Has one variable
Data
Measurements collected over a certain amount of time
Qualitative
Type of data, descriptive
Quantitative
Type of data, number
Theory
The best explanation that is supported by lots and lots of data
Ecology
Study of the interactions among organisms and between organisms and their environment
Niche
A species' unique way of living
Limiting Factors
Conditions that restrict a population's growth
Carrying Capacity
Number of organisms in a population that the environment can maintain with no net increase or decrease
Predation
An interaction in which one organism eats another
Parasitism
Relationship in which one organism (parasite) obtains its food at the expense of a host
Mutualism
Both organisms benefit from the symbiotic relationship
Commensalism
One organism benefits, while the other is unaffected
Ecological Succession
Species are replaced as other species move into the area later
Imprinting
Formation of a bond between two animals, usually a parent and a newborn
Circadian Rhythm
Instinctive behavior that occurs usually every 24 hours
Migration
Innate behavior of returning to a birth place or nesting place
Innate Behavior
Behavior that an organism is born knowing how to do
Learning
A change in an organisms behavior based on experience
Habituation
When an organism becomes so used to a stimulus, it no longer responds
Classical Conditioning
An organism responds to a stimulus based on a reward or punishment
Insight
Responding appropriately to a situation without having previous experience in that situation
Territorial Behavior
Behavior an organism uses to mark its area
Communication
Signaling between organisms
Proton
Located in the nucleus, has a positive charge
Neutron
Located in the nucleus, has no charge (neutral)
Electron
Located outside of the nucleus, has a negative charge
Enzymes
Main catalysts of chemical reactions in organisms (special proteins)
Nucleus
Stores DNA and controls activities of the cell
Lysosome
Breaks down macromolecules into smaller particles
Prokaryotic
Simple, small cell that lacks organelles
Microfilaments
Responsible for cell movement
Active Transport
Movement of molecules that requires energy - goes from low to high concentration
Eukaryotic
Type of cell that is highly organized with organelles
Cell Membrane
Controls what enters and exits cell, made of lipid bi-layer
Diffusion
Molecules moving from high to low concentration
Chloroplast
Sunlight is converted to sugar here
Ribosome
Proteins are made here
Cell Wall
Found in plant, not animal cells
Osmosis
Water moving from high to low concentration
Endoplasmic Reticulum
Transports materials around the cell
Autotrophs
Organisms that make their own food using sunlight
Consumers
Organisms that must obtain their energy from food
Sugar + O2 = CO2 + H2O + Energy

Cytokinesis and Mitosis
Two main stages of the Mitotic Phase
Gametes
Produced by Meiosis
Cytokinesis
A cell splits into two daughter cells during ______________
Homologous Chromosomes
Two sets of chromosomes found in a body cell, one set inherited from the male parent, and the other from the female parent
10
A cell that has 5 chromosomes in the G1 phase will have ____ chromatids in the G2 phase
