Scientific Thinking
This is the first step in the scientific method.
asking a question (or making an observation)
This kingdom includes bacteria that live in extreme environments.
Archaea
The tissue that carries sugars made in photosynthesis.
Phloem
Animals without backbones.
Invertebrates
A permanent change in a DNA sequence.
Mutation
A testable explanation for a scientific question.
Hypothesis
A single-celled eukaryote often called a “misfit” in classification.
Protist
The process by which water moves upward in plants due to evaporation.
Transpiration
The flexible support rod found in all chordates at some point.
Notochord
A change in one single base pair of DNA.
Point Mutation
This type of data includes numbers and measurements.
Quantitative data
Microbes that break down dead organisms.
Decomposers
This group of plants does not have true roots, stems, or leaves.
Nonvascular Plants (bryophytes)
A protective flap that covers the gills in bony fish.
Operculum
The part of the bacterial genome that controls multiple genes together.
Operon
In an experiment, the factor that is changed by the scientist.
Independent Variable
The movement structure used by a paramecium.
Cilia
The dominant generation in mosses.
Gametophyte
Animals with four limbs or descended from four-limbed ancestors.
Tetrapods
The purpose of gene regulation in cells.
to turn genes on or off as needed (conserve energy)
The group in an experiment that does not receive the independent variable.
The Control Group
A relationship where algae live inside coral, providing it with energy.
Symbiosis (Mutualism)
These seed plants do not produce flowers or fruits.
Gymnosperms
The outer body covering found in insects and crustaceans.
Ecoskeleton
This type of mutation adds or deletes a base, shifting the reading frame.
Frameshift Mutation
