What is Uracil?
How cells can send signals to cells in other parts of the body
What is endocrine signaling?
Contains a single, circular chromosome
What is prokaryotic DNA?
What are keystone species?
This process of cellular respiration occurs in both prokaryotes and eukaryotes in the cell cytosol
What is Glycolysis?

The process shown above
What is dehydration synthesis?

The effect that a change from a moderately acidic environment (pH near 6) to a basic environment will have on peroxidase activity
What is a decrease in peroxidase activity?
Relieves tension in the overwound DNA of a replication fork
What is Topoisomerase?
A sequence of unlearned acts directly linked to a stimulus
What are fixed actions patterns (FAPs)?
These nucleotide bases are pyrimidines
What is Cytosine, Uracil, Thymine (CUT)
Supports the claim that mitochondria evolved from once-free-living prokaryotic cells by the process of endocytosis
What is the mitochondria's double membrane?
Where the Krebs Cycle occurs
What is the mitochondrial matrix?
This method separates DNA fragments by size
What is Gel Electrophoresis?
A response to a stimulus becomes the next stimulus for a behavior
What are stimulus response chains?
The leading strand of DNA during replication moves in the __ direction, whereas the lagging strand moves in the __ direction
What is 5' to 3' ; 3' to 5'?
A unique characteristic of saturated fatty acids
What are single bonds between carbon atoms?
Molecule that relays messages from receptors to other molecules only inside the cell
What is a secondary messenger?
These two scientists discovered that the semi-conservative model of DNA replication is correct
Who are Meselson and Stahl?
Evolution occurs rapidly after a period of stasis
What is punctuated equilibrium?
The hybrid offspring of the first generation may be fertile, but the offspring of the second generation are sterile
What is hybrid breakdown?
Ions move down their concentration gradient across the membrane.
What is facilitated diffusion?
Why carrier molecules that transport electrons in the ETC are found within membranes
What is energy derived from the ETC creating a difference in the concentration of protons on either side of the membrane?
These are the three sites within a ribosome
What are the amino acid, polypeptide, and exit site?
This assumes that the population is not evolving; if differences exist between expected and observed data, the population of a species may be evolving
What is Hardy-Weinberg Equilibrium?
These are the three amino acid codon combinations which are stop codons
What are UAA, UAG, and UGA?
