8751981603Why is Biology a Science?Biology is a science since it takes care to interpret the nature, according to the scientific method, which establishes the resolution of hypotheses raised by the researcher, by means of using different techniques for the creation of representative models of nature.34
8751981604Distinguish between Inductive and Deductive ReasoningInductive reasoning derives generalizations from specific cases and deductive reasoning predicts specific outcomes from general premises.35

8751981606What is the difference between hypothesis, theory and law?The Difference between a Hypothesis a Theory and a Law there are very distinct. A hypothesis is a statement that can be tested. A theory is a statement that has not been tested. A Law is a statement that is relevant and is true.37
8751981607What is the difference between observational and experimental investigations?Observational investigations do not manipulate data38
8751981608What is the difference between qualitative and quantitative data?Quantitative data includes recorded measurements which can be organized into tables or graphs and qualitative data would include observations39
8751981609What is the relationship between the conclusion and the hypothesis?The conclusion is a statement about the experiment's results. As a report of your data, it can't be considered wrong even if the results don't support your hypothesis. You have learned that your hypothesis does not answer your original research question.40

8751981613What is the Theory of Natural Selection?A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits.44
8751981614How do we distinguish between results(data) and conclusions?Results are measurable data and a conclusion is a report about what you learned based on w the results45
8751981615Concept 1.2: Why is evolution considered the core theme of biology?Evolution accounts for the unity and diversity of life and it explains the most fundamental aspects of all life on earth. It accounts for the common features shared by all forms of life due to the descent from a common ancestor.46
8751981616Concept 1.3: How could natural selection have led to the evolution of adaptations such as the thick, water conserving leaves of the mother of pearl plant?Ancestors of this plant may have exhibited variation in how well their leaves conserved water. Because not much soil is present in the crevices where these plants are found, the variant plans that could conserve water may hav survived better and been able to produce more offspring.47

8751981618What is the molecule that can account for both the unity and the diversity of life?DNA49

8751981620How would you define a Eukaryotic cell?A eukaryotic cell has membrane-enclosed organelles, the largest of which is usually the nucleus51
8751981621How would you define a prokaryotic cell?A prokaryotic cell is simpler and usually smaller, and does not contain a nucleus or other membrane-enclosed organelles52
