BSCI 207 EXAM 1 QUESTIONS AND VERIFIED
ANSWER; 100% CORRECT; 2026- 2027 UPDATE
2 Types of homologous traits - correct answer-
Plesiomorphic - primitive (ignored as well as convergent)
Apomorphic - derived
Allometric - correct answer- Organisms rarely exhibit
isometry, rather allometry where shape changes as size changes.
Allows to reach larger size and new combinations of properties
Aperiodic - correct answer- Genetic material is an
"aperiodic crystal"
Bioenergetics - correct answer- Molecular mechanisms
for extracting & manipulating energy to maintain internal order
Clade - correct answer- Group of species united by
synapomorphies ( = shared derived traits)
Common Slopes - correct answer- Isometry - 1/3
Area/Volume Allometric ~ 1/3
, Most scaling in organisms have slopes of 1/4
Complex Transport Systems (Metabolism) - 3/4
Control Center - correct answer- Compares information
from receptor with set point & determines counteraction
Convergent Similarity - correct answer- Independent
origins, Analogous structures. i.e., wings in birds & bats
Not very informative
Derived Similarity - correct answer- Single origin in
relatively recent common ancestor, homologous structures,
informative
DNA - correct answer- More stable; unable to catalyze
reactions; proteins required for information transfer
Effector - correct answer- Uses information from control
center to affect regulated factor
