Science
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
,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
,-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
, 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
grouping of units of something into levels of groups
real grouping
exists in nature
adaptive traits
compromises produced by competing selective pressures
adaption exist
in conflict with each other, one providing success in a situation and the
other is a detriment
when selection occurs in a population
-it preserves alleles that are successful under the prevailing environmental
conditions
when environment changes
adaptions fall behind, and an individual may look maladapted
adaptive changes in the morphology of species
