Evolution
Define natural selection
Organisms that have specific traits which are more suited to the environment around them are more likely to survive and prosper than those who lack given traits.
What group is a part of every amino acid?
The R group
Name the four main classes of biomolecules.
Carbohydrates, lipids, proteins, and nucleic acids
What is the purpose of experiments?
What is the value of the base unit within the metric system?
1
What is a mutation?
A change within DNA that can affect physical traits and/or appearances.
How many different amino acids are there in proteins?
20
What is Benedict's reagent used for?
To detect the presence of monosaccharides
What is an independent variable?
A variable within an experiment that is not changed or altered.
How many grams are in a kilogram?
1,000
Are mutations beneficial or harmful to an organism?
Depending on the environment the organism lives in, the mutation could either help or hurt the organism.
Is Alanine a polar or non-polar amino acid?
Non-polar
Is water a positive or negative control?
Negative
What is a dependent variable?
A variable within an experiment that is changed or altered in order to see what effects take place.
How many millimeters will it take to get 1 centimeter?

Define artificial selection
Artificial selection is when humans choose traits within animals or plants that will benefit themselves. They continue to develop these traits with future plants and animals they decide to keep, while ignoring the plants and animals who lack these traits.
What is located in the R group of Glycine?
One hydrogen atom
What biomolecule is being looked for when using Sudan III?
Fats
What graph would be best to use for data that is recorded over a period of time?
Line graph
What is the scientific notation for the prefix deka?
10^1
Would a mutation that allows a bird to blend in better with the environment be considered natural or artificial selection?
Natural selection
Name the following amino acid based on the atoms in its R group: CH2, OH
Serine
If a solution changes to the color dark blue, what biomolecule is present in the solution?
Polysaccharides
What are controlled variables? Why are they important to look out for?
Variables that have the ability to alter the dependent variable. These variables are important to look out for because they could affect the dependent variable in ways that will lead to false conclusions in an experiment.
What is the scientific notation for the prefix tera?
10^12
