Rio Salado College Rio Bio 156 Exam 1 || Top Grade Assured.
List features that distinguish living organisms from nonliving matter. correct answers 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. correct answers Atoms → cells → tissues
→ organs → organ systems → organism → population → community → ecosystem → the
biosphere
List the three domains of life and distinguish between each domain. correct answers 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. correct answers 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 correct
answers observation
hypothesis
experimental
, conclusion
Describe the concept "an organism is more than the sum of its parts." correct answers 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. correct answers
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. correct answers
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. correct answers 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? correct answers a hypothesis can
be proven that is false
Define the term control group and explain the value of a control group in an experiment. correct
answers 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
