Evolution
Organisms obey this rule: the organism best adapted to it's environment will survive and pass on its genetic code.
Natural Selection / Survival of the Fittest / Darwinism
Proteins
When the active site of the protein changes shape and can no longer bind to the substrate.
Denature
This means the macromolecule has both a hydrophilic and hydrophobic region.
Amphipathic / Amphiphilic
Powerhouse of the Cell
Mitochondria
The inherent trait which allows an organism to survive in an environment.
Selective Adaptation
Starch and Maltose are two examples of this macromolecule.
Carbohydrates
The area of a protein enzyme which binds to a substrate.
Active Site
Type of lipid which holds phospholipids together or apart.
Cholesterol
-BONUS Brownie POINTS!-
The character on my shirt yesterday.
Godzilla
The change in an environment that causes maladapted organisms to die, while the adapted individuals survive.
Selective Pressure
This is the building block of RNA and DNA
Nucleic Acids
These are the two chemical reactions which enzymes catalyze.
Hydrolysis / Dehydration Synthesis
Tonicity of the solution if the percent change in mass was positive.
Hypotonic
This is the organisms trophic level in a food web that consumes producers.
Primary Consumer
This diagram represents organisms ancestors and their increasing complexity of traits across time.
Phylogenetic Tree (not a Cladogram)
An error in DNA that causes a change to the proteins created.
Mutation
These are the three kinds of transportation. Mark which one uses ATP.
Diffusion, Facilitated Diffusion, and Active Transport *ATP
The amount of solute in the extracellular aqueous solution is higher than the cell and water moves out of the cell.
Hypertonic
This is a cellular structure that some bacteria have, but are not present in animal cells.
Cell Wall
The theory that organisms adapted during their lifetime and passed that trait down to their offspring.
Lamarckism
These three building blocks make up a nucleotide, together with A, T, C, and G compose DNA.
Phosphate, Carbohydrate (sugar), and Nitrogenous Base
An enzyme which functions best at 7pH is put into a 6pH solution and denatures. This is because the acidic pH was. . .
Outside Optimal Range
A flower is put into a vase of salt water. The flower droops and wilts. What is the tonicity of the flower cells compared to the salt water?
Hypotonic
A scientist wants to conduct an experiment on the effect of temperature on egg to hatching rates. What is the independent variable?
Temperature
