As red blood cells pick up carbon dioxide from tissues to be moved to the lungs, the carbon dioxide reacts with water to form carbonic acid. Carbonic acid is transported to the lungs where it is converted back to carbon dioxide and water, and the carbon dioxide can then be exhaled. Carbonic anhydrase increases the rate of production of carbonic acid from only 200 molecules of carbonic acid to 600,000 molecules being formed per hour. This increase in reaction rate is necessary for the process to be biologically useful. Carbonic anhydrase is not changes in the reaction. Carbonic anhydrase is a(n) • Pigment • Substrate • Enzyme • Reactant

Karen wants to win a blue ribbon at eh fair this year for the largest tomato plants. She would like to compare two new plant foods on her tomato plants to see if they really make the plants grow larger. Karen needs to design an experiment to see which plant food induces more growth. She has three of the same type so tomato plant, and they all receive the same amount of sunlight, water, and temperature. Karen adds plant food A to plant A, B to plant B, and lets C grow without any plant food. She measures the height of the plants every week. Plant A and B are part of which group? • Control • Variable • Data • Experiment

The NC State saltwater fish is the red drum, or channel bass, whose species name is Sciaenops ocellatus. Sciaenops is Greek for perch-like marine fish and ocellatus is Latin for eye-like colored spot, which the red drum has on its tail. Scientists believe that the spot may fake predators into attacking the red drum toward their tails instead of near their eyes, allowing the red drum to escape. What type of adaptation does this represent? • Physical • Chemical • Behavioral • All of the above

Scientists make many observations and ask many questions about the world around them. From these observations and questions come hypotheses, which are tentative explanations for observed phenomena. For a hypothesis to be scientific, it must be testable by experimentation. Which one of the following is a testable hypothesis? • Killer bees are more attracted to the color black than the color white • Dogs make better pets then cats • Talking to plants makes them feel accepted • Swans are more graceful than mallards

A student heats a beaker full of water over a low flame. While heating, the students adds 3 grams of salt that has been measured out on a tarred beam balance.

A team of researchers announces that they have cloned a human. They refuse to explain their exact method, stating that they do not want anyone to copy their work. Which represents the most likely response from the scientific community? • Their work will be accepted because scientists can usually tell from the results whether or not the method was sound • It is impossible to clone a human beings, so no one will ever believe the new research • Their work will be discounted until their method and results are confirmed in identical trials by other scientists • Scientists will believe the new research until it is disproved by other scientists

Sand dunes feature various types of vegetation like the common marram grass. When humans attempt to create or restore a dune, they often plant marram grass and other vegetation because • It helps the beach recover from pollution • It helps prevent dune erosion • It stops the tides from coming inland • That is where sea turtles lay their eggs

Hunting is one methods of wildlife management, allowing populations of some species to be reduced before they reach or exceed carrying capacity and begin to damage their environment. For instance, snow geese have exceeded their carrying capacity and begun to seriously damage the arctic and sub-arctic salt-marsh habitat that is their summer foraging ground. This prompted President Clinton to sign legislation intended to reduce the population of the geese by 50% over 5 years. However, other kinds of hunting are not intended to control animal populations. Choose the hunting scenario that is not an ecological control tool. • Animal management authorities periodically hunt populations of deer in New Jersey • Midwestern farmers often hunt coyotes hat harass their livestock • African elephants are hunted for the ivory of their trunks • Feral cat populations are hunted and killed in all urban and semi-urban areas to reduce the spread of disease
