IB 150 uiuc exam 1 Questions With Complete Solutions
10*C rule Correct Answers for every increase in 10 degrees C,
the reaction doubles
10% rule Correct Answers 10% of the energy is transfered from
one level to the next
4 factors that determine population size and growth rate Correct
Answers population growth= (birthrate + immigration) -
(deathrate - emigration rate)
Abiotic Correct Answers non living
arteries Correct Answers take blood from heart
Autotroph Correct Answers producers, make own food
Biotic Correct Answers living
community Correct Answers 2 or more populations and their
enviorment
connection between 10% rule and 2nd law of thermodynamics
Correct Answers 10% of ingested energy stored in tissues is
used and lost
90% of energy is lost (2nd law- increase in disorder)
counter- current flow Correct Answers prevents organism from
reaching equilibrium, ensures difference in partial pressure so
that diffusion continues
, define terms b,d,r and K Correct Answers r-population growth
rate
K- carrying capacity
b- birth rate
d- death rate
density dependent Correct Answers limiting factor of a
population where in large, dense populations are more strongly
affected than small, less crowded ones
-death increases, birthrate decreases
density independent Correct Answers factor limiting the size of
a population whose effect is not dependent on the number of
individuals in the population
diffusion Correct Answers random movement toward state of
equilibrium
ectothermy Correct Answers heat from enviorment
endergonic reaction Correct Answers -reaction that absorbs free
energy from its surroundings
-deltaG is greater than 0
endothermy Correct Answers produce own heat
energy fluxes Correct Answers transfer of energy through
trophic levels
