Biol 1406 - DCCCD Exam 1 questions
n answers graded A+
Define "Biology" - correct answer ✔✔ Biology is the scientific study of life
Distinguish between living and non-living things - correct answer ✔✔ Living things are
characterized by eight characteristics of life, while non-living things do not exhibit the same
characteristics. Living things represent a highly coordinated set of chemical and physical
processes that are manifested as the phenomenon we call life.
What are the eight characteristics of life? - correct answer ✔✔ Specific Organization,
Metabolism, Hemostasis, Growth, Movement, Responsiveness, Reproduction, and Adaptation
Specific Organization - correct answer ✔✔ Refers to cellular organization and to the
commonality of organization shared between all living things.
Metabolism - correct answer ✔✔ The total or sum of all chemical activity in a living thing
Homeostasis - correct answer ✔✔ The maintenance of a constant internal environment
Growth - correct answer ✔✔ An increase in size by the addition of new living tissue; the
formation of new cytoplasm and cell parts.
Movement - correct answer ✔✔ Movement that results from the efforts and expenditure of
energy by the organism
, Responsiveness - correct answer ✔✔ The ability to sense and respond to stimuli from the
environment and from within
Adaptation - correct answer ✔✔ The ability of a population or species to adjust to the
environment over time through genetic change. Individuals do not adapt; they acclimate as they
adjust to the environment within their individual range of genetic tolerance.
energy utilization - correct answer ✔✔ Biological and ecological organization ranges from atoms
or atomic particles to the biosphere which is all life on Earth and its physical environment.
List and Describe the levels of biological organization: Atom - correct answer ✔✔ Smallest or
simplest particles of an individual element that exhibits its chemical and physical characteristics,
i.e. hydrogen, oxygen, carbon.
List and Describe the levels of biological organization: Molecules - correct answer ✔✔ Any two
or more atoms bonded together
List and Describe the levels of biological organization: Organelles - correct answer ✔✔ Cell parts
such as mitochondria, chloroplast, nucleus, etc.
List and Describe the levels of biological organization: Cells - correct answer ✔✔ The basic unit
of life. All living things are composed of cells and/or cell products.
List and Describe the levels of biological organization: Tissues - correct answer ✔✔ Groups of
similar cells that are specialized for one, sometimes two specific functions, i.e. muscle, nerve.
List and Describe the levels of biological organization: Organs - correct answer ✔✔ Structures
composed of two or more tissues dedicated to one to a few function, i.e. stomach, heart, liver.
