Answer the following question given this paragraph: Biodiversity, Species Richness, and Relative Species Abundance Biodiversity describes a community's biological complexity: it is measured by the number of different species (species richness) in a particular area and their relative abundance (species evenness). The area in question could be a habitat, a biome, or the entire biosphere. Species richness is the term that is used to describe the number of species living in a habitat or biome. Species richness varies across the globe (Figure 45.29). One factor in determining species richness is latitude, with the greatest species richness occurring in ecosystems near the equator, which often have warmer temperatures, large amounts of rainfall, and low seasonality. The lowest species richness occurs near the poles, which are much colder, drier, and thus less conducive to life in Geologic time (time since glaciations). The predictability of climate or productivity is also an important factor. Other factors influence species richness as well. For example, the study of island biogeography attempts to explain the relatively high species richness found in certain isolated island chains, including the Galapagos Islands that inspired the young Darwin. Relative species abundance is the number of individuals in a species relative to the total number of individuals in all species within a habitat, ecosystem, or biome. Foundation species often have the highest relative abundance of species. Q: In the field of biodiversity, "richness" and "abundance" are used to describe different what? Choices: - nutrients - densities - water sources - species A:
species
Answer the following question given this paragraph: Like bacteria, archaeans are important decomposers. For example, archaeans help break down sewage in waste treatment plants. As decomposers, they help recycle carbon and nitrogen. Q: Archaeans help break down sewage in waste treatment plants, so they fulfill what important role? Choices: - producers - consumers - pollenation - decomposer A:
decomposer
Q: Answer the following question given this paragraph: The deBroglie wave equations allows calculation of the wavelength of any moving object. Q: What type of equations allows calculation of the wavelength of any moving object? Choices: - fluctuations wave - disc wave - develpoment wave - debroglie wave A:
A: debroglie wave
Question: Answer the following question given this paragraph: A seismograph is a machine that records seismic waves. In the past, seismographs produced a seismogram . A seismogram is a paper record of the seismic waves the seismograph received. Seismographs have a weighted pen suspended from a stationary frame. A drum of paper is attached to the ground. As the ground shakes in an earthquake, the pen remains stationary but the drum moves beneath it. This creates the squiggly lines that make up a seismogram ( Figure below ). Q: What is used to record seismic waves? Choices: - transmitter - odometer - topometer - seismograph A:
Answer: seismograph

Answer the following question given this paragraph: Large or small numbers are expressed in scientific notation, which use powers of 10. Q: Large or small numbers are expressed in scientific notation, which use powers of this? Choices: - 2 - 4 - 16 - 10 A:
**Answer**
10
Answer the following question given this paragraph: The core is the Sun's innermost layer. The core is plasma. It has a temperature of around 15 million degrees Celsius (C). Nuclear fusion reactions create the immense temperature. In these reactions, hydrogen atoms fuse to form helium. This releases vast amounts of energy. The energy moves towards the outer layers of the Sun. Energy from the Sun's core powers most of the solar system. Q: What is the suns innermost layer called? Choices: - surface - solar - flare - core A:
core
