What are "existing cells"?
100
This organelle houses the DNA in eukaryotes.
What is the nucleus?
100
This evolutionary force always leads to a better-adapted population.
What is natural selection?
200
Every organism is made up of one or more of these small packages, containing all the molecules necessary for life.
What is a cell?
200
This scientific field studies carbon-containing compounds.
What is organic chemistry?
200
This type of cell has no membrane-enclosed organelles.
What is a prokaryote?
200
This organelle produces ATP to power the cell.
What is the mitochondrion?
200
The major flaw in Lamarck's theory was that he believed this kind of traits is passed down from parent to offspring.
What is an acquired trait?
300
A blowfly, which eats dead animals and digests them internally in its stomach, is an example of this type of energy-obtainer.
What is a consumer?
300
These six elements (types of atoms) are necessary for all organisms.
What are carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur?
300
In prokaryotes, DNA is stored here.
What is the nucleoid region?
300
The centriole, which aids cell division, is found only in this type of cell.
What is the animal cell?
300
This evolutionary force is the source of different versions of the same gene.
What is mutation?
400
When a multicellular organism's cells divide, it is an example of this characteristic of life.
What is "growth and development"?
400
This carbohydrate is used by animals to store energy.
What is glycogen?
400
This type of eukaryotic cell has a cell wall and contains chloroplasts.
What is a plant cell?
400
This organelle is where proteins go after the rough endoplasmic reticulum if they are headed out of the cell.
What is the Golgi apparatus?
400
This is the final step of speciation.
What is division, in which members of the two new species can no longer successfully reproduce?
500
Viruses display only these two characteristics of living things.

What are "polypeptide" and "amino acids"?
500
These three structures are shared by all cells.
What are the cell membrane, DNA, and ribosomes?
500
These three organelles are found in plant cells, but NOT in animal cells.
What are the cell wall, large central vacuole, and chloroplasts?
500
Natural selection happens to the _____________, but evolutionary change happens to the ______________.
What are "individual" and "population"?
