Principles of Biology 101 UPDATED
ACTUAL Exam Questions and CORRECT
Answers
Charcteristics of living organisms: - CORRECT ANSWER - 1. organized into units,
2. acquire materials and energy from; they need a source of nutrients from outside themselves,.
3. reproduce, - they produce offspring that resemble themselves.
4. respond to stimuli,
5. Homeostasis- stay just about the same despite the external environment
6. grow and develop,
7. have to capacity to adapt to their environment,
Homeostasis: - CORRECT ANSWER - Maintenance of normal internal conditions in a
cell or an organism by means of self-regulating mechanisms
Classifications of organisms: - CORRECT ANSWER - -Systematics
-Domains
-Kingdoms
Systematics: - CORRECT ANSWER - the discipline of identifying and classifying
organisms according to specific Criteria. Each organism is placed into a Domain, Kingdom,
Phylum, Class, Order, Family, Genus, and finally Species
Domains: - CORRECT ANSWER - Archea-
Bacteria-
Eukarya-
Kingdoms: - CORRECT ANSWER - Protists
,Fungi
Plants
Animals
Classifications from most inclusive to least inclusive: - CORRECT ANSWER - Domain,
Kingdom,
Phylum,
Class,
Order,
Family,
Genus,
Species,
Levels of biological organization: - CORRECT ANSWER - ATOM (smallest unit of an
element composed of electrons, protons, and neutrons) -->
MOLECULES (Union of tw or more atoms of the same or different elements) -->
CELLS(The structural and functional unit of all living things) -->
TISSUES (a group of cells within a common structure and function) -->
ORGANS (Composed of tissues functioning together for a specific task) -->
ORGAN SYSTEMS (Composed of severla organs working together) -->
ORGANISMS (an individual; complex individuals contain organ systems) -->
POPULATIONS (Organisms of the same species in a particular area) -->
COMMUNITIES (Interacting populations in a particular area) -->
ECOSYSTEM (a community plus physical environment) -->
BIOSPHERE (regions of the Earth's crust, waters, and atmosphere inhabited by living things
Ecosystems: - CORRECT ANSWER - In an ecosystems populations interact with one
another and their physical environment
, Taxonomy: - CORRECT ANSWER - branch of biology concerned with identifying,
describing, and naming organisms.
organization of biosphere: - CORRECT ANSWER - -population
-community (group of populations)
-ecosystems (community + abiotic environment)
-biosphere
biodiversity: - CORRECT ANSWER - how diverse an ecosystem is
Biology: - CORRECT ANSWER - the scientific study of life
The process of science: - CORRECT ANSWER - Observation -->
Hypothesis -->
Experiment/observations-->
Conclusion (analyze data to support or reject hypothesis) -->
Scientific Theory
Technology is... - CORRECT ANSWER - is the application of knowledge for a practical
purpose.
Technology has both benefits and drawbacks
Ethical and moral issues surrounding the use of technology must be decided by everyone.
Responsibility for how to use scientific technology must reside with people from all walks of
life, not with scientists alone.
DQ; Are crystals alive? - CORRECT ANSWER - no, they are not alive. They do not grow,
they accumulate
