IS CORRECT?

2
Answer D is correct, because an individual can't
change his/her own genes in a certain way through
certain activities. Mutations certainly occur
during an organism's lifetime, but they are
completely unpredictable, and very unlikely to
take place in reproductive cells like eggs and
sperm. Answers A, B, and C are all related to the
Lamarckian idea that traits acquired during the
lifetime can be passed to offspring.
3
Answer B is correct because it refers to
competition for water and sunlight. Answer A is
wrong because organisms compete with others like
themselves, not just other species.Answer C says
that plants do not compete, which is inaccurate.
Answer D denies that resources are ever limited.
4
Character A has the best answer. A trait
typically becomes more common if there is some
advantage to organisms that have that trait.
Answer B is irrelevantAnswer C reflects a
common misconception that dominant alleles are
somehow stronger. Answer D is wrong Mutations DO
NOT always have negative effects.  
5
Answer B is the best because Spot has won the
reproduction contest. The organism able to pass
on genes to more offspring than the other guy is
the most "fit" in biological terms. Answers A
and C are misconceptions the biggest, strongest,
and fastest are not always the MOST FIT EX
using energy more efficiently, being able to
withstand extreme conditions, or being better
camouflaged than other members of the population
can make an organism the most fit in an
environment. Answer D mating doesnt always
guarantee surviving offspring most dont make it
6
Character C is correct, because mutations are
always random changes in the DNA sequence.
Characters A and B are wrong because certain
individuals have a better chance of surviving
based on the traits they possess. These are not
random eventsD is wrong because only the
occurrence of mutations is random who you mate
with and who gets eaten are not.
7
Character B is correct since reproduction
typically takes place whether there are enough
resources or not. Obviously, all of the offspring
will not survive if times are tough. Most
organisms have no control over the number of
offspring they produce. 
8
Answer B is most accurate, due to variation in
large populations of insects. The few ants that
may be able to survive the spray will reproduce
to make the next generation. Answer A is wrong
because all populations have natural
variation.Answer C is wrong resistant ants in
next generation come from reproduction of parent
ants that were resistant.
9
Character C is correct. All bacteria do not
acquire resistance, and people do not become
resistant to antibiotics (although the bacteria
inside them can).
10
Correct answer it depends on the environment
There is NO BEST characteristic. Different
characteristics would make an organism the
fittest in different environments! Organisms
within populations typically vary in many
respects. "A" may have a greater chance of
surviving to reproduce than "B" if an herbicide
is used, but not if hungry caterpillars are a
problem. "D" may be a real winner at attracting
more insects, but may require more water than
"C".
11
Character A is correct, although mutation is only
one of two sources of genetic variation - the
other is sexual recombination. Answers B and C
are not accurate because they are really
backwards. Natural selection works on variation
that already exists, and the same is true for
adaptation. Variation allows adaptation to take
place.
12
Character C is correct, and various blood types
are just one example of human variation. Answer A
reflects the common but mistaken idea that
although we look different on the outside, we are
all the same on the inside. Answer B is correct
in that our environment does influence how we end
up, but genes definitely ARE involved.
