Bio 1500 Unit 7 Exam
1. Describe the likely response of Andean hummingbirds to climate change: -
Since plants would go higher up, hummingbirds would go higher up
- Depending on their Hb aflnity type, they would either have an easy or hard time adjusting to higher altitudes
2. Predict which species of Andean hummingbirds have a higher/lower proba-
bility ofsurviving climate change.: Lower probability
-hummingbirds in high alts with preexisting high alt Hb
-hummingbirds in low alts with preexisting low alt Hb
Higher probability
-hummingbirds in low alts with intermediate alt Hb
3. Explain why Dr. Schul is studying katydids, even though he doesn't care
aboutkatydids: It helps him/his colleagues understand larger concepts of biology:
- the way traits/species evolve
- what genetic changes cause diversity
- how brains recognize sounds and patterns
1/8
,4. Explain why we are still talking about geese.: We are still talking about geese to help us
understand all the biological processes like selection, respiration, hemoglobin, etc.
5. Identify content and questions from our 'high altitude breathing unit' that
correspond todifferent levels of biological organization: 1) protein structure and function
-protein structure and folding
-Hb-O2 binding
2) genetics
-transcription/translation
-gene expression
-mutations/gene families
3) physiology
-bird/mammal respiratory system
-fetal development
4) ecology
2/8
, -climate change impacts
-Mt. Everest atmosphere
5) evolution
-phylogenetic trees
-speciation
-convergent evolution
6. Describe the structure of viruses: - Contain no cellular machinery, (no ribosomes/mitochondria,
etc.)
- Simplest: genetic material inside of a protein coat (capsid)
- Virion = viral particle
- Can't reproduce without help from a cell
7. Recall the features by which viruses are categorized: - Size and shape (helical, spherical,
head-tail)
- Genetic material (DNA/RNA, single vs double stranded, positive/negative sense, code for proteins that go into next
capside, or allow virus to use cellular machinery)
-Presence or absence of lipid envelope
8. Recall the general steps of viral reproduction: - the virus must attach to the surface of a cell
