A forest of trees with white bark is home to a species of gray moth and to birds which prey on them. Pollution made the bark of the trees go black. Several years later most of the moths had wings that were

This diagram represents one possible evolutionary change that could have led lobe-finned fish to develop into the first amphibians. Amphibians are animals that live on land some of their life.

This change from fins on the lobe finned fish to legs and feet on the early amphibian is most likely due to

Which statement correctly interprets the importance of structures in biological classification system?

On a small isolated island, there is a single species of seed-eating birds. Individual birds are able to eat seeds that are within 2 mm (larger or smaller) of their beak depth. The distribution of individuals is shown in the chart.

A long drought caused the plant species that produce seeds between 3-9 mm in size to go extinct. What does the Theory of Natural Selection predict will happen to the population of seed-eating birds over time?

This photograph shows a recently discovered all-black penguin chick and several typical black and white chicks.

A farmer growing potatoes noticed aphids, a type of insect, feeding on the plants. An insecticide was sprayed on the plants several times over a two year period. The graph represents sample of 3 different generations of insecticide resistant and nonresistant aphids over this time period.

The resistance gene was present in the aphid population as a result of

In August 2010, the Asian clam was discovered in Lake George. It is not native to that area. A single clam can reproduce and release hundreds of offspring in a day. Fish and crayfish eat the clams but cannot keep pace with the rate at which the clams reproduce. The introduction of the Asian clam into Lake George is

The ozone layer of Earth's atmosphere helps to filter UV radiation. As the ozone layer is depleted, more UV radiation reaches Earth's surface. This increase may be harmful because it can directly cause

The graph shows the masses of different types of plants found in the Adirondack Mountains after a forest fire. The time shown in the graph is most likely measure in

In this diagram letters A through E represent organisms carrying on a process at that particular point in the cycle. Letter B represents

Rabbits produce large numbers of offspring during each reproductive season, yet the number of rabbits within a given population changes very little from year to year. The stability of the population size is most likely a result of

This best represents

The dotted line on the accompanying graph represents the potential size of a population based on its reproductive capacity. The solid line on this graph represents the actual size of the population.

Which statement best explains why the actual population growth is less than the potential population growth?

Which level contains organisms that carry out autotrophic nutrition?

Based on the modern system of classification, unicellular organisms that contain both chloroplasts and flagella would be classified as

The table gives both the common and scientific names of five New York State vertebrates. Which two are most closely related?

Since 1980, the vulture population in India has declined from 40 million to 60 thousand due to poisoning by a pain reliever used in cattle. If only 1% of the cattle carcasses fed on by vultures are animals that have been treated with the drug, it can lead to a drastic decline in the vulture population. The grim picture is that over 10% found to contain this drug.

Vultures feed exclusively on the carcasses of dead animals. This helps to prevent the spread of diseases such as rabies and anthrax among wildlife, stock, and humans. Without as many vultures, other scavengers such as dogs have moved in and taken advantage of the newly available food. The abundance of these other scavengers has led to an increase in the number of human rabies and and outbreak in TB, anthrax and other diseases. These diseases are not spread to humans by vultures.

The best explanation for the increase in rabies, anthrax, and other diseases in humans is that the

If the population of hawks in this area increases, their prey populations might decrease. Later, with fewer prey, the hawk population might decrease. This is an example of

Which statement describes a situation that leads to stability in an ecosystem?

For many years, scientists debated whether viruses should be considered living organisms. Which statement could a scientist use to support the position that viruses are NOT living?

What inference can be made from the information in this diagram?

Base your answers to the question on this diagram. The diagram shows an interpretation of relationships based on evolutionary theory. The letters represent different species. The diagram indicates that a common ancestor for species C and E is species

A particular species of shark normally reproduces sexually. In captivity, it was found the female could also reproduce asexually. One NEGATIVE result from asexual reproduction is

In cabbage butterflies, white color (W) is dominant and yellow colors (w) is recessive. If a pure white cabbage butterfly mates with a yellow cabbage butterfly, all the resulting (F1) butterflies are heterozygous white. Which cross represents the genotypes of the parent generation?

When Mendel was experimenting with pea plants, he noted that the traits for seed color and plant height were inherited separately. This observation most directly contributed to an understanding of

A partial food web for organisms in Yellowstone National Park is shown. Which process do the animals in the food web use to convert energy from food into ATP?

The sorting and recombining of genes during meiosis and fertilization usually leads to the production of
