Biomolecules
These are the four classes of biomolecules.
What are proteins, lipids, carbohydrates and nucleic acids?
What is an electron?
Enzymes made of this biomolecule.
What are proteins.
This occurs randomly allowing species to evolve over time.
What is genetic mutation?
This variable is what is being measured in an experiment.
What is a dependent variable?
This biomolecule includes sugars, starches, glycogen, fibers, and chitin.
What are carbohydrates?
An aqueous solution with more H+ ions than OH- ions.
What is an acid?
This is where the substrate binds.
The scientist who came up with the idea of natural selection.
Who is Charles Darwin?
This type of graph is used to track data over a period of time.
What is a line graph?
This biomolecule is made up of amino acids and peptide bonds.
What are proteins.
These molecules have the same chemical formula but form different structures.
What are structural isomers?
The specific molecule(s) that an enzyme binds to.
What are substrates.
This occurs when unrelated species evolve similar traits over time to deal with similar environmental pressures.
What is convergent evolution?
The system of measurements used in a scientific setting.
What is the metric system?
This biomolecule is composed of a ribose sugar, a phosphate group and nitrogenous base.
What are nucleic acids?
The attraction between a partially positive hydrogen and a partially negative fluorine, oxygen, or nitrogen.
What is a hydrogen bond?
Enzymes speed up reactions by lowering this.
What is activation energy?
This happens when certain individuals in a given population survive longer and reproduce more due to having better adaptive traits.
What is differential reproduction?
These outside variables should be accounted for to ensure a valid experiment.
What are confounding variables?
What are lipids?
This functional group contains one oxygen and one hydrogen.
What is a hydroxyl group?
This type of molecule decreases enzyme activity by blocking or changing the active site.
What is an inhibitor.
This occurs when humans interfere with the reproduction of plants and animals.
What is artificial selection?
This is what an experiment is testing.
What is a hypothesis?
