Which of the following is an example of artificial selection?

A farmer only plants seeds from the largest plants in his crop.

biodiversity

Abiotic

common descent

All things come from a single ancestor

Natural selection is the only nonrandom cause of evolution. T/F

True

ecosystem

all the organisms living together in a particular place along with their non-living environments.

botic factors

the parts of an ecosystem that are living or that results from the activities of living things.

When humans play a role in the traits a population of animals have this is called

Artificial selection

descent with modification

Artificial selection

Why are some organisms less generically diverse

Isolation, low population

An organism many other organisims depend on is

Keystone organism

Agro-chemical companies created Golden Rice, a genetically modified food species of rice, to help fight "Blank" in developming countries"

Malnutrition

Natural Selection

Nature decides which traits to keep amd which traits to get rid off

What is least likely to be an example of a variation whitin a species?

Number of limbs

Individual

One single organism

Suppose a new animal is introduced into this desert ecosystem. The new animal has no natural predators. It eats the same plants the wild burros (the horse looking animal) do. Which parts of the ecosystem might be (directly or indirectly) affected by this change? Other animals, plants, flow of energy, cycling matter

Other animals, plants, flow of energy, cycling matter

Which of the following items can be found in an ecosystem? Plants, Animals, Water, Rocks

Plants, animals, water, rocks

Which of the following does NOT provide evidence of natural selection to explain the high percentage of elephants with tusks in the Gorongosa National Park before the Mozambique civil war?

Soldiers purposely bred elephants to have tusks so they could be sold to raise money for weapons.

Biodiversity is made of

Species diversity, ecosystm diversity, genetic diversity

Mongolian gerbils are prey for hawks. If a wildfire blackens the landscape how will the frequency of the a allele for black fur color change compared to the A allele for brown fur color?

The a allele for black fur color will increase compared to the A allele for brown fur color.

In order for natural selection to occur, certain conditions must be present in a population. Which of the following is NOT one of the necessary conditions for natural selection to occur?

The ability for an organism to adapt

The beaks of finches found on various Galapagos Islands varied based on

The available food supply

In the phrase "survival of the fittest", the term "Fittest" refers to:

The best adapted organism

Evolution

The change in inherited traits of a population over many generations

trait distribution

The range of characteristic differences in a population

Why would you put the gene of a fish in a tomatoe?

To keep the tomatoe from freezing?

A change to any part of an ecosystem may disrupt the flow of energy and matter T/F

True

Can you take a gene from a fish and put it into a tomato?

True

Each level of organization (organisms, population, community) gets more complex as more of the environment is considered T/F

True

How quickly an ecosystem can recover depends on the type and serverity of the disturbance.

True

Is natural selection a observable fact T/F

True

The higher percentage of tuskless elephants after the Mozambique civil war is best explained by natural selection T/F

True

The living pares of an ecosystem interact with each other and with nonliving parts. Because of these interactions, ecosystems are dynamic- meanng they are always changing. T/F

True

The playground in the back of the school should be considered an ecosystem T/F

True

Species

organisms of the same king and can successfully reproduce, resulting in fertile offspring.

species diversity

refers to the number of species that are in a given area as well as the number of individuals of each species in a given area.

Ecosystem diversity

refers to the variety of ecosystems in a given area.

Generic Diversity

refers to the variety of genes within a species or population in a given area.

Which of the following is an example of an environmental pressure?

A lake that's gradually running out of water

Monkey flowers are found in a variety of colors ranging from white to pink to red. Animals such as bees and hummingbirds help these plants reproduce by transferring pollen as they travel from flower to flower. Hummingbirds prefer red flowers. Bumblebees prefer pink flowers. Which population distribution of hummingbirds and bumblees would you expect to find if there were mostly pink monkey flowers in one area?

A large population of bumblebees and a few hummingbirds.

What is a common ancestor?

An animal from which two or more different species evolved

Identify which of the following could be an ecosystem disturbance. Clear cutting trees, oil spill, volcanic eruption, increase in a insect group, wildfire

Clear cutting tree, oil spill, volcanic eruption, wildfire

What proves common decent

DNA, comparative anatomy, biology, math, embryology, fossils

Genetic variation

Different types of genes in a population for an inherited characteristic

Dogs closest common ancestor are domestic cats T/F

False

What is necessary for evolution to occur?

Genetic Variation, Genetic Mutation

abiotic factors

nonliving things in an ecosystem

In which of the following situations is a population most likely to become extinct?

When an environmental change is rapid, and the population is unable to adapt to the change over a few generations.

Ecosystem disturbance

a change in environmental conditions that causes a change in the ecosystem

Ecosystem

a system made up of the interactions between the living and nonliving parts.

Ecosystem stability

factors stay more or less within a certain range and in a mostly stable condition, even as individual parts change.

Population

group of the same type of organisms

Community

multiple living things from a variety of animal and plant species.
