Apple farmers are currently having a very difficult time with pesticide-resistant insects. In reaction,researchers are developing newer and stronger chemicals to help control the bugs. Why are the apple farmers seeing these new, stronger bug?
a) The bugs were not native to the area and thus cannot be killed by normal chemicals.
b) Changes in the weather have led to stronger insects that can survive these harsh changes.
c) The strongest bugs were able to survive pesticides, reproduce and create more resistant pests.
d) The apple trees are producing too many apples, which is allowing the insects to reproduce rapidly.

Suppose that pollution caused snow in the arctic to quickly turn black, which happens sometimes in today’s urban areas. To adapt to this change over time, the arctic fox’s fur would
a) darken in the summer.
b) darken in the winter.
c) lighten in the summer.
d) lighten in the winter.

During the late carboniferous, Indiana was close to the equator and had many swamps and wetlands. Plant material accumulated in these areas of Indiana and eventually became the source of Indiana’s abundant
a) coal deposits.
b) granite outcrops.
c) limestone deposits.
d) layers of sandstone.

The tundra and taiga have unique characteristics which help distinguish them from each other. Which of these physical factors led to the differences found in these biomes?
a) The tundra is colder and receives less rainfall than the taiga.
b) The tundra is colder and receives more rainfall than the taiga.
c) The tundra is warmer and receives less rainfall than the taiga.
d) The tundra is warmer and receives more rainfall than the taiga.

Virginia was a sea during Cretaceous time. The sea level receded making a plateau. Under these conditions, we would expect to find more fossils of ____________ life forms in this location.
a) marine
b) primitive
c) single-celled
d) terrestrial

Some giraffes have long necks and some have shorter necks. The ones with longer necks can reach food sources like tall trees as well as eat grasses on the ground. How will this difference MOST LIKELY help the giraffe population?
a) Their number will remain unchanged.
b) Over time, more will have longer necks.
c) Giraffes will move from place to place for food.
d) There will be great differences among the giraffe population.

What adaptation would you expect to see in moles (which live underground)?
a) Moles have developed special claws used for clutching their young.
b) Moles have developed markings that help them identify one another.
c) Moles have developed a special pouch to keep newborn mole babies in.
d) Moles have developed a membrane that can keep dirt out of their eyes.

The early ancestors of the horse were adapted to life in tropical forests. Gradually the forests disappeared and were replaced with open grasslands. Because of the gradual change in habitat, modern horses
a) have five toes that allow them to walk well on soft ground.
b) are herbivores instead of carnivores like their early ancestors.
c) are taller with long legs and are capable of great speed to escape predators.
d) have gradually grown larger, but show no major changes from the early ancestors.

The tundra is cold year-round. it has short cool summers and long, severe winters. Which adaptations would you expect to see in plants growing in the tundra?
a) leaves with hair help shade the plant, reducing water loss.
b) small and grow in clumps for protection from the wind and cold
c) deep roots to help capture nutrients from deep below the surface
d) tall plants with broad, thin, waxy leaves leaves so water easily runs off

Green algae is ancestors of land plants. The classification division separating algae from the kingdom Plantae began with fossil evidence. To be successful land plants require certain modifications. This early Devonian land had vascular tissue and
a) chlorophyll.
b) roots.
c) seed pods.
d) spores.

The LaBrea tar pits in California contain grazing animals and grasses, sagebrush and trees. Fossils found in the La Brea tar pits indicate a California climate that was
a) similar to today's climate.
b) similar to the present-day tundra.
c) desert-like, much drier and hotter than today.
d) milder than today's climate, with high precipitation.

The discovery of the fossils of prehistoric whales that lived millions of years ago in Mississippi indicate that
a) the whales were once land-dwelling mammals.
b) the whales lived in an inland sea, which dried up.
c) the Gulf of Mexico once covered what is now the State of Mississippi.
d) the whales were hunted by the native American tribes that lived along the river.

Which of these would best describe what Darwin saw as the MAJOR difference(s) between these finches?
a) They all ate different food
b) They all lived in different areas
c) Both where they lived and what they ate were different
d) Only their beak size was different and they lived together and ate the same food.

Stingrays, catfish, and scorpion fish all have an adaptation that helps protect them against predators. This adaptation is
a) venom.
b) mimicry.
c) camouflage.
d) electric organs.

The study guide image shows four different finches Charles Darwin found while on the Galapagos Islands. Which of these would be most adapted to eating nuts and seeds?
a) Geopiza fortis
b) Geopiza parvula
c) Certhidea olivacea
d) Geospiza magnirostris

Some nonpoisonous snakes, like the king snake look a lot like a poisonous variety. In this case, the king snake looks like the deadly coral snake. The king snake is not attacked by predators and survives. This adaptation is called
a) camouflage.
b) evolution.
c) mimicry.
d) variation.

Two major divisions of land animals moved ashore, first the arthropods and then the tetrapod vertebrates. What fossil evidence BEST supports the classification of animals into these two basic branches, still recognized today?
a) fossilized amniotic eggs
b) impressions of scales versus fur
c) evidence of exoskeletons and endoskeletons
d) fossilized bones with and without air cavities

a) mass clonings
b) microevolutions
c) mass extinctions
d) mass revolutions

20,000 years ago, two populations of the black-tailed rats became separated from each other by the formation of a large canyon, thus preventing their interbreeding. The condition described is

b) Thorns are an example of a mutation that arises in the genetic code of plants.
c) Thorns help plants to conserve resources like water and soil nutrients that may be used by other organisms.
