The middle layer is volcanic ash. The top layer is mud stone (shale) with fossils of a different species of reptile. The fossil evidence supports which hypothesis about the extinction of the older reptile species? Question 9 A. The older reptile species went extinct because sea levels rose and flooded its habitat. B. The older reptile species went extinct because a predator was introduced into the environment. C. The older reptile species went extinct because it could not compete with the younger reptile species. D.

The diagrams below show the digestive systems of an earthworm and a bird. ohio3-8.success-ode-state-oh-us.info/practicetest/customizeview.aspx?testid=202741&printresults=true&viewall=true 3/12
4 Earthworms and birds have strong muscular gizzards. The gizzard grinds food into small bits before it passes on to the intestine. Mammals, in contrast, do not have gizzards. Why do earthworms and birds need to have gizzards but mammals do not? A. Earthworms and birds are not equipped to chew food. B. Earthworms and birds eat food that is difficult to digest. C. Earthworms and birds have intestines that work inefficiently. D. Earthworms and birds do not have stomachs to mix moistened food. Question 10 Use the information and diagram below to answer question #. Male mussels release sperm into the water. Female mussels take the sperm into their gill chambers where fertilization occurs. Young mussel larvae are released into the water where they float freely until they attach to the gill of a host fish. After a few weeks, they reach the juvenile stage and drop off. After the juvenile drops off the fish gill, it burrows into the river bed and begins the life cycle all over again. The parasitic behavior of the larvae benefits the mussel in two ways. One benefit is that the fish provides nutrition for the larvae when they are attached to its gill. What is the second way this behavior enhances the survival of the mussel species? ohio3-8.success-ode-state-oh-us.info/practicetest/customizeview.aspx?testid=202741&printresults=true&viewall=true 4/12
5 A. The large size of the fish provides the mussel larvae with plenty of room to grow. B. The parasitism increases the opportunity for the mussels to mate with other mussel species. C. The mobility of the fish spreads the mussels to areas they would otherwise be unable to reach. D. The location of the larvae on the gills of fish reduces the exposure of the larvae to oxygen-rich water. Question 11 Which is an example of a group of cells with a common structure and function? A. stomach B. muscle tissue C. mitochondria D. digestive system Question 12 Use the following pictures to answer question #. ohio3-8.success-ode-state-oh-us.info/practicetest/customizeview.aspx?testid=202741&printresults=true&viewall=true 5/12
6 The reproductive success of an organism depends in part on the ability of the organism to survive. How does the physical appearance of these organisms help them survive? A. Their physical appearance helps them find a habitat. B. Their physical appearance helps them resist parasites. C. Their physical appearance helps them avoid predators. D. Their physical appearance helps them defend a territory. Question 13 Termites eat wood but cannot digest it. Protozoans live in the termites stomachs and use enzymes to break down the wood. The digested wood provides nutrition for both the termites and the protozoans. What type of relationship is this? A. mutualism B. parasitism C. predation D. commensalism Question 14 Use the diagrams and information below to answer question #. Monte Bolca is located high in the mountains of northern Italy. This site is one of the world s largest deposits of coral reef fish fossils. There are fossils of more than 160 fish species dating back 49 million years. These fossils provide evidence of the environment in which the coral fish lived and died. Which statement is consistent with this evidence and explains how ancient coral reef fossils can be found high in the mountains far from any sea? A. A huge tidal wave pushed marine life up into the mountains. B. Prehistoric man carried fish into the mountains from the sea. C. Fish were thrown into the mountains by a tremendous volcanic explosion. D. Land that was uplifted to form the mountains was once covered by the sea.

8 In your Answer Document, describe how the new plant compares genetically with the parent plant. Describe one advantage that asexual reproduction might offer the strawberry plant. (2 points) Question 18 Use the information below to answer question #. Fossils of the Coelacanth (sø' lœkanth') fish occur in the fossil record from 410 to 65 million years ago. The lack of more recent fossils led scientists to conclude that the fish went extinct along with the dinosaurs. In 1938, a fisherman caught a living Coelacanth. More than 200 of them have been caught on the deep reefs in the Indian Ocean. This fish has been called a living fossil because its body plan is nearly identical to the 400-million-year-old fossils. This structural similarity, as evidenced by the fossil record, supports which statement? A. The environment of the deep sea has changed little over millions of years. B. The amount of salt in the deep sea has varied greatly over millions of years. C. The oceans have completely dried up multiple times during the past 400 million years. D. The oceans have been continuously repopulated by freshwater fish species over millions of years. Question 19 What is the role of the mitochondrion in cells? A. It converts sunlight to energy. B. It controls all functions of the cell. C. It transports water throughout the cell. D. It breaks down sugar to release energy.

A. chloroplast and mitochondrion B. mitochondrion and cell wall C. chloroplast and nucleus D. nucleus and cell wall Question 24 Use the following information and food web to answer question 38. Sea otters are marine mammals that live in giant kelp forests along the Pacific coast of North America. Sea otters have an important role in the food web of this ecosystem. When sea otters are removed from the giant kelp forest, the kelp also begins to disappear. ohio3-8.success-ode-state-oh-us.info/practicetest/customizeview.aspx?testid=202741&printresults=true&viewall=true 9/12
10 In your Answer Document, explain why the absence of sea otters would lead to a decrease in the giant kelp. Then, choose another organism in the food web and explain why the decreasing amount of giant kelp would affect that organism. (2 points) Question 25 Aphids are a common plant-pest insect.

What advantage does the switch to sexual reproduction give the aphids? A. Sexual reproduction maintains a constant level of variation in the population and requires less energy. B. Sexual reproduction decreases variation in the population and prevents the spread of harmful mutations. C. Sexual reproduction increases variation in the population and provides for adaptability in a changing environment. D. Sexual reproduction produces individuals that are clones and allows rapid population growth under stable environmental conditions. Question 26 Aphids, ants and plants interact with one another through symbiotic relationships. Aphids are small insects that poke holes in plants and suck out sap. Aphids may cause the plant s leaves to wilt and curl. Ants protect aphids and eat the sugary liquid that aphids produce. In your Answer Document, choose two of the organisms in this symbiosis.
