Answer the following question given this paragraph: Birds may be specialists or generalists in terms of what they eat. Generalists are organisms that eat many different types of food. Birds that are generalists include the red-winged blackbird in Figure below . It has a basic beak that can eat many different foods. Red-winged blackbirds are omnivores. They may eat a wide variety of seeds as well as insects and other small animals such as snails and frogs. Q: What are organisms called, like the red-winged blackbird, that eat many different types of food? Choices: - omniverous - specalist - carniverous - generalists A:
generalists
Answer the following question given this paragraph: Gas Laws and Air Composition Gas molecules exert force on the surfaces with which they are in contact; this force is called pressure. In natural systems, gases are normally present as a mixture of different types of molecules. For example, the atmosphere consists of oxygen, nitrogen, carbon dioxide, and other gaseous molecules, and this gaseous mixture exerts a certain pressure referred to as atmospheric pressure (Table 22.2). Partial pressure (Px) is the pressure of a single type of gas in a mixture of gases. For example, in the atmosphere, oxygen exerts a partial pressure, and nitrogen exerts another partial pressure, independent of the partial pressure of oxygen (Figure 22.21). Total pressure is the sum of all the partial pressures of a gaseous mixture. Dalton's law describes the behavior of nonreactive gases in a gaseous mixture and states that a specific gas type in a mixture exerts its own pressure; thus, the total pressure exerted by a mixture of gases is the sum of the partial pressures of the gases in the mixture. Q: The atmosphere consists of oxygen, nitrogen, carbon dioxide, which exerts a certain pressure referred to as what? Choices: - gravity pressure - tidal pressure - nitrogen pressure - atmospheric pressure A:
atmospheric pressure
Q: Answer the following question given this paragraph: 16.4 The Simple Pendulum A mass m suspended by a wire of length L is a simple pendulum and undergoes simple harmonic motion for amplitudes less than about 15. The period of a simple pendulum is. Q: A mass suspended by a wire is a simple type of what and undergoes simple harmonic motion for amplitudes less than about 15 degrees? Choices: - gravity - variation - weight - pendulum A:
A: pendulum
Question: Answer the following question given this paragraph: Oxygen is just one substance transported by the blood. The blood also transports nutrients such as glucose. Q: Both oxygen and glucose are transported within the body via what? Choices: - bone - heart - marrow - blood A:
Answer: blood

Answer the following question given this paragraph: Pure elements with a high metallic character, meaning those that have chemical properties most similar to properties of metals, are generally very reactive. Metals tend to lose electrons in chemical reactions, as indicated by their low ionization energies. Within a compound, metal atoms have a relatively low attraction to shared electrons, as indicated by their low electronegativity values. By following the trend summary in Figure below , you can see that the most reactive metals would reside in the lower left portion of the periodic table. The most reactive metal that occurs naturally in reasonable quantities is cesium, which is always found in nature as a compound, never as a free element. It reacts explosively with water and will ignite spontaneously in air. Francium is below cesium in the alkali metal group, but it is so rare that many of its properties have never even been observed. Q: Exemplified by cesium, which ignites spontaneously in air, pure elements with a high metallic character tend to be very what? Choices: - radiactive - inactive - proactive - reactive A:
**Answer**
reactive

Answer the following question given this paragraph: CHAPTER SUMMARY 31.1 Nutritional Requirements of Plants Plants can absorb inorganic nutrients and water through their root system, and carbon dioxide from the environment. The combination of organic compounds, along with water, carbon dioxide, and sunlight, produce the energy that allows plants to grow. Inorganic compounds form the majority of the soil solution. Plants access water though the soil. Water is absorbed by the plant root, transports nutrients throughout the plant, and maintains the structure of the plant. Essential elements are indispensable elements for plant growth. They are divided into macronutrients and micronutrients. The macronutrients plants require are carbon, nitrogen, hydrogen, oxygen, phosphorus, potassium, calcium, magnesium, and sulfur. Important micronutrients include iron, manganese, boron, molybdenum, copper, zinc, chlorine, nickel, cobalt, silicon and sodium. Q: Plants can absorb inorganic nutrients and water through their root system, and what gas from the environment? Choices: - hydrogen dioxide - nitrogen dioxide - chemical dioxide - carbon dioxide A:
(A).
carbon dioxide
