Answer the following question given this paragraph: Not all archaeans live in extreme conditions. In fact, archaeans are now known to live just about everywhere on Earth. They make up as much as 20 percent of Earth's total mass of living things. Q: What kingdom of organisms constitutes up to 20 percent of all living things on earth in mass? Choices: - protists - sporozoans - vertebrates - archaeans A:
archaeans
Answer the following question given this paragraph: The molar mass of any substance is the mass in grams of one mole of representative particles of that substance. The representative particles can be atoms, molecules, or formula units of ionic compounds. This relationship is frequently used in the laboratory. Suppose that for a certain experiment you need 3.00 moles of calcium chloride (CaCl 2 ). Since calcium chloride is a solid, it would be convenient to use a balance to measure the mass that is needed. The molar mass of CaCl 2 is 110.98 g/mol. The conversion factor that can be used is then based on the equality that 1 mol = 110.98 g CaCl 2 . Dimensional analysis will allow you to calculate the mass of CaCl 2 that you should measure. Q: Who first proposed that earth is a magnet? Choices: - Albert Einstein - Isaac Newton - Marconi - william gilbert A:
william gilbert
Q: Answer the following question given this paragraph: The pistil is the female reproductive structure of a flower. It consists of a stigma, style, and ovary. The stigma is raised and sticky to help it catch pollen. The style supports the stigma and connects it to the ovary, which contains the egg. Petals attract pollinators to the flower. Petals are often brightly colored so pollinators will notice them. Q: What is the female reproductive structure of a flower called? Choices: - the stamen - the pollinator - the stigma - the pistil A:
A: the pistil
Question: Answer the following question given this paragraph: Carrying this one step further, we note that the slope of a velocity versus time graph is acceleration. Slope is rise divided by run; on a v vs. t graph, rise = change in velocity v and run = change in time t . The Slope of v vs. t The slope of a graph of velocity. Q: Rise divided by run is called what? Choices: - hill - steep - mound - slope A:
Answer: slope
