BIO 156 ACTUAL TEST BANK UPDATED
QUESTIONS AND VERIFIED RESPONSES
●● Describe the levels of organization in the living world.
Answer: Atoms → cells → tissues → organs → organ systems →
organism → population → community → ecosystem → the biosphere
●● List the three domains of life and distinguish between each domain.
Answer: Prokaryotes are bacteria and archaea.
Domain Bacteria: unicellular no nucleus
Domain Archaea: unicellular no nucleus but closer to eukarya
Domain Eukarya: have nucleus
●● List four kingdoms within the domain Eukarya and distinguish
between them.
Answer: 1. Fungi can be single or multicellular but digest food outside
their body.
2. Plants are multicellular and are photosynthetic.
3. Animals are multicellular and eat other organisms for nutrients.
4. Protists are the unicellular organisms that have a nucleus but do not fit
any other category.
,●● List and describe the steps involved in solving a problem using
hypothesis-based science
Answer: observation
hypothesis
experimental
conclusion
●● Describe the concept "an organism is more than the sum of its parts."
Answer: organism is part of a more complex organization. These
emergent properties go beyond itself.
●● By definition, distinguish between a population, a community, and
an ecosystem.
Answer: 1. Population: multiple organisms in a single spot
2. community: is made up of populations of different organisms
3. ecosystem: is the interactions between the community and the non-
living environment that surrounds it
●● Distinguish between a producer, a consumer and a decomposer.
Answer: producer:photosynthetic organisms that trap light and convert
that light energy into chemical bond energy. such as some bacteria,
protists, and all plants
consumer: organisms that feed on already-stored food
, decomposer: bacteria and fungi recycle the dead molecules throughout
the bioshpere.
●● Distinguish between a hypothesis and a prediction.
Answer: hypothesis: testable explanation of a natural phenomenon.
prediction: statement based on hypothesis about a condition that should
exit if the hypothesis is correct.
●● What is meant by the phrase potentially falsifiable hypothesis?
Answer: a hypothesis can be proven that is false
●● Define the term control group and explain the value of a control
group in an experiment.
Answer: Group of individuals identical to an experimental group except
for the independent variable under investigation
To provide a basis of comparison to the experimental group
●● Define the term theory and explain the point in which a hypothesis
becomes a theory.
Answer: Suppose a hypothesis stands even after years of tests.
It is consistent with all data ever gathered, and it has helped us make
successful predictions about other phenomena.
