BSC 10 05 MIDTERM REVIEW EXAM 2024-2025 To arrive at dependable conclusions regarding pillbug preferences, apply the scientific method. Prior to starting a scientific investigation, you ought to: - ANSWER - formulate a hypothesis Select a course of action What is the number of phases in the scientific method? - REPLY 4 Sort the four stages of the scientific process into the following order: ANSWER 1. premise 2. trial 3. examination 4. report The foundation of a/an __________ should be observations and prior information, according to the ANSWER hypothesis. ANSWER 1: Match the action to the relevant stage of the scientific method. analysis: create graphs, assess the theory 2. experiment: implement the plan and gather data 3. report: record outcomes 4. formulating an idea and coming up with a plan The lab concludes that developing a sound hypothesis is considerably less significant than: - ANSWER developing an effective plan to test the hypothesis The scientific method involves two different kinds of variables. They are: - Independent and dependent on the answer A hypothesis needs to be: - Testable by answers The ________ variable, which is dependent on the answer, is the variable you will measure in an experiment. As per your lab, the ________ variable, which is ANSWER independent, is the variable that you modify during the experiment (the one that "varies"). It is not necessary for you to stop conducting your experiment in order to record your data. Following the experiment, you can go back and estimate the values. - False answer The most crucial part of the scientific method is, by far, to ensure that your hypothesis produces a true statement. ANSWER false You will implement the plan you created to test the hypothesis —the ANSWER experiment —during the _______ phase. To determine whether your hypothesis is supported —that is, whether it is true —you should use the graph created from your data. When developing a hypothesis, it's critical to ascertain its breadth before focusing on four or five variables. ANSWER false Science is the process of formulating a theory and ANSWER testing it. ANSWER analyse your data and plot it on a graph during the analysis step. It is crucial that you graph your data with the independent variable on the x-axis. It's crucial to ANSWER plot the dependent variable on the y-axis when charting your data. A scientific experiment is deemed a total failure if the hypothesis is unsupported, and it must be repeated until a desired result is obtained. ANSWER false After entering the data into the notebook for the pillbug experiment, you have to ANSWER compute average values and then visualise the values on a graph. The outcome you will study should be taken into account (check all that apply) while deciding on the scope of an experiment. The variable component The scientific method is exclusively applied by scientists. ANSWER false Consider that you want to compare the two diets that tadpoles grown in a lab will be fed. One diet consists of fish dishes with a meat base, while the other is the conventional diet of boiled lettuce. You want to find out if the tadpoles' average weight would rise in correlation with a diet high in meat. You maintain the same levels of all other variables in your experiment, including temperature, pH, tadpole density per pan, and food quantity. The tadpoles' diet is the only thing that separates the experimental and control groups. In the tadpole food experiment, what is the independent variable? - REPLY diet Consider that you want to compare the two diets that tadpoles grown in a lab will be fed. One diet consists of fish dishes with a meat base, while the other is the conventional diet of boiled lettuce. You want to find out if the tadpoles' average weight would rise in correlation with a diet high in meat. You maintain the same levels of all other variables in your experiment, including temperature, pH, tadpole density per pan, and food quantity. The tadpoles' diet is the only thing that separates the experimental and control groups. In the tadpole food experiment, what is the dependent variable? - ANSWER tadpole size Consider that you want to compare the two diets that tadpoles grown in a lab will be fed. One diet consists of fish dishes with a meat base, while the other is the conventional diet of boiled lettuce. You want to find out if the tadpoles' average weight would rise in correlation with a diet high in meat. You maintain the same levels of all other variables in your experiment, including temperature, pH, tadpole density per pan, and food quantity. The tadpoles' diet is the only thing that separates the experimental and control groups. Which theory fits this tadpole
