BIO 1500 - TEST 7 UPDATED Exam
Questions and CORRECT Answers
Describe the likely response of Andean hummingbirds to climate change. - CORRECT
ANSWER - -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. -
CORRECT ANSWER - -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. - CORRECT ANSWER - -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) - CORRECT
ANSWER - -protein folding
-HB-O2 bonding
Evolution (BIO-ORG/HIGH ALT BREATHING) - CORRECT ANSWER - -phylogenetic
trees
-speciation
-convergent evolution
, Genetics (BIO-ORG/HIGH ALT BREATHING) - CORRECT ANSWER --
transcription/translation
-gene expression
-mutations
Ecology (BIO-ORG/HIGH ALT BREATHING) - CORRECT ANSWER - -climate change
impacts
-everest atmosphere
Physiology (BIO-ORG/HIGH ALT BREATHING) - CORRECT ANSWER --
bird/mammal respiration
-fetal development
Describe the structure of viruses - CORRECT ANSWER - -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 - CORRECT ANSWER - 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
