BIO 1500 FINAL EXAM
1. dragonflies as formidable aerial and aquatic predators: aerial: adults catch flying insects
mid flight; aquatic: larvae are fearsome predators
2. describe the life changes of dragonflies: - live for 3+ years in the water (aquatic larvae)
- larvae have labium with claws at the end of it
- exoskeleton cracks and dragonfly emerges
3. identify dragonflies as ancient insects (when, what, why): - known as Meganeura (as
fossils)
- first fossils date to 325 mya
- among the first insects to fly
- exhibit a "primitive" wing morphology
- 3 ft wingspan; 150g
4. identify the outstanding characteristic of animals (including dragonflies) in
the carboniferous: huge body size
5. compare dragonfly size from ancient times to today: - ancient: 3ft wingspan; 150g
- today: <6in wingspan; 1g
,6. develop more than one hypothesis for why dragonflies were so big: - O2 levels
- environment
- predators/prey
- carbon levels
7. Identify the most important and least important attribute for employers and
medical schools:
a) team-working skills
b) content knowledge
c) communication skills
d) learning skills: most important: team-working skills
least important: communication skills
8. recognize how the relatively small contribution of each individual test will
contribute to your final class grade: tests are 35% as a whole; each test equals 5% of the final grade
,9. recognize how the importance of the final exam as an opportunity to improve
will contribute to your final class grade: the final exam is 15% of the final grade, so you can do really
well to make up from poor grades on previous tests
, 10. recognize how lab and discussion scores are combined for the "lab/Discus-
sion" part of the
final grade: the total lab and discussion grades will be multiplied to get your combined lab/discussion grade
11. recognize why unexcused absences in discussions will significantly reduce
your overall grade: discussion is based solely on participation and preparation. it's combined with lab (which
makes up 25% of the final grade) and unexcused absences will hurt the overall grade
12. when was the universe formed/big bang?: 13.7 billion years ago
13. when was earth formed?: 4.6 billion years ago
14. when was the moon formed?: 4.5 billion years ago
15. when were the oldest rocks formed?: 3.8-4 billion years ago
16. when were the oldest fossils (=signs of life) formed?: 3.5-3.8 billion years ago
