7 characteristics shared by living organisms - correct answer ✔✔ 1. cellular organization
2. ordered complexity
,3. sensitivity
4. growth, development, and reproduction
5. energy utilization
6. homeostasis
7. evolutionary adaptation
cellular organization - correct answer ✔✔ all organisms consist of one or more cells. Often to
tiny to see, cells carry out the basic activities of living, each cell is bounded by a membrane that
separates it from its surroundings.
ordered complexity - correct answer ✔✔ all living things are both complex and highly ordered.
Your body is composed of many different kinds of cells, each containing many complex
molecular structures.
sensitivity - correct answer ✔✔ all organisms respond to stimuli. Plant grow toward a source of
light, and the pupils of your eyes dilate when you walk into a dark room
growth, development, and reproduction - correct answer ✔✔ all organisms are capable of
growing and reproducing, and they all possess hereditary molecules that are passed to their
offspring, ensuring that the offspring are of the same species
energy utilization - correct answer ✔✔ all organisms take in energy and use it to perform many
kinds of work. Every muscle in your body is powered with energy you obtain from your diet
homeostasis - correct answer ✔✔ all organisms maintain relatively constant internal conditions
that are different from their environment, your body temperature remains stable despite
changes in outside temperature
, evolutionary adaptation - correct answer ✔✔ all organisms interact with other organisms and
the nonliving environment in ways that influence their survival, and as a consequence,
organisms evolve adaptations to their environments
hierarchical organization of living systems - correct answer ✔✔ atoms, molecules,
macromolecules, organelle, cell, tissue, organs, organ system, organism, population, species,
community, ecosystem, biosphere
atoms - correct answer ✔✔ elements of matter
molecules - correct answer ✔✔ atoms joined together in clusters
organelle - correct answer ✔✔ tiny structures that complex molecules are assembled into
cells - correct answer ✔✔ basic unit of life
tissue - correct answer ✔✔ groups of cells that act as a functional unit
organs - correct answer ✔✔ body structures composed of several different tissues that act as a
structural and functional unit
organ system - correct answer ✔✔ consists of sensory organs
population - correct answer ✔✔ a group of organisms of the same species living in the same
place
species - correct answer ✔✔ members similar in appearance and able to interbreed
