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...

Answer the following question given this paragraph: Alkenes can react with halogens to form dihalides. Q: Alkenes react with what to form dihalides? Choices: - antioxidants - amines - oxides - halogens A:
halogens
Q: Answer the following question given this paragraph: A solid is a form of matter that has a definite shape and volume. The shape of a solid does not change if it is transferred from one container to another. The particles of a solid are packed tightly together in fixed positions, usually in an orderly arrangement. Solids are almost completely incompressible, meaning that solids cannot be squeezed into a smaller volume. When a solid is heated or cooled, it expands or contracts only slightly. Q: What is a form of matter that has a definite shape and volume? Choices: - plasma - gas - liquid - solid A:
A: solid
Question: Answer the following question given this paragraph: The explosion of nitroglycerin releases large volumes of gases and is very exothermic. Q: The explosion of nitroglycerin, which releases large volumes of gases, is what type of reaction? Choices: - energetic - exponential - endothermic - exothermic A:
Answer: exothermic

Answer the following question given this paragraph: Symbiosis describes a close and long-term relationship between different species. At least one species will benefit in a symbiotic relationship. These relationships are often necessary for the survival of one or both organisms. There are three types of symbiotic relationships: mutualism, communalism, and parasitism. Q: What are the three types of symbiotic relationships? Choices: - pledgism, truism, greenism - symbiosis , communalism , parasitism - altruism, conservatism, communalism - mutualism, communalism, parasitism A:
**Answer**
mutualism, communalism, parasitism
