Rio Bio 156 Exam 1 Questions and
Correct Answers
List features that distinguish living organisms from
nonliving matter. Answer: 1. Cellular basis - All living
things consist of one or more cells
2. Requirement for energy and nutrients - Life is
sustained by ongoing inputs of energy and nutrients
3. Homeostasis - Living things sense and respond to
change
4. DNA is hereditary material - Genetic information in
the form of DNA is passed to offspring
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

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
