Item 1 A turtle is sunning itself on a log. As a person approaches to get a better look, the turtle draws its head into its shell. Which characteristic of life is this an example of? reproduction heredity cellular organization response  Item 2 A female wolf with a short, curved tail mates and has offspring, which also have short, curved tails. Which characteristic of life is this an example of? metabolism movement heredity  growth and development Item 3 A large grocery chain plans to build a new store on a local woodlot. The building plans show a parking lot in the same location as a springtime vernal pool. How might the new store and its parking lot affect the salamanders that live in the woodlot? They would have no place to mate and lay their eggs.  It would provide new habitat for the salamanders. It would have no effect on their population. They would have no water to drink. Item 4 Which choice shows the ecological levels of organization from simplest to most complex? community, population, ecosystem, biome population, community, ecosystem, biome  biome, ecosystem, community, population population, community, biome, ecosystem Item 5 Which scenario is an example of an organism displaying evolutionary adaptations that help it survive and reproduce? A female polar bear gives birth during the Arctic summer when the largest number of predators are active. A mother sea turtle lays her eggs in the surf during low tide.  A skunk gives birth in the fall as food becomes scarce. The female salamander lays several masses of 7 to 40 eggs about 6 inches below the water's surface.  Item 1 Life would cease to exist without energy from which source? the sun  electricity chemicals water Item 2 Which process is the total of all the chemical reactions in an organism? migration metabolism  respiration homeostasis Item 3 Some types of aquatic frogs bury themselves in the mud and spend the winter hibernating at the bottom of lakes and ponds. Which characteristic of life does this behavior represent? heredity growth and development metabolism response  Item 4 How does sweating during exercise help maintain homeostasis? It regulates transport between cells. It regulates water concentration in the cells. It regulates body temperature.  It regulates ion concentrations in the cells. Item 5 Which statement about unicellular organisms is correct? Unicellular organisms must work together with other cells to carry out life functions. Unicellular organisms carry out all life processes within their one cell.  Unicellular organisms are unable to maintain homeostasis. Unicellular organisms are unable to reproduce. Item 1 Which question could a scientist seek to answer by using scientific methods? Does the tail length of a male sparrow influence the female's choice of mate?  How did life begin? What are the boundaries of the universe? Will there ever be a cure for cancer? Item 2 Which choice shows the steps of the scientific method in the correct order? make observations, conduct an experiment, gather and analyze data, draw conclusions, form a hypothesis form a hypothesis, conduct an experiment, make observations, gather and analyze data, draw conclusions, alter the hypothesis make observations, form a hypothesis, conduct an experiment, gather and analyze data, draw conclusions, alter the hypothesis  conduct an experiment, make observations, gather and analyze data Item 3 What type of variable do experiments measure? unknown variable experimental variable independent variable dependent variable  Item 4 A botanist wants to test the effect of two different fertilizers on plant growth. She plants the same plant species in each pot and measures plant height each day. Plant 1 receives Fertilizer A. Plant 2 receives Fertilizer B. Plant 3 receives no fertilizer. In this scenario, what is the dependent variable? amount of light fertilizer plant species plant height  Item 5 A botanist wants to test the effect of two different fertilizers on plant Plant Fertilizer Height (cm) growth. She plants the same plant species in each pot and measures plant height each day. 1 A 7 Plant 1 receives Fertilizer A. 2 B 12 Plant 2 receives Fertilizer B. 3 none 20 Plant 3 receives no fertilizer. After 14 days she records the data in this table and analyzes the growth of the plants. Which conclusion can she draw based on the data? Fertilizer A was more effective than Fertilizer B. The fertilizers did not help the plants grow.  The plants needed more sunlight. The fertilizers had a positive effect on plant growth. Item 1 Which statement demonstrates a scientist using scientific methods? A researcher looks for patterns in the data she has collected and organized.  A physicist discovers new information about dark matter but can not reproduce the steps he undertook in his discovery. A marine biologist uses a different technique every day to train a dolphin. A botanist places all of the seedlings in her experiment under blue lights to see if it helps them grow.  Item 2 A female digger wasp digs a hole in the ground to lay her eggs. Then, she leaves the nest to hunt and later returns to feed the larvae. Which question might a scientist ask if they want to learn more about the behavior of female digger wasps? How many eggs does she lay at a time? What type of cells does she have? How does she know where her nest is located?  What is her lifespan? Item 3 How have scientific methods changed over time? New technologies allow scientists to gain more detailed information about organisms, but scientists prefer not to use new technology and instead rely on what they have always done. Aristotle believed that answers to questions about the natural world could be obtained through reasoning, but in the 1600s the focus shifted to  evidence obtained from experiments and observations to answer questions. Aristotle believed observations and experimentation were essential to answering questions about the natural world, but in recent times, reasoning is the widely accepted method. In the past, similarities in DNA were used to classify organisms, while in recent times, simple descriptions are used to classify organisms. Item 4 Jane Goodall discovered that chimpanzees could make and use tools. How did she reach this conclusion? She observed chimpanzees in a zoo. She observed chimpanzees in a lab. She observed chimpanzees in nature.  She provided chimpanzees with tools. Item 5 How do scientists develop a hypothesis? through guessing through observation, experience, and reason  through thought experiments through researching a different topic Item 1 Fat stores energy that the body can use later. Which statement about fat cells shows how structure is related to function? Fat cells link together to form webs. Fat cells reproduce rapidly. Fat cells are expandable.  Fat cells are rigid. Item 2 Red blood cells are a component of blood. Blood flows through arteries to deliver oxygenated blood to cells and then returns to the heart through veins. Which statement about red blood cells shows how structure is related to function? Red blood cells have a sickle shape. Red blood cells are rigid. Red blood cells are shaped like smooth discs.  Red blood cells have jagged edges. Item 3 Lungs take in and release air. Which statement about lungs shows how structure is related to function? Lungs are large and rigid. Lungs are large and spongy.  Lungs are small and hollow. Lungs are small and spongy. Item 4 Which example depicts when structure no longer meets optimum function? broad flat leaves on a plant  razor sharp teeth on a shark forward facing eyes on a wolf sickle shaped red blood cells  Item 5 The stomach contains acids that break down food into smaller pieces. Which statement about the stomach shows how structure is related to function? The stomach lining hardens over time. The stomach is a large sac lined with acid-resistant tissue.  The stomach is a large sac lined with acid-sensitive tissue. The stomach lining is routinely shed and replaced.
