Answer the following question given this paragraph: When gas particles heat up and gain energy, they move faster. This increases their collisions with each other and their container, causing greater pressure. Q: When gas particles heat up and gain energy, what do they do? Choices: - go up - stop - move slower - move faster A:
move faster

Answer the following question given this paragraph: The speed of a wave is a product of its wavelength and frequency. Because the speed of electromagnetic waves through space is constant, the wavelength or frequency of an electromagnetic wave can be calculated if the other value is known. Q: The speed of a wave is a product of its wavelength and what else? Choices: - voltage - density - magnitude - frequency A:
frequency

Answer the following question given this paragraph: 18.2 Formation of New Species Speciation occurs along two main pathways: geographic separation (allopatric speciation) and through mechanisms that occur within a shared habitat (sympatric speciation). Both pathways isolate a population reproductively in some form. Mechanisms of reproductive isolation act as barriers between closely related species, enabling them to diverge and exist as genetically independent species. Prezygotic barriers block reproduction prior to formation of a zygote, whereas postzygotic barriers block reproduction after fertilization occurs. For a new species to develop, something must cause a breach in the reproductive barriers. Sympatric speciation can occur through errors in meiosis that form gametes with extra chromosomes (polyploidy). Autopolyploidy occurs within a single species, whereas allopolyploidy occurs between closely related species. Q: Both pathways that isolate a population reproductively in some form, allopatric and sympatric describe what, which means the creation of new species? Choices: - accumulation - extinction - bacterial - speciation A:
speciation

Answer the following question given this paragraph: Slime molds are fungus-like protists that grow as slimy masses on decaying matter. They are commonly found on items such as rotting logs. Q: Slime molds are fungus-like protists that grow as slimy masses on what? Choices: - recycled matter - food matter - dark matter - decaying matter A:
decaying matter
