Who started studying two stains of a virus?
Griffith in 1928
100
Sharp teeth, because they were made for defense.
Which of the following is an adaptation: the sharp teeth or scar on ear?
100
Because their offspring (mule) is infertile.
Why are donkeys and horses considered species?
100
Radial symmetry
What are two characteristics common to all cnidarians?
100
They are a branch of the vertebrate clade including reptiles, birds and mammals
What are Amniotes?
200
When he mixed the 2 strains and the heat treated strain 1 was deadly to the mice that was a surprise.
How did Griffith's experiments indicate the presence of a "transforming factor" in bacteria?
200
Similar structure in more than 1 species but on common ancestor.
What are homologous structures?
200
Dramatic Biological changes evident in fossil record
What is macroevelution?
200
Hydra: cylindrical body, tentacles from one end Marine Jelly: umbrella- shaped, tentacles around the lower edge.
Describe the difference in body structure between a hydra and a marine jelly.
200
Amniotic egg Internal fertilization water-tight skin
What are 3 distinctive features of amniotes?
300
he showed that transforming factor was more likely to be DNA then protein.
What did avery's experiment add to the knowledge gained from griffith's experiment?
300
The bugs create a resistance to the pesticide.
Why does specific pesticide become less effective over time?
300
Because it causes gradual adaptation through natural selection
How does punctuated equilibrium relate to darwin's theory of nature selection?
300
Turbellians- planarians Termatoda- Flukes Cestoidea- Tape worm
List 3 flatworm classes and give an example of each.
300
they are hard overlapping layers of keratin
What are scales?
400
each strand acts as a template, complementary bases link up across from each existing strand, creating two new daughter strands
Describe how DNA replicates by using a template.
400
Low variation in the gene pool that means that cheetahs decrease.
How has genetic drift affected the world's population of cheetah?
400
Flippers in penguins that are used in swimming are actually modified wings.
Give an example of evolutionary remolding of an existing structure to a new function.
400
class polychaeta, class oliogochatea, class hirudenea
What are three classes of annelids?
400
Flying style Beak and foot adaptation behavior
What is some diversity of birds?
500
DNA is replicated before a cell divides and in preparation for reproduction.
Under what circumstances is DNA replicated?
500
Natural selection and Genetic Drift
What are 2 main forces of revolutionary change in gene pools?
500
Ending the growth sooner in development
Identify 1 possible even during an organism's embryonic development that can result in a change in body form
500
Locomotion, feeding, and respiration
Describe the function of the water vascular system of echinoderms
500
220 million years.
How old are the oldest fossils?
