Q: What are organisms called, like the red-winged blackbird, that eat many different types of food? Read this paragraph and choose the correct option from the provided answers: 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. Choices: - omniverous - specalist - carniverous - generalists A:
**Answer**
generalists

Q: What term tells you how quickly the angle changes and can occur in either clockwise or counterclockwise directions? Read this paragraph and choose the correct option from the provided answers: The angular velocity tells you how quickly the angle changes. In more formal language, the rate of change of , the angular position, is called the angular velocity . The direction of angular velocity is either clockwise or counterclockwise. Analogously, the rate of change of is the angular acceleration . Choices: - emit velocity - shift velocity - turning velocity - angular velocity A:
**Answer**
angular velocity

Q: The temperature at which the individual ions have enough kinetic energy to overcome the attractive forces that hold them in place is called? Read this paragraph and choose the correct option from the provided answers: The Relationship between Lattice Energies and Physical Properties The magnitude of the forces that hold an ionic substance together has a dramatic effect on many of its properties. The melting point, for example, is the temperature at which the individual ions have enough kinetic energy to overcome the attractive forces that hold them in place. At the melting point, the ions can move freely, and the substance becomes a liquid. Thus melting points vary with lattice energies for ionic substances that have similar structures. The melting points of the sodium halides (Figure 8.3 "A Plot of Melting Point versus the Identity of the Halide for the Sodium Halides"), for example, decrease smoothly from NaF to NaI, following the same trend as seen for their lattice energies (Figure 8.2 "A Plot of Lattice Energy versus the Identity of the Halide for the Lithium, Sodium, and Potassium Halides"). Similarly, the melting point of MgO is 2825C, compared with 996C for NaF, reflecting the higher lattice energies associated with higher charges on the ions. In fact, because of its high melting point, MgO is used as an electrical insulator in heating elements for electric stoves. Figure 8.3 A Plot of Melting Point versus the Identity of the Halide for the Sodium Halides. Choices: - occurring point - boiling point - last point - melting point A:
**Answer**
melting point

Q: The sternum and 12 pairs of ribs with their costal cartilages make up what? Read this paragraph and choose the correct option from the provided answers: Figure 7.32 Thoracic Cage The thoracic cage is formed by the (a) sternum and (b) 12 pairs of ribs with their costal cartilages. The ribs are anchored posteriorly to the 12 thoracic vertebrae. The sternum consists of the manubrium, body, and xiphoid process. The ribs are classified as true ribs (17) and false ribs (812). The last two pairs of false ribs are also known as floating ribs (1112). Choices: - chest cage - the core - heart cage - thoracic cage A:
**Answer**
thoracic cage
