Ques:Answer the following question given this paragraph: The entropy change is positive as the solid state changes into the liquid state. If the transition went from the liquid to the solid state, the numerical value for would be the same, but the sign would be reversed since we are going from a less ordered to a more ordered situation. Q: The entropy change is positive as the solid state changes into which state? Choices: - mixture - gas - chemical - liquid A:

Ans:liquid

Ques:Answer the following question given this paragraph: Mitosis vs. Meiosis Comparison. Mitosis produces two diploid daughter cells, genetically identical to the parent cell. Meiosis produces four haploid daughter cells, each genetically unique. See How Cells Divide: Mitosis vs. Meiosis at http://www. pbs. org/wgbh/nova/miracle/divide. html for an animation comparing the two processes. Q: What process produces four haploid daughter cells, each genetically unique? Choices: - electrolysis - budding - mitosis - meiosis A:

Ans:meiosis

Ques:Answer the following question given this paragraph: Figure 29.3 Graphs of blackbody radiation (from an ideal radiator) at three different radiator temperatures. The intensity or rate of radiation emission increases dramatically with temperature, and the peak of the spectrum shifts toward the visible and ultraviolet parts of the spectrum. The shape of the spectrum cannot be described with classical physics. Q: The intensity or rate of radiation emission _________ with temperature? Choices: - randomly fluctuates - decreases - does not vary - increases A:

Ans:increases

Ques:Answer the following question given this paragraph: that have taken place during this time. There are however, areas of knowledge and human experience that the methods of science cannot be applied to. These include such things as answering purely moral questions, aesthetic questions, or what can be generally categorized as spiritual questions. Science has cannot investigate these areas because they are outside the realm of material phenomena, the phenomena of matter and energy, and cannot be observed and measured. The scientific method is a method of research with defined steps that include experiments and careful observation. The steps of the scientific method will be examined in detail later, but one of the most important aspects of this method is the testing of hypotheses. A hypothesis is a suggested explanation for an event, which can be tested. Hypotheses, or tentative explanations, are generally produced within the context of a scientific theory. A scientific theory is a generally accepted, thoroughly tested and confirmed explanation for a set of observations or phenomena. Scientific theory is the foundation of scientific knowledge. In addition, in many scientific disciplines (less so in biology) there are scientific laws, often expressed in mathematical formulas, which describe how elements of nature will behave under certain specific conditions. There is not an evolution of hypotheses through theories to laws as if they represented some increase in certainty about the world. Hypotheses are the day-to-day material that scientists work with and they are developed within the context of theories. Laws are concise descriptions of parts of the world that are amenable to formulaic or mathematical description. Natural Sciences What would you expect to see in a museum of natural sciences? Frogs? Plants? Dinosaur skeletons? Exhibits about how the brain functions? A planetarium? Gems and minerals? Or maybe all of the above? Science includes such diverse fields as astronomy, biology, computer sciences, geology, logic, physics, chemistry, and mathematics (Figure... Q: The scientific method is a method of research with defined steps that include experiments and careful what? Choices: - discovery - estimation - consideration - observation A:

Ans:
