which of the following is NOT a characteristics of a stable, non-evolving population?

there is no migration in or out of the population

there is no natural selection in the population

Which of the following best describes an adaptation?

trait that allows an organism to be better suit for survival

A tight bundle of genetic material in the nucleus of cells

A segment of DNA that codes for a trait

A harmful trait that hurts an organism's chance of survival

Which of the following is true about extinction?

Most species that have lived on Earth are now extinct

No animals currently living on Earth will become extinct

fossil record doesnt give clues which lifeforms are extinct

Little is known about all extinct organisms.

Which of the following is most closely linked to Charles Darwin's concept of natural selection?

Predator-prey relationships influence change among organisms

Competition strongly influences change among organisms

Reasons for preserving biodiversity include all of the following EXCEPT

preventing natural evolution or for poaching

isolating unique genetic material so it can be incorporated into existing crops.

increasing the chances of discovering organisms with medicinal value.

finding new plants that can supplement the world’s food supply

Where are many critical Biodiversity Hotspots located?

islands, tropical rain forests, and coastal areas

cities and developed areas of the world

Hunting wolves in Yellowstone National Park resulted in -

complete influx of different organisms

beneficial changes in the geography in the land.

Preserving entire ecosystems rather than individual species is a good conservation strategy because

more than one species can be saved.

only endangered species will be saved.

developers will have greater access to land.

it will not be necessary for environmentalists to study the ecosystem.

How can zoos, botanic gardens, and wildlife parks help save species?

by preserving threatened species from destruction.

by participating in captive breeding programs

by collecting species from remote wilderness areas.

What does biodiversity mean?

The different amount of species in an area

A drought has hit this grassland biome. How will this effect the rabbit population?

The rabbit population will decrease.

The rabbits will increase in number.

The rabbit population will stay the same.

The rabbit population will become extinct immediately.

Why are advantageous traits more likely to be passed onto offspring?

Because they are more likely to survive and reproduce.

Because they come from dominant alleles.

Because they come from recessive alleles.

Because the trait is an acquired phenotype.

If the environment suddenly changed, how could a species go extinct?

There aren't enough members of the species with a trait necessary to survive in the new environment

The environmental change means fewer predators are around

There are more homes available in the newly changed environment

New resources are available with less competition

Penguins are powerful swimmers. Scientists have concluded that penguins evolved adaptations for powerful swimming early in their evolutionary history. Which of the following pieces of evidence did scientists most likely use to make this conclusion?

fossils showing the shape of ancient penguins’ wings and feathers

DNA sequences of different penguin species

maps of the global distribution of penguin species

x-rays of the bone structure in modern penguins’ wings

The term biodiversity refers to

the variety of species on Earth

the extinction of the dinosaurs

habitat destruction, invasive exotic species & poaching

the fact that 10% of prescription drugs come from living things

Most of the living species known to science

live in the richer countries of the world

Emphasizing the preservation of entire ecosystems will

save many unknown species from extinction

cause the economic needs of farmers to suffer in order to save a single species

decrease biodiversity, especially in tropical rain forests, coral reefs and islands

throw the food webs of many ecosystems out of balance

What human activities have influenced recent extinction events?

introducing exotic (alien) species

What is Ecological Succession?

The change an ecosystem experiences over time

Competition between plants in a society

A natural disaster such as a flood or fire

A scientist observes two butterflies with similar wing patterns. Which of the following observations would best show that the two butterflies belong to the same species?

The butterflies mate with each other and produce fertile offspring.

The butterflies share a habitat.

The butterflies pollinate the same flowers.

The butterflies make a chrysalis and not a cocoon for metamorphosis.

Which of the following observations best supports the conclusion that dolphins and sharks do not have a recent common ancestor?

The jawbone structure in dolphins is very different from the jawbone structure in sharks.

Dolphins form social groups, but sharks are solitary.

Dolphins hunt during the day, but sharks are nocturnal.

The number of dolphin species is far less than the number of shark species.

Fossils typically provide evidence for evolution because

they show patterns of biological change.

they are millions of years old.

they exist in all types of rocks.

they supply good samples of RNA.

Which of the following relationships is the best example of mutualism?

a bee eating nectar and pollinating flowers

a coyote killing and eating a rabbit

a parent tree blocking sunlight from reaching a seedling tree

Which of the following statements describes a role of plants in the water cycle?

Plants release water vapor into the atmosphere during transpiration.

Plants release water from their roots into the soil.

Plants transfer water to bacteria during nitrogen fixation.

Plants convert water vapor into carbon dioxide during photosynthesis.
