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

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
O2 reacted with Methane (greenhouse gas), removing it from the atmosphere
□ Led to snowball ice age (2.4-2.1 bya)
Some prokaryotes evolved ways to use O2
□ Leading to evolution of cellular respiration
(later) Eukaryotes with chloroplasts
□ More effective photosynthesis
□ Even higher O2 levels
□ (much later) Evolution of multicellular life
Generated new niches
□ opportunities to diversify
Describe the relationships between the terms chromosome, gene, allele, and DNA. -
answer✔✔Gene: a segment of DNA with instructions for building a protein
□Specifies the sequence of amino acids that make up the protein
Alleles: different possible forms of the same gene
□ Differ in DNA sequence and therefore in protein structure they code for
□ There may be many different alleles of the same gene
□Any one person can max. of two different alleles
• Because of two copies of chromosomes
Describe the difference between the various alleles of a gene. - answer✔✔Alleles differ in DNA
sequence than genes
