Scientific Method
This is an answer to a question which is testable.
What is a hypothesis?
The metric system is based on the powers of this number.
What 10?
All cells contain this barrier which selectively lets certain substances into and out of the cell.
What is a cell membrane/lipid bilayer?
This molecule carries genetic information for organisms.
What is DNA?
This scientist first discovered the principles of how species change over time.
Who is Charles Darwin?
This is the test of a hypothesis.
What is an experiment?
These are the three standard units in the metric sytem.
What are grams, liters, and meters?
This cellular organelle provides "energy" to the cell in the form of ATP.
What are mitochondria?
This scientist discovered the principles of inheritance, or how traits are passed from one generation to another.
Who is Gregor Mendel?
This is the process by which certain traits are 'selected' to be useful for helping an organism survive.
What is natural selection?
This is what scientists do after they have analyzed their data.
What is draw a conclusion?
Kilo means this many, in the metric system.
What is 1,000?
This is one of two structures that plant cells have which differ from what animal cells have.
What is either a chloroplast or cell wall?
This molecule carries the information from a gene to the outside of the nucleus.
What is mRNA?
This is what does the selection during the process of natural selection.
What is an environmental change?
This variable is what the researcher changes.
What is the independent variable?
The prefix centi- means this, in the metric system.
What is 1/100th?
Photosynthesis is carried out by this cellular organelle.
What is the chloroplast?
This is the base that adenine pairs with in RNA.
What is uracil/U?
This is the result for most species, eventually.
What is extinction?
This setup of an experiment is as close to natural conditions as possible.
What is the control setup?
One milliliter is equal to this many cubic centimeters.
What is one cubic centimeter (cc)?
This is the process by which molecules will move from areas of high concentration to areas of low concentration without additional energy being added.
What is diffusion?
This is the process that happens in the ribosome and results in a long chain of amino acids.
What is translation?
This happens when two populations that reproduce at different times of the year
What is temporal isolation?
