1. Archaeopteryxlithographica, considered to be the first bird capable ofpowered flight, is thought
to have evolved from within all ofthe following traditional reptilian groups except:
A. superorder Dinosauria
B. subclass Diapsida
C. suborder Theropoda
D. order Saurischia
E. order Ornithischia
2. During photosynthesis, greensulfur bacteria can use either sunlight, or dim red light fromvolcanos, to consume electrons and hydrogen atoms from which of thefollowing inorganic substrate molecules?
A. hydrogen sulfide
B. glucose
C. elemental sulfur
D. water
E. carbon dioxide
3. The dominant terrestrial predators during the CretaceousPeriod (towards the end of the late Mesozoic Era) werecharacterized by all of the following traits except:
A. a partial four-chambered heart with an incompleteinterventricular septum
B. two pairs of post-orbital fenestrae in the skull
C. jaw muscles attached to an extendable mandible
D. reproduction by means of an amniote egg
E. one pair of post-orbital fenestrae in the skull
4. Which of the following mutationsis categorized as a micromutation, because it involves only onenucleotide substitution (which is typically non-synonymous)?
A. a chromosomal translocation
B. a chromosomal deletion
C. a chromosomal duplication
D. a transversion mutation
E. a chromosomal inversion
