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