IB 150 EXAM 1 UIUC EXAM QUESTIONS AND CORRECT
ANSWERS
1. Describe 2 distinct aspects of living organisms that set biotic (living):
need for
them apart from non-living objects: energy, ability to replicate (grow
reproduce
abiotic (living): no need for
energy, no ability to
grow (replicate) no
repro- duction
Organisms:
-are highly ordered
(non-random)
systems
-self replicate
-populations of organisms
adapt to their
organisms
-organisms grow and de-
velop
-organisms maintain a
controlled internal envi-
ronment (homeostasis)
-organisms react to their
