input: Please answer the following: Large birds are natural predators of rodents. Unfortunately, rodents consume crops in farmlands. In recent years, use of chemicals in agriculture has seen reduced number of large birds in Germany. But in some places in France farmers are cautions about using chemicals in agriculture. As a result, large bird population had been stable in France. Which country would see more crops produced, France or Germany? Hint: Predators play an important role in an ecosystem. For example, if they did not exist, then a single species could become dominant over others. Grazers on a grassland keep grass from growing out of control. Predators can be keystone species . These are species that can have a large effect on the balance of organisms in an ecosystem. For example, if all of the wolves are removed from a population, then the population of deer or rabbits may increase. If there are too many deer, then they may decrease the amount of plants or grasses in the ecosystem. Decreased levels of producers may then have a detrimental effect on the whole ecosystem. In this example, the wolves would be a keystone species.

input: Please answer the following: A scientist named Kathy walks into her office to see two neon signs plugged into the wall and hanging above her desk. Confused, she looks around to see if there's any clue as to who put them there. Seeing nobody, she flips the light switch on and walks in. Upon flipping the light switch, only the large sign lights up. Even though they are clearly both plugged in, the small sign isn't turning on. Kathy leaves her office to find someone to ask who put these random signs up in her room. Are the electrons in the large sign more or less energized than the small sign's electrons? Hint: Noble gases are also used to fill the glass tubes of lighted signs like the one in the Figure below . Although noble gases are chemically nonreactive, their electrons can be energized by sending an electric current through them. When this happens, the electrons jump to a higher energy level. When the electrons return to their original energy level, they give off energy as light. Different noble gases give off light of different colors. Neon gives off reddish-orange light, like the word "Open" in the sign below. Krypton gives off violet light and xenon gives off blue light.

input: Please answer the following: John is studying the different states of matter. Today, he has a matter in three states in front of him, state A, state B, and state C. State A is in solid state. State B is in liquid state. And, state C is in gaseous state. He needs to determine the properties of each state. Would state B's particles be more free or less free than state A's? Hint: As Figure above shows, the distance between particles is much smaller for the solid and liquid states than for the gas state. In the solid state, particles are fixed in place, while particles are more free to move in the liquid and gas states. The particles in the solid and liquid states "stick together," but in the gas state, they move freely about the container. In general, it requires energy to separate individual particles. If we want to make a solid adopt a liquid form, we can add energy in the form of heat, increasing the temperature of the substance. Conversely, if we want to convert a substance from a gas to a liquid or from a liquid to a solid, we remove energy from the system and decrease the temperature. Pressure also plays an important role in changes of state, which will be discussed later on. We will study these difference in greater detail in the chapter States of Matter.

input: Please answer the following: A new country called Zandonia has recently found itself in a crisis. They are consuming far to many natural resources. A recent study concluded that the amount of resources being consumed greatly increased over the past 3 years. This find coincides with a population boom in the region. Before the population boom the demand for natural recources was relatively stable. Which area demands more natural resources. a low population area or a high population area? Hint: Population growth, especially in developing countries, should make people think about how fast they are consuming resources. Governments around the world should seriously consider these issues. Developing nations will also increase demands on natural resources as they build more factories ( Figure below ). Improvements in technology, conservation of resources, and controls in population growth could all help to decrease the demand on natural resources.
