Discussion: Referring to the hypothesis we predicted in the beginning of this experiment that under ideal conditions‚ we hypothesized that the results will eventually follow the Hardy-Weinberg expectations‚ which means the genotypes frequencies of the Drosophila melanogaster would remain constant; Therefore‚ no evolution had happened to the flies under the ideal conditions. After the chi-squared values were found in each week (table 1)‚ in the third generation where the chi-squared was found to

2 September 2014 Chapter 1 Review 1. Describe the characteristics of science. A. The characteristics of science are observations‚ search for regularities‚ process the information‚ and self-corrections. Science is based upon observations that incorporate our senses‚ or instruments that extend our senses‚ to interpret natural experiences. Science is a searh for regularities. These regularities may include observed phenomena or patterns in nature. After observations have been recorded about regularities

TOPIC III : Sociological Research Methods and Designs QUESTION : Distinguish between a hypothesis and a theory. INTRODUCTION: Sociological research refers to research conducted by social scientists which follows a systematic plan. The emphasis is on the collection of data that is valid reliable and dependable. There are two broad traditions that have been highlighted in the study of sociology which are positivism and interpretivism.

Q 1. In this practical exercise you will be using biuret reagent. Why is biuret reagent used in this practical? The biuret reagent is used to assess the concentration of the protein because peptide bonds occur with the same frequency per amino acid in the peptide. The intensity of the colour‚ and therefore the absorption‚ is directly proportional to the protein concentration. Q 2. What is the experimental reason for constructing a standard curve? Multiple samples with known properties

WORKSHEET FOR SCIENTIFIC METHOD: PLANTS LAB 1 1. Write your hypothesis (should be in a complete sentence and describe what exactly is being tested). I think that the test group with the soap in it will cause the plant to die while the one that is not being affected by the soap continues to grow. 2. Describe your control group and your experimental group with regards to what variables were used in each. Control Group: The group of flowers that will not be receiving any detergent/soap

2 Abstract The abstract is a brief summary of the entire proposal‚ typically ranging from 150 to 250 words. It is different from a thesis statement in that the abstract summarizes the entire proposal‚ not just mentioning the study’s purpose or hypothesis. Therefore‚ the abstract should outline the proposal’s major headings: the research question‚ theoretical framework‚ research design‚ sampling method‚ instrumentation‚ and data and analysis procedures. A good abstract accurately reflects the content

begins the body of the research report. Center the title at the top of the page. Start the introduction with a statement of the research problem. Then‚ cite the relevant research. The literature review provides a context and rationale for the hypothesis that is under investigation. Mainly cite primary sources. Paraphrase rather than quoting directly from the past literature and document the source by listing the authors name and year of publication in parenthesis. When documenting‚ you can use

Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. 3. What would your experimental approach be to test this hypothesis? 4. What would be the independent and dependent variables? 5. What would be your control? 6. What type of graph would be

experiment to test a hypothesis. The number of steps of the scientific method isn’t standard. Some texts and instructors break up the scientific method into more or fewer steps. Some people start listing steps with the hypothesis‚ but since a hypothesis is based on observations (even if they aren’t formal)‚ the hypothesis usually is considered to be the second step. Here are the usual steps of the scientific method. Scientific Method Step 1: Make Observations You may think the hypothesis is the start of

observe ring the plant species called Kentucky Blue Grass. In this observation I will show how changes in the weather can affect the population of the grass. I will also explain how this may have some effect on Global Warming as well. Hypothesis: My hypothesis of this lab was that if you have more rain the population of the grass will greatly increase. Along with decent to great weather to help the grass grows and become healthy. Methods: There were three different times that I changed the
