input with options: 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? A:
OPTIONS:
- discovery
- estimation
- consideration
- observation
output: observation

Q: Answer the following question given this paragraph: The population is an important unit in ecology as well as other biological sciences. How is a population defined, and what are the strengths and weaknesses of this definition? Are there some species that at certain times or places are not in populations?. Q: During interphase, the cell undergoes normal growth processes while also preparing for what, by accumulating energy and building blocks of dna? A:

OPTIONS:
- proteins division
- chromosome division
- technology division
- cell division

A: cell division

Answer the following question given this paragraph: Unfortunately, maternal mt(DNA)is susceptible to mutations which are a cause of inherited disease, such as breast cancer. Although, it is important to note that most mutations do not lead to defected mtDNA. Heteroplasmy is the presence of a mixture of more than one type of mtDNA. Most people have homoplasmic cells, meaning that their cells contain only normal, undefected mtDNA. However, people with both normal, undefected mtDNA and not normal, defected mtDNA, may inherit mitochondrial diseases. The ultimate condition leading to disease is when the proportion of mutant mtDNA reaches a threshold, after which the cell can no longer cope, resulting in disease. This threshold varies among different tissues and different mutations. Q: What increases the chances of someone inheriting a mitochondrial disease? A:
OPTIONS:
- presence of defect transgenic and defect mtdna
- presence of defect transgenic and undefected mtdna
- presence of defect ornithopods and undefected mtdna
- presence of defect mtdna and undefected mtdna
presence of defect mtdna and undefected mtdna
