Question:
What is the term for a new species evolving from a common ancestor?
Answer:
Speciation
Question:

Mass Extinction Event
Question:

Question:
There are black and green snakes in a grassy field. A hawk feeds on these snakes. Which snake has the adaptation to survive?
Answer:
Green Snake
Question:
What is the definition of a species?
Answer:
Organisms with individal traits that breed/produce fertile offspring
Question:
When did most events of the geological timeline occur?
Answer:
Within the past 500 million years
Question:
What are the two sets of base pairs on a strand of DNA?
Answer:
A-T
C-G
Question:
What is a codon?
Answer:
3 RNA bases
Question:
What is the difference between a Base Inversion and Base Substitution Mutation?
Answer:
Inversion flips a sequence of codons. Substitution switches codons with incorrect base pairs.
Question:
What do we call structures in our bodies that we no longer use?
Answer:
Vesitigal Structures
Question:
Have scientists found a fossil for every old living organism? Why or Why Not?
Answer:
No. Must include one:
Some eroded away, some were eaten by predators, some were unable to be fossilized.
Question:
What is the DNA pairing for this sequence:
AATTGCTG
Answer:
TTAACGAC
Question:
Where does transcription occur?
Answer:
In the nucleus.
Question:
How do adaptations occur?
Answer:
Mutations
Question:
What descriptor splits are species in the phylogenetic tree?
Answer:
The species differ by their traits.
Question:
Define Faunal Succession
Answer:
Fossils in different geological layers can be used to determine the relative age of those layers
Question:
Where are Genes found in the body?
Answer:
On DNA strands in the 46 chromosomes that are found in every nucleus of our body's cells.
Question:
Where does translation occur and what does it produce?
Answer:
Ribosome and produces proteins.
Question:
What is a frameshift mutation? Is it severe or not severe?
Answer:
Frameshift is when one (or more) base pairs get added or subtracted. This changes the protein's amino acids from that point forward. VERY SEVERE
Question:
What is the difference between a homologous and analogous structure?
Answer:
Homologous = Same Parts, Different Function
Analogous = Different Parts = Same Function
