BIOLOGY 111 EXAM 1 (CH.1-4) QUESTIONS &
ANSWERS
Properties of living things - Answer -Order, DNA, Reproduction, Growth &
Development, Energy Processing, Regulation/Homeostasis, Evolutionary Adaptation
Central Themes in Biology - Answer -Emergent, Living things are organized,
Organisms interact with their environments, Life Requires energy transfer and
transformation, Structure correlates with function
The Cell - Answer -Basic Unit of Life, Smallest unit that inhibits all properties of life,
What molecule has genes and is considered the molecule of inheritance in all living
things? - Answer -DNA
Life is regulated by... - Answer -Feedback mechanisms
Importance of feedback mechanism - Answer -For increasing or decreasing the output
of a particular molecule
Evolution - Answer -Change of traits of a population over time
Taxonomy - Answer -The classification and naming of living things
Biology - Answer -Study of living things
Why is evolution a central theme in biology? - Answer -It explains diversity and unity of
life
What is the Linnaen classification of organisms? - Answer -Hierarchical system where
levels of classification are subsets of others
List of Linnaen groups from most general to most specific (Did King Philip Come Over
For Good Soup) - Answer -Domain, Kingdom, Phylum, Class, Order, Family, Genus,
Species
Domains of living organisms - Answer -Bacteria, Archaea, Eukarya
Kingdoms in domain eukarya - Answer -Plants, Animals, Fungi, Protists
Who was the scientists who published "The Origin of Species" that explained evolution
by natural selection? - Answer -Charles Darwin
, Steps of Natural Selection - Answer -1. Population shows phenotypic variation
2. Variations are reliably heritable
3. Competition between variants for limited resources
4. Those with certain traits will survive/reproduce rather than those who struggled to
survive
5. Outcome: Population will show increase of individuals with traits that were able to
survive better
Adaptation - Answer -Trait used to survive and reproduce in given environment
Why is natural selection considered a "mechanism" of evolution? - Answer -It works as
a process
Inductive Logic - Answer -Goes from particular instances to a general premise;
Conclusions are no usually certain
Deductive Logic - Answer -Goes from a general premise to particular instances
Scientific Method - Answer -1. Observe
2. Make a hypothesis
3. Make a prediction on what will happen if hypothesis is proved
4. Conduct experiment
5. Analyze your data
Independent Variable - Answer -The factor of interest
Dependent Variables - Answer -The outcome/response
Control Group - Answer -Receives all conditions except the factor of interest
Comparative Groups - Answer -Comparing levels of independent variable
What is the difference between a hypothesis and a theory? - Answer -A hypothesis is a
tentative explanation for an observable phenomenon, a theory is a set of ideas that
explain things broadly and is supported by lots of evidence
what are the roles of comparative and control groups in an experiment? - Answer -
Comparative compares the results from two or more versions of the independent
variable. Control groups is used to determine if the independent variable is the cause of
the results.
Matter - Answer -Takes up space and has mass
What are the three states of matter? - Answer -Solids, liquids, gases
Element - Answer -Substances that can't be broken down by chemical reactions
