Question 5 – 3 points
 Why would the roots of desert plants most
likely be deeper than the roots of most plants
found in the tropical rain forest?
Question 5 – 3 points
 Why would the roots of desert plants most
likely be deeper than the roots of most plants
found in the tropical rain forest?
- In a rain forest, there is plenty of water available,
roots don’t need to grow very deep.
OR
- In a desert, there is less available water, so roots
grow deeper to collect the available water.
Question 6 – 2 points
 On many desert plants, modified leaves
called needles grow. This conserves energy
and reduces transpiration. Where then does
photosynthesis occur?

Question 11 – 4 points
 What is the basic difference between natural
selection and selective breeding?
Question 11 – 4 points
 What is the basic difference between natural
selection and selective breeding?
 Natural selection is a process that occurs in the
wild. Changes occur because of environmental
influences.
 Selective breeding is an artificial, man-made
process where humans select the traits that are
most desired for our purposes.
Question 12 – 3 points
 Which of the following is the best example of
natural selection?
A. a great dane winning a dog show
B. a female peacock picking the most colorful
male to reproduce with
C. picking out really fluffy gray kittens at the pet
store
D.growing really big apples
Question 12 – 3 points

natural selection?
A.
B. a female peacock picking the most colorful
male to reproduce with
C.
D.
Question 13 – 4 points
 Explain why the many species of Galapagos
Islands finches have so many different types
of beaks.
Question 13 – 4 points
 Explain why the many species of Galapagos
Islands finches have so many different types
of beaks.
 Each of the finches have specialized in consuming
different available food, requiring different beaks
that had to change slowly over many generations.
Question 14 – 3 points
 What is the process that occurs when species
that are most suited to their environment
survive and get to pass on their successful
traits to their offspring?
Question 14 – 3 points
 What is the process that occurs when species
that are most suited to their environment
survive and get to pass on their successful
traits to their offspring?
 Natural Selection
Question 15 – 3 points
 Xylem is an adaptation that allows water to
travel against gravity up to the top of plants
from their roots. What does this adaptation
allow plants to do? (Hint: Plants compete for
sunlight)
Question 15 – 3 points
 Xylem is an adaptation that allows water to
travel against gravity up to the top of plants
from their roots. What does this adaptation
allow plants to do? (Hint: Plants compete for
sunlight)
 Xylem allows plants to grow taller, thus possibly
reaching more light than their competition.
Question 16 – 3 points
 There are behavioral traits that are also
important adaptations that help a species
survive. If a specie lives in an area that faces
increasingly colder weather every year, what
would a likely behavioral adaption be?
Question 16 – 3 points
 There are behavioral traits that are also
important adaptations that help a species
survive. If a specie lives in an area that faces
increasingly colder weather every year, what
would a likely behavioral adaption be?
 migration
 hibernation
Question 17 – 3 points

at the grocery store gotten so big?
Question 17 – 3 points
 Why have many of the fruits and vegetables
at the grocery store gotten so big?
 Selective Breeding
Question 18 – 4 points
 Identify something in an animal’s
environment that could require an
adaptation.
Question 18 – 4 points
 Identify something in an animal’s
environment that could require an
adaptation.
 available food
 available water
 lack of shelter
 lack of mates
Question 19 – 3 points
 Why would some bats have developed the
ability to navigate through the air based on
hearing their own clicking sounds bounce off
of their surroundings? (echolocation)
Question 19 – 3 points
 Why would some bats have developed the
ability to navigate through the air based on
hearing their own clicking sounds bounce off
of their surroundings? (echolocation)
 The bats that survived were those that were able to
hunt at night, in the dark. Ancestors with those traits
survived and that ability slowly got better and better of
many generations.
