1. List features that distinguish living organisms from nonliving matter.: 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
2. Describe the levels of organization in the living world.: Atoms ’ cells ’ tissues
organs ’ organ systems ’ organism ’ population ’ community ’ ecosystem ’ the biosph
3. List the three domains of life and distinguish between each domain.: -
Prokaryotes are bacteria and archaea.
Domain Bacteria: unicellular no nucleus
Domain Archaea: unicellular no nucleus but closer to eukarya
Domain Eukarya: have nucleus
4. List four kingdoms within the domain Eukarya and distinguish between
them.: 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.
5. List and describe the steps involved in solving a problem using hypothe-
sis-based science: observation
hypothesis
experimental
conclusion
6. Describe the concept "an organism is more than the sum of its parts.": -
organism is part of a more complex organization. These emergent properties go
beyond itself.
7. By definition, distinguish between a population, a community, and an
ecosystem.: 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 environ-
ment that surrounds it
8. Distinguish between a producer, a consumer and a decomposer.: produc-
er:photosynthetic organisms that trap light and convert that light energy into chem-
ical 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 biosh-
pere.

9. Distinguish between a hypothesis and a prediction.: hypothesis: testable
explanation of a natural phenomenon.
prediction: statement based on hypothesis about a condition that should exit if the
hypothesis is correct.
10. What is meant by the phrase potentially falsifiable hypothesis?: a hypoth-
esis can be proven that is false
11. Define the term control group and explain the value of a control group in
an experiment.: 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
12. Define the term theory and explain the point in which a hypothesis be-
comes a theory.: 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.
13. Explain how electron configuration influences the chemical properties
of an atom.: 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.
14. hydrogen bond: The electron from the hydrogen spends most of its time around
the oxygen atom creating a partial positive charge on each hydrogen. The presence
of additional electrons makes the oxygen partially negative.
15. covalent bond: two atoms share a pair of electrons, so that each atom's vacan-
cy
becomes partially filled
16. ionic bond: Type of chemical bond in which a strong mutual attraction links ions
of opposite charge.
17. Describe how water contributes to the fitness of the environment that
supports all life.: 1. an excellent solvent
2. has cohesion (insect on water, water roots)
3. stabilize temperature (cool surface)
18. Explain the basis for the pH scale.: The basis for the pH scale is the amount
of H+ and OH- ions in a solution. More H+ ions means a solution is more acidic,
while more OH- ions means the solution is more basic.
19. List and describe the four major classes of organic compounds.: carbohy-
drate
lipid
protein
nucleic acids
