Biology 114 Final Questions and
Answers...
✓ ~~~process of identifying patterns and asking questions, helps us to understand patterns
through asking questions
hypothesis
✓ ~~~theory that is specific, testable and can produce rejectable statements in an attempt to
answer a question
theory
✓ ~~~umbrella like concept of hypothesis, in science it needs a tremendous amount of
evidence supporting the concept and patterns it describes
pattern
✓ ~~~refers to the general observations of repetition one sees within a syste,
process
✓ ~~~mechanism, or way in which the pattern occurs
proximate
✓ ~~~refers to that which occurs in the short term
ultimate
✓ ~~~refers to a longer timeframe
cell theory
, ✓ ~~~all organisms are made of cells and contain chemicals, and all cells come from
preexisting cells
cell
✓ ~~~a naturally occurring compartment bounded by a thin, flexible, membrane and
contains chemicals in an aqueous solution that perform life functions
life is continuous
✓ ~~~60 trillion cells that make up the body came from a single celled fertilized egg. the
zygote came from the fusion of your parents gametes
evolutionary theory
✓ ~~~all life as we know it is the product of evolutionary processes, if certain heritable traits
help individuals produce more offspring, then those traits become more common n the
population over time
evolution explains
✓ ~~~variation, how it came about and what can happen if environmental conditions change
all species are
✓ ~~~related to each other through common ancestry
natural selection
✓ ~~~-process by which individuals possess alleles selected for and some against, leads to
a decrease of allele frequency due to random events
Biological Hierarchy
✓ ~~~framework of organization regarding all life around us, it provides us with a simple
way of guaranteeing we are talking about the same terms as we consider life across
varying scales
,hierarchy is important
✓ ~~~to distinguish between populations and individuals
organisms
✓ ~~~-individuals
-collection of organ systems
organismal approach
✓ ~~~concerned with how the organism behaves, its place in its population, community, etc
and how it survives as a result of its behaviors physiology
populations
✓ ~~~collections of individuals of the same species, typically interbreeding
population biologists
✓ ~~~concerned with population growth and evolutionary processes and other changes
through time
communities
✓ ~~~a collection of populations of different species living together in the same area
community biologists
✓ ~~~-concerned with diversity of species and relationships each species has with other
systems
ecosystem
, ✓ ~~~communities plus their abiotic factors
ecosystem synonym
✓ ~~~biomes
biomes
✓ ~~~refers to a collection of very similar ecosystems, largely bounded by global influences
like weather and climate
biosphere
✓ ~~~-all the ecosystems put together
-all that gets in is sunlight and all that leaves is heat energy
biosphere scientists
✓ ~~~concerned with climate change and other global issues
key points on hierarchy
✓ ~~~-similarity between individuals within each level, with respect to structural and
functional complexity
-units of each level defines the next level
emergent property
✓ ~~~the collection of the units as 1 level takes on a trait that is greater than the sum of its
parts
hierarchy
