bio 1500 final exam comprehensive
Questions and Answers with Verified
Solutions
Question 1:
Recognize dragonflies as formidable aerial and aquatic predators
Answer:
-large, powerful, intense -operating in air -aquatic larvae
Question 2:
when: Carboniferous Period (360-300 mya) what: among the first insects
to fly why: first fossils: 325 mya
Answer:
Identify dragonflies as ancient insects (when, what, why)
Question 3:
Identify huge body size as the outstanding characteristic of animals
(including dragonflies) in the carboniferous
Answer:
-Dragonflies had a wingspan of 3 feet and weighed 150 grams
-Environmental factors (oxygen, carbon, temperature) -High energy
demands, natural selection, and prey
Question 4:
Describe the life stages of dragonflies
Answer:
egg, larvae, adult dragonfly
,Question 5:
Develop more than one hypothesis for why dragonflies were so big
Answer:
-The carboniferous period provided them more oxygen causing them to
be larger in size -Different prey were around during the period that
caused them to be larger in size
Question 6:
Evaluate these hypotheses based on your explorations in EarthViewer
Answer:
Oxygen concentration, larger size made them better predators, aerial
predation was more prevalent during this time, so they needed to be
larger in order to survive.
Question 7:
Identify the most important and least important attribute: team-working
skills,content knowledge, communication skills, learning skills, etc. ... for
employers and medical schools
Answer:
Most important- team working skills Least important- knowledge of job
Question 8:
Recognize how the different compo-
Answer:
nents of the course contribute to your final class grade, in particularthe
relatively small contribution of each individual test- the importance of the
final exam as an opportunity to improve- how lab and discussion scores
are combined for the "lab/Discussion" part of the final grade- why
unexcused absences in discussions will significantly reduce your overall
grade

indicated in the online learning module.
Answer:
Earth formed 4.6 bya oldest rock 3.8 bya oldest fossils/signs of life 3.5
bya cyanobacteria 2500 mya aglae 1200 mya cambrian explosion 545
mya first dinosaurs 230 mya first birds 150 mya dinosaur extinction 65
mya modern humans 200,000 ya
Question 10:
Relate the Carboniferous to the big picture of the history of life on earth:
when was it?
Answer:
-The Carboniferous period happened recently when looked at in the big
picture of the history of time -Although life began relatively soon after the
earth cooled, most major evolutionary changes occurred in the most
recent fifth of earth's history
Question 11:
Identify interesting and 'unusual' events in the history of earth
Answer:
"snowball" ice age
Question 12:
Recall environmental characteristics of the Carboniferous time
Answer:
