Answer the following question given this paragraph: Multicellular Photosynthetic Autotrophs hyphae are densely packed so it is difficult to see the individual structures when a mushroom is eaten. However, a mushroom is only a specialised reproductive part of the whole fungus. The main part of the fungi is underground in a whole web of hyphae, called a mycelium. In the mycelium, each fungal cell is separated from each other by a septum. Each fungal cell may have one or more nuclei and remains connected to the mycelium because the septa are porous, allowing cytoplasm to flow through the hyphae and fungal cell walls, made of a hard material called chitin. Some fungi do not have septa, and they appear to be large, branching, multinucleate cells. Q: A mushroom is only a specialised reproductive part of the whole fungus. the main part of the fungi is underground in a whole web of hyphae, called this? Choices: - detritus - hypothalamus - bacterium - mycelium A:
mycelium

Answer the following question given this paragraph: 20.2 Ohm's Law: Resistance and Simple Circuits What drives current? We can think of various devicessuch as batteries, generators, wall outlets, and so onwhich are necessary to maintain a current. All such devices create a potential difference and are loosely referred to as voltage sources. When a voltage source is connected to a conductor, it applies a potential difference V that creates an electric field. The electric field in turn exerts force on charges, causing current. Q: Potential differences from various voltage sources are necessary in order to create electrical fields, which result in what flow of charge? Choices: - voltage - output - wattage - current A:
current

Answer the following question given this paragraph: Population size is the number of individuals in a population. Population density is the average number of individuals per unit of area or volume. The pattern of spacing of individuals in a population may be affected by characteristics of a species or its environment. Q: What is the average number of individuals per unit of area or volume called? Choices: - crowdedness - population structure - population count - population density A:
population density
