The 'control group' is an essential component of an experiment. This is because 1. A control group allows one to determine if a particular result is due to the experimental variable. 2. No, it's not essential in experimentation. A control group is not always necessary it depends on the experiment. 3. A control group allows for multiple variables to be tested at the same time. 4. A control group is required for the development of a prediction.
Which of the following is used when testing a prediction?a. observationsb. inductive reasoningc. controlled experimentsd. both observations and controlled experiments
Please explain What are biological concepts of this experiment, limitations and improvements…Experimental techniques & the effect of the change of variables on the results
Which of the following is not correctly linked?a. model: a representation of an object used in an experimentb. standard deviation: a form of statistical analysisc. principle: a theory that is not supported by experimental evidenced. data: the results of an experiment or observation

A controlled experiment is one that(A) proceeds slowly enough that a scientist can make carefulrecords of the results.(B) tests experimental and control groups in parallel.(C) is repeated many times to make sure the results are accurate.(D) keeps all variables constant.
At the conclusion of a good scientific studyGroup of answer choicesthe hypothesis is re-examined in light of the results and modifications are made in either the hypothesis or the experimental designthe hypothesis is proven or disproven and a theory is developedthe study is published and a guess as to why a phenomenon occured becomes facta debate typically ensues about whether the findings are legitimate
Explain how Observational Studies are different than Experiments. Be sure to describe the main purpose and goal for each of these research methods.
Design a SI modeled, detailed , yet hypothetical, biology experiment of your choice. In clear terms lay out all parameters of the experiment, including all controls and variables. Make sure that you clearly indicate where each step of the SI process applies(observation, question, hypothesis, analysis etc
