A polar bear's white fur allows it to be camouflaged while hunting in a snow covered area.
What is an example of an adaptation?
200
Tissues in a multicellular organism work together in this level or organization.
What is an organ?
200
The process when stem cells change into specialized cells.
What is differentiation?
200
An outer barrier of ALL types of cells, that only allows certain things in or out.
What is the cell membrane?
300
Something the experimenter changes in the experiment.
What is the Independent Variable?

When one parent cell gives rise to two cells.
What is asexual reproduction?
300
A type of nucleic acid that is the primary storage unit for cellular information.
What is DNA?
300
Type of stem cells that can be created out of normal body cells.
What are IPS (Induced pluripotent stem cells)?
300
Little cell factories that make proteins.
What are ribosomes?
400
This allows someone to replicate the experiment.
What is the procedure?
400
This type of organism makes its own food from sunlight.
What is an autotroph?
400
The specific reason DNA segments are different in different people.
What is the pattern of DNA units?
400
signals that tell stem cells what to change into.
What are growth factors?
400
A vesicle with enzymes in it that break down cellular waste.
What is a lysosome?
500
This ensures the experimenter what has caused the results.

500
The reason my internal temperature should always be 98.6 degrees, even when it is -20 degrees outside.
What is homeostasis?
500
When an egg is used, its DNA is replaced with the DNA of another cell, and then the cell is watched as it grows.
What is nuclear transfer or cloning?
500
A simple cell with no nucleus or fancy organelles like plant and animal cells.
