7B: Niles Eldredge and Stephen Jay Gould researched the lenses of the eyes of fossil trilobites of different species. In 1972 they published a paper in which they described the tendency of a species to remain the same until a sudden change in the environment causes a new related to appear. Which hypothesis was most challenged by the work of Eldredge and Gould?

7A The opossum, which is native to North America, and the kangaroo, which is native to Australia, are marsupials.

The fact that both these mammals incubate their immature offspring in a pouch provides evidence that they —

7A: The image shows part of the humerus bone in different genera of primates. Which statement is best supported by the observable structures of the different humerus bones?

Two scientists studied patterns of evolution in the fossil record. Many species they analyzed showed periods of slow changes interrupted by a period of rapid change.This pattern of periods of slow change interrupted by periods of rapid change with few, if any transitional fossils, best describes the theory of —

7A: Cetaceans are whales and their relatives. The diagram shows some fossils of cetaceans. Which statement provides the best evidence that Ambulocetus natans is an ancestor of Basilosaurus isis?

7A Three species of lizards of the genus Gallotia are found on the Canary Islands, a chain of seven volcanic islands off the west coast of Africa. The easternmost island, Lanzarote, is the oldest, while the westernmost island, El Hierro, is the youngest. The distribution of lizard species is shown on the map.

Which statement about the ancestry of the lizards from the genus Gallotia is best supported by this information?

Cross-pollination of flowers from different populations of the same species will most likely result in —

7F: Common baboons live on the savanna in breeding groups called troops. While females tend to stay with the troop, younger or less dominant males may leave to join a neighboring troop. Which of these is a likely outcome of movement by young males?

7C: The diagram shows light- and dark-colored beetles that live on a tree. Which result is most likely to occur to the beetle population due to predation over time? Select two answers.

7D: The green frog (Lithobates clamitans clamitans) is found in many parts of the United States. The table contains some information about this frog. Why does the ability to lay 1,000 to 5,000 eggs increase the fitness of the species L. clamitans clamitans?

Most animals avoid eating monarch butterflies due to their bad taste. Viceroy butterflies look very similar to the monarchs.Which of these best explains how the viceroy butterfly benefits from looking like the monarch butterfly?

White clovers, Trifolium repens, are plants that are native to Europe and Central Asia and are able to produce the poison cyanide within their cells. Skunk cabbage, Symplocarpus foetidus, is a plant that is native to eastern North America and can produce a chemical that makes it have a strong, foul odor and bitter taste. The chemicals produced by both the white clovers and skunk cabbages are adaptations that allow them to —

Green anoles are lizards that can change their skin color rapidly in response to various stimuli. This adaptation is the result of —

Why is it important to assign each organism a scientific name?

The table shows the classification of four mammals found in Texas. Based on this table, which explanation best describes why elk and fallow deer are classified in the same genus?

8B: The classification of four trees are shown in the table. Which two trees are the most closely related?

8B Many tree frog populations are threatened due to habitat loss. In an effort to promote conservation, tree frogs may be bred in captivity. A zoo acquired male and female tree frogs from two different populations. In the zoo, the tree frogs were able to successfully mate within their own population, but breeding attempts between the two populations were unsuccessful.

Based on this information, which statement correctly describes the relationship between the two populations of tree frogs?

Plants and animals belong to which domain?

Which characteristic do all organisms in Kingdoms Animalia, Protista, and Fungi have in common?

8C: Which list correctly identifies characteristics that protists share with animals? Select all that apply.

Who is most closely related to Taxidea taxus?

A phylogenetic tree based on genetic similarities is shown. Which numbered location on the phylogenetic tree identifies characteristics shared by Species B, C, and D?

Based on this phylogenetic tree, which statement is true?

Which of these animals does not have/produce an amniotic egg?

8B The diagram shows a dichotomous key and a picture of a fruit.

According to the key, the fruit comes from which species of tree?
