The hereditary material in corn plants can be altered by scientists so the plants produce more corn. Which term identifies this process?

When the environment changes more quickly than a species can adapt, the species may become:
A-extinct
B-dominant
C-Diverse
D-Overpopulated

Which process involves choosing certain organisms to reproduce with another in order to pass on specific, desirable traits to their offspring.

The drawings below represent three different birds. The beak shape makes it easy for each bird to obtain food in a different way. The differences in beak shape are examples of:
1-camouflage
2-dynamic equilibrium
3-competition
4-biological adaptation

The fur of the snowshoe rabbit changes to a lighter color in the winter. This allows the rabbit to blend in with its surroundings. This change is an example of:
1-extinction
2-competition
3-biological adaptation
4-ecological succession

A farmer develops seeds that are resistant to a fungal disease by crossing two disease resistant plants.

Any variation that can help an organism survive it in its environment is called:
A-adaptation
B-characteristic
C-competition
D- vestigal structure

A farmer found that if the temperature of the barn was kept 5 degrees warmer, the cows in the barn produced more milk.

What factor might contribute to the extinction of this species of woodpecker?
A- a new source of food
B-an overabundance of trees
C-the use of pesticides in the forest
D-an increase in the population of insects

The diagram below shows a population of adult giraffes over time. Letters A, B, C represent three time periods. Which process does this diagram represent?
1-ecological succession
2-genetic engineering
3- natural selection
4-asexual reproduction

The transfer of a section of DNA from one organism into the DNA of another organism by scientists is called:

Which of the following describes camouflage:
A-A viceroy butterfly looks like a monarch, so blue jays are less likely to eat them.
B- A Snowshoe Hare changes its fur color from brown to white to blend in with the snow during the winter.
C-Blue footed bird do a dance to attract mates
D- A spotted salamander has bright yellow spots to warn predators that it is toxic

A new variety of a tomato is better tasting and can be stored longer than the other tomato varieties. This new tomato is produced by placing additional gene segments into the cells of the tomato plant. This process is known as:

The effects of natural selection are generally seen most quickly in which organisms.
A-bacteria
B-humans
C-Corn Plants
D-Cats

The photograph below shows a cactus plant. Which feature helps a cactus plant prevent water loss in a hot, dry, desert environment?
1-green color
2-flowers
3-waxy surface
4-branches

A farmer mated his cattle with larger cattle. The offspring weighed more and provided more meat.

What is the definition of species:
A-a trait that helps an organism survive and reproduce.
B-a group of similar organisms that can mate and produce fertile offspring.
C-a well tested concept that explains a wide range of observations
D- a group of animals with similar appearance

A farmer planted corn seeds in the field two weeks earlier than usual. The earlier start yielded (made) more corn.

The diagram below shows the head structure of four different birds: Falcon, Sparrow, Hummingbird, Mallard. The birds beaks show how the birds:
A-compete for the same food in their community
B-require different amount of food for survival
C-Store food for the winter months.
D-are adapted to get food from different sources.

Feathers, wings, and the hollow bones of birds are examples of:
1-adaptations for flight
2-responses to stimuli
3- unnecessary body parts
4- reproductive structures

A Puggle is a type of dog first produced by mating two other types of dogs, a pug and a beagle. This process is an example of:

Read the following statement (#24): As used in this passage: what word does the word "specialized" mean?
A-well trained and obedient
B- drastically mutated to become more powerful
C-well-suited for a particular environment
D-very talented.

The illustration below traces the development of the corgi dog over several generations as a result of human activity. This is an example of human activity is called:

The finches on the Galapagos Island were similar in form except for variations of their beaks. Darwin observed that these variations were useful for:
1-attracting a mate
2-defending territory
3- building nests
4-gathering food

What is regarded ( known as) the the "father of evolution?"
1-Lamarck
2-Einstein
3-Wegener
4- Darwin
