Rio Bio 156 Exam 1 QUESTIONS WITH
|\ |\ |\ |\ |\ |\ |\
ANSWERS
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
|\ |\ |\ |\ |\ |\ |\ |\ |\
Define the term theory and explain the point in which a
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
hypothesis becomes a theory. - CORRECT ANSWERS ✔✔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.
