●● the most widely accepted characteristics of an organism
Answer: (1) Order, (2) Evolutionary Adaptation, (3) Regulation, (4)
Energy Processing, (5) Growth and Development, (6) Response to the
Environment, and (7) Reproduction
●● Order
Answer: structures are comprised of the basic unit of life which is the
cell
●● Life is structured into a developmental hierarchy whereby cells give
rise
Answer: rise to tissues, tissues to organs, and organs to whole organ
systems
●● Evolutionary adaption
Answer: often called generational evolution, specifically refers to
smaller, genetic changes that allow for better survival of an organism.
For instance, consider camouflage
,●● Regulation
Answer: Living organisms are sensitive to temperature, environmental
stresses, pH requirements etc. and go to great lengths to ensure optimal
levels are maintained. include shivering to generate body heat in humans
or the regulation of blood flow through an organism.
●● Energy Processing
Answer: In order to sustain life, biochemical reactions are utilized. The
sum of these biochemical reactions is referred to as metabolism
●● Growth and Development
Answer: Perhaps intuitive, a living thing grows, matures, ages, and
experiences death.
●● Response to the Environment
Answer: Living things respond through adaption. An adaption is a
change or a process that allows an organism to become better suited for
their environment
●● stimulus
Answer: Anything that causes an organism to respond
●● Reproduction
, Answer: living things must have a way of producing new and thriving
generations to replace the previous ones.
●● Sexual reproduction
Answer: involves the fusion of two gametes (one from each parent) that
will unite and grow into a new offspring
●● Asexual reproduction
Answer: gives rise to new offspring from a single organism
●● Levels of Biological Organization
Answer: biosphere, ecosystems, communities, populations, organisms
●● Biosphere
Answer: broadest level encompassing planet earth and the atmosphere;
all capable of sustaining living organisms
●● Ecosystem
Answer: a system of living and non-living things in a region. Grasslands,
forests, desserts, tundra, savanna, aquatic regions, rainforests, and coral
reefs including the plants, organisms, soils, and climate conditions
associated are all examples of ecosystems.
●● Communities
