Rio Bio 156 Exam Questions with 100% Correct Answers Latest
Graded A+
Question:
List features that distinguish living organisms from nonliving matter.
Answer:
1. Cellular basis - All living things consist of one or more cells
Question:
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
Question:
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
Question:
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.
Question:
,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
Question:
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.
Question:
By definition, distinguish between a population, a community, and an ecosystem.
Answer:
1. Population: multiple organisms in a single spot
Question:
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.
Question:
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.
Question:
What is meant by the phrase potentially falsifiable hypothesis?
Answer:
a hypothesis can be proven that is false
Question:
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
Question:
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.
Question:
Explain how electron configuration influences the chemical properties of an atom.
Answer:
Each cloud can hold a determinant number of electrons. When the electron number changes, ions
are formed. The number of electrons influences the bonding between atoms.
Question:
hydrogen bond
