Transcript Warm up # 21

Warm up # 28
( Unit 2 Article Due Tomorrow)
1) What do you know about the following
terms:
a) Evolution
b) Community
c) Extinction
d) Genes
2) Describe what you see in video on “Maple
Copters”
Things in nature look the way they do for a
reason. Organisms that have an
advantage will survive. Other organisms
will go extinct.
In nature there are 2 keys to survival:
gaining energy and reproducing.
Warm Up # 22
1) What makes you unique?
2) What does the word “evolution” mean?
3) Why do you think species would change over
time?
Warm Up 29
1) You and a friend are chased by a grizzly bear. List some
possible ways you can survive. (not harming the bear)
2) A school of fish are chased by a shark, which fish gets
eaten?
3) Which of the fish are most likely to reach
adulthood and reproduce?
4) What does the word “evolution” mean?
Things in nature look the way they do for a
reason. Organisms that have an
advantage will survive. Other organisms
will go extinct.
In nature there are 2 keys to survival:
gaining energy and reproducing.
Warm Up 30 (5 questions)
1) Explain how this diagram illustrates
evolution?
2) A reintroduced population of wolves in a
national park is 90% grey and 10% black,
consistent with the wolf population in other
regions. After several generations in
isolation, the national park’s wolf population
is 60% grey and 40% black. The wolf
population has likely experienced
A. natural selection.
B. genetic drift.
C. mutations.
D. migration.
3) How is the fish on the bottom an
example of evolution by mutation?
4) Explain resistance.

Need to fit your habitat!
5) Explain how/why a desert fox might look
different than one in Audubon.
Warm Up 31: Matching…8 questions
1) Humans breed dogs
2) Genetic characteristics of
population change
3) Bacteria are not killed by
hand sanitizer
4) Camouflage of insect keeps
it safe
5) More camouflage insects
survive and reproduce
a) natural selection
b) evolution
c) artificial selection
d) adaptation
e) resistance
6) What is co-evolution?
7) Describe how an organism
must FIT its environment.
8) One of the conditions for natural selection is
“Individuals vary in fitness, or reproductive
success” Explain what that means.
Warm Up 32
1) Explain what an adaptation is and how
“NATURE SELECTS?”
2) One of the conditions for natural selection is
“Individuals vary in fitness, or reproductive
success” Explain what that means.
3) Explain what resistance is, and why it is a
problem?

fittest (natural selection)?
3) What happens to a species if it is unable to adapt
to changes in its environment?
What do you know about the following terms:
a) Predator
b) Prey
c) Parasite
d) Herbivore
e) Mutualism

either positive (+), negative (-) interaction, or no
impact (o).

eating the grass how many unit of energy would
the mouse have?
4) In an ecosystem why are there so few owls
compared to grass?

latitude decreases (closer to equator)?
Yesterday You Learned…
1) There is a huge diversity of life on Earth that
is critical to all species.
2) We call that variety of life BIODIVERSITY.
3) There are 3 types: ecosystem, genetic and
species diversity.
4) Biodiversity is important for: food webs to
function, medical reasons, ethical reasons
and more
