Bio 1500 Mizzou Schul TEST 2 Exam Questions With
Correct Answers
/. Categorize different energy forms as 'kinetic' or 'potential' - Answer-Kinetic energy: the
energy of movement
□ Includes heat, light, electricity
Potential energy: stored energy
□ Includes chemical energy
□ You can store energy in chemical bonds
/.Apply the First Law of Thermodynamics - Answer-Energy is never created or
destroyed, but it can change form
/.Describe the mechanism of diffusion at the level of single particles - Answer-particles
move from high to low concentration
/.Describe the pattern observed due to diffusion and the level of many particles -
Answer-random
/.Explain how the behavior of single particles explains the observed pattern at the many
particles level - Answer-probability
/.Identify the wavelengths (i.e. colors) of light absorbed by chlorophyll - Answer-red,
blue and violet light
/.The main transport form and immediate source of energy in cells - Answer-ATP
/.Describe the chemical and energetic changes that occur as ADP cycles to ATP and
back again to ADP - Answer-E leaves ATP which makes ADP
/.Recall the processes that lead to the Great Oxygen Event & how earth looked before
and after this event - Answer-Cyanobacteria evolved photosynthesis which created O2
as a side effect which lead to Great Oxygen Event
Before: all organisms heterotrophic prokaryotes
After: Set the stage for geology and biology as we know it today
/.Assess the different outcomes of the great oxygen revolution regarding their
consequences for life on earth and for earth's geology and atmosphere. - Answer-
Minerals formed
□ Banded iron ore
Ozone layer formed
□ Protection from UV-light
Free O2 is toxic to cells
□ Led to global mass extinction
