All the Extras
100
The group in an experiment that does not receive the treatment (or independent variable).
What is the control group?
100
Creates energy for the cell using its internal folded membrane
What is the mitochondria?
100
This nucleotide base pairs with Adenine.
What is Thymine?
100
Transport that requires energy.
What is active transport?
100
Double stranded nucleic acid.
What is DNA?
200
The variable that the scientist changes in an experiment.
What is the independent variable?
200
This structure best identifies a cell as being eukaryotic.
What is the nucleus?
200
This base pairs with Cytosine.
What is Guanine.
200
Transport that does not require energy.
What is passive transport?
200
Single stranded nucleic acid.
What is RNA?
300
What the scientist measures in an experiment.
What is the dependent variable?
300
This structure is found in both prokaryotic and eukaryotic cells and is responsible for producing proteins.
What are ribosomes?
300
DNA has complimentary strands that can be separated.
What is the reason DNA can easily replicate?
300
Moves from an area of high concentration to an area of low concentration.
What is diffusion.
300
Group of individuals that belong to the same species and live in the same area.
What is a population?
400
Only one variable.
What is the number of variables that are tested in an experiment?
400
This organelle creates energy for the cell and is thus called the "powerhouse" or power plant of the cell.
What is the mitochondria
400
DNA is a nucleic acid that forms a double helix.
What is the structure of DNA?
400
Moves agains the concentration gradient from an area of low concentration to an area of high concentration.
What is active transport?
400
Lack a membrane-bound nucleus and most other internal cell structures.
What are prokaryotes?
500
A testable question.
What is a hypothesis?
500
These three organelles have their own membrane.
What are mitochondria, chloroplasts, and nuclei?
500
mRNA
What is the product of DNA transcription?
500
Movement of water across a membrane.
What is osmosis?
500
Having many individuals in an experimental group.
What is having multiple trials?
