Organization of living systems begins with the...
cell; cells are made of molecules that contain atoms.
Cells combine to form a...
tissue (e.g., nervous tissue).
Different tissues combine to make up...
organs (e.g., the brain)
Organs work together as...
organ systems (e.g., the brain, spinal cord, etc.)
Each level of organization has...
emergent properties; however, all new properties follow the laws of
physics and chemistry.
Energy is capacity to do...
work; it takes work to maintain organization of the cell and organism.
Metabolism is all chemical reactions that occur in a...
cell.
Ultimate source of energy for nearly all life on earth is the...
sun through photosynthesis.
Organisms must remain homeostatic or keep themselves stable in...
temperature, moisture level,
acidity, etc. by physiology and behavior.
Multicellular organisms often unite...
sperm and egg, resulting in an immature individual which develops
to become the adult.
Genes are made of long molecules of...
DNA that specify how the organism is organized.
Adaptations are...
modifications that make an organism suited to its way of life.
Natural selection is...
process by which species become modified over time.
Evolution is...
descent with modification.
The fact that all life forms have DNA suggests...
all life has a common ancestor.
A population...
consists of all members of one species in a particular area.
A community...
consists of all of the local interacting populations.
An ecosystem...
includes all aspects of a living community and the physical environment, including
soils, atmosphere, etc.
Ecosystems are...
characterized by chemical cycling and energy flow.
Humans modify...
ecosystems for our own purposes.
Human beings depend on...
healthy working ecosystems for food, medicines, and raw materials.
Biodiversity consists of...
the total number of species, their variable genes, and their ecosystems.
Extinction is...
the death of a species or larger group; perhaps 400 species go extinct each day.
Preserving our biosphere helps..
ensure the survival of our species.
Taxonomy...
the Discipline of Identifying and Classifying Organisms
From larger categories to smaller:
kingdom, phylum, class, order, family, genus and species.
Biochemical evidence breaks life into three domains:
Bacteria, Archaea, and Eukarya.
The Archaea and Bacteria are not yet characterized into...
kingdoms.
Eukarya contains four kingdoms:
Protista, Fungi, Plantae, and Animalia.
A binomial is a two-part scientific name:
the genus and the specific epithet.
Scientific names are in...
latin.
Phenomena can therefore be understood from...
observations.
Inductive reasoning allows a person to...
combine isolated facts into a cohesive whole.
An experimental design is proposed that tests the...
hypothesis in a meaningful way.
Data are the results of...
experiments, and are observable and objective.
Often the data must be inspected for the probability the data could show a relationship by...
chance; this
is a measure of “significance.”
Whether the data support or reject the hypothesis is the basis for the...
"conclusion."
Science findings are reported in scientific journals so results are available to the...
Science findings are reported in scientific journals so results are available to the.
The ultimate goal is to understand the natural world in...
scientific theories, conceptual schemes
supported by a broad range of data.
The terms “principle” and “law” are also used...
for generally accepted theories.
The experimental variable is the step that is...
deliberately manipulated (nitrogen fertilizer).
A dependent variable is component of an experiment that...
changes due to the experimental
variable (yield).
