BIO 1500 - TEST 7 QUESTIONS AND
ANSWERS 100% PASS
Describe the likely response of Andean hummingbirds to climate change. - ✔✔-species
with high-alt HB become more favorable, species with low-alt HB become least
favorable
-species migrate to higher elevations as sea level temperature increases
-random mutations or displacement to similar elevations with colder temps is the only
way for low-alt HB species to survive
-as low-alt HB species die off or are displaced, there is less competition for direct
resources for high-alt HB (increases survival)
Explain why Dr. Schul is studying katydids, even though he doesn't care about
katydids. - ✔✔-provides info about other species (SPECIFICALLY HOW THEY
EVOLVE & WHAT DRIVING FACTORS INFLUENCE SPECIATION)
-able to draw conclusions from easily
-helps to understand research questions that are essential to basic biology

,Explain why we are still talking about geese. - ✔✔-provides framework to discuss
biological concepts in a context
-easy to make connections across units (protein biology/synthesis, evolution by natural
selection, phylogenetic, genetics/mutations, respiratory systems)
Protein structure & function (BIO-ORG/HIGH ALT BREATHING) - ✔✔-protein
folding
-HB-O2 bonding
Evolution (BIO-ORG/HIGH ALT BREATHING) - ✔✔-phylogenetic trees
-speciation
-convergent evolution
Genetics (BIO-ORG/HIGH ALT BREATHING) - ✔✔-transcription/translation
-gene expression
-mutations
Ecology (BIO-ORG/HIGH ALT BREATHING) - ✔✔-climate change impacts
-everest atmosphere
Physiology (BIO-ORG/HIGH ALT BREATHING) - ✔✔-bird/mammal respiration
-fetal development

, Describe the structure of viruses - ✔✔-no cellular machinery
-no organelles
-simplest viruses = genetic material (DNA or RNA) in protein coat (capsid)
-cannot reproduce without host cell; must invade host cell & use that cell's machinery to
actually reproduce
Recall the features by which viruses are categorized - ✔✔size & shape of capsid
1. helical = long & thin
2. spherical = not perfectly round, resembles circle/oval
3. head-tail = most complex, can invade bacteria cell
genetic material
-DNA or RNA
-single or double stranded
-positive sense (read directly) or negative sense (has to be translated)
presence or absence of envelope (lipid bilayer around capsid)
Recall the general steps of viral reproduction - ✔✔1. attachment to surface of cell
