IB 150 Exam 1 UIUC Questions With
Correct Answers
Describe |2 |distinct |aspects |of |living |organisms |that |set |them |apart |from |non-living |objects:
biotic |(living): |need |for |energy, |ability |to |replicate |(grow), |reproduce |
abiotic |(living): |no |need |for |energy, |no |ability |to |grow |(replicate) |no |reproduction
Organisms: |
-are |highly |ordered |(non-random) |systems
-self |replicate
-populations |of |organisms |adapt |to |their |organisms
-organisms |grow |and |develop
-organisms |maintain |a |controlled |internal |environment |(homeostasis)
-organisms |react |to |their |environment |
what |is |the |smallest |unit/level |that |we |recognize |as |"being |alive"?
cell
,Which |of |the |following |structures |is |only |associated |with |eukaryotic |cells?
mitochondria/other |organelles
DNA
nucleus |containing |the |DNA
cell |membrane
Mitochondria/other |organelles |+ |nucleus |containing |the |DNA
- |prokaryotes |:DON'T |have |any |membrane |enclosed |internal |organelles, |but |DO |have |DNA |to |
store |their |genetic |material, |and |an |external |membrane
The |core |properties |that |seem |to |set |life |apart |from |non-living |matter |can |be |organized |
according |to |2 |general |attributes:
(1)those |that |require |the |ability |to |pass |on |hereditary |(genetic) |information
and
(2) |those |that |require |the |input |of |energy |in |order |to |proceed
Try |to |categorize |each |of |the |following |properties |that |we |just |covered |with |respect |to |these |2
|attributes:
reproduction |and |growth:
evolution:
,maintaining |a |stable |internal |environment |that |is |different |from |the |external |environment |
(homeostasis):
reacting |to |the |environment:
reproduction |and |growth: |requires |BOTH |energy |input |and |hereditary |information
evolution: |requires |passing |on |hereditary |information
maintaining |a |stable |internal |environment |that |is |different |from |the |external |environment |
(homeostasis): |requires |energy |input
reacting |to |the |environment: |requires |energy |input
After |throwing |the |ball |in |the |air, |it |eventually |converted |the |gained |gravitational |PE |back |into |
kinetic |energy |as |it |fell |back |down. |What |happened |to |the |kinetic |energy |when |the |ball |comes
|a |halt |when |it |hits |the |table: |select |all |that |apply:
-The |energy |was |converted |into |sound |(kinetic |energy |associated |with |vibrations |of |air |
molecules)
-The |energy |was |converted |into |chemical |potential |energy
-The |energy |was |lost
-The |energy |was |converted |into |thermal |kinetic |energy |(it |heated |up |the |ball |and |table |surface
|during |the |impact |slightly)
-The |energy |was |converted |into |sound |(kinetic |energy |associated |with |vibrations |of |air |
molecules)
, -The |energy |was |converted |into |thermal |kinetic |energy |(it |heated |up |the |ball |and |table |surface
|during |the |impact |slightly)
Equilibrium |is |reached |when |the |water |(and |hence |salt) |concentration |on |both |sides |of |our |
semi-permeable |cell |membrane |is |equal, |and |maximum |entropy |(disorder) |is |achieved.
T |o |F:
When |equilibrium |is |reached, |water |molecules |stop |moving |across |the |semipermeable |
membrane.
false, |movement |continues, |just |the |rate |of |movement |of |water |molecules |across |the |
membrane |has |become |equal |in |both |directions
which |of |these |states |requires |only |exergonic |chemical |reactions?
a. |decaying |mouse
b. |living |mouse
decaying |mouse'
living: |requires |many |endergonic |processes |to |take |place
death: |results |from |an |inablity |to |engage |in |endergonic |processes |and |the |organism |decays |as |
its |macromolecules |fall |apart |into |constituent |parts |in |exergonic |reactions
