|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


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

|\ |\ |\ |\ |\ |\ |\ |\ |\


between them. - CORRECT ANSWERS ✔✔1. Fungi can be single or

|\ |\ |\ |\ |\ |\ |\




3. Animals are multicellular and eat other organisms for
|\ |\ |\ |\ |\ |\ |\ |\ |\


nutrients. |\




4. Protists are the unicellular organisms that have a nucleus but

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.
