DNA contains the code for making the protein (or
for sequencing the amino acids). If the DNA
changes, the new coding could be for a different
protein (or sequence of amino acids).
19
Possible answers for part B include
Thorugh, RNA, the DNA code leaves the nucleus and
guides the construction of the protein in the
ribosomes in cytoplasm. OR RNA is used to
pick up amino acids and bring them to where the
protein is being made (that is, the ribosome).
OR RNA makes sure the building blocks of
proteins (that is, amino acids) are put in the
correct order in the protein.

Because of energy loss in transfer, it takes a
lot of energy (food, individual prey) to go from
one level in the food chain to the next. Higher
trophic levels have less energy available than
lower levels do. About 90 percent of the energy
is lost during the transfer from one level to the
next. Only about 10 percent of the energy
available is transferred from one level to the
next.
21
Possible locations include carbon in living
organisms carbon dioxide in air carbon
compounds in remains of living organisms coal
diamond fossil fuels graphite
limestone or carbonates (Note Do not accept
just rock.)
22
Short-period processes or changes
earthquakes volcanic eruptions flash floods
tornadoes hurricanes landslides
avalanches
23
Long-period processes or changes changes in
the oxygen content of the atmosphere plate
tectonics (uplifting and weathering of mountains)
formation of coal deposits formation of
sedimentary rock
NOTE Either short- or long-period processes or
changes (depends on description) delta
formation coastal erosion river changes
course (meandering rivers)

4.5 cm to 5.0 cm OR The nail will be driven
into the wood a distance that is about double
that when it was dropped from 20 cm.
Data for trials 4 and 6 show that when the
distance the weight falls doubles, the distance
the nail is pushed into the wood also doubles.
Trial 2 shows that when a 2-kg mass falls 20 cm,
the nail is pushed into the wood 2.4 cm.
Therefore, when the same 2-kg mass falls 40 cm,
the nail should be pushed into the wood 4.8 cm
(2.4 cm 2).
