Purpose: The purpose of this lab experiment is to see if this particular type of fruit which in this case is a strawberry contains DNA. Using materials such as a Ziploc bag to help keep the entire strawberry in one place while it gets smashed and test tube to help better see the DNA and break down of the liquid in the left over strawberry sediments.…
In an experiment, this variable is expected to be affected by the manipulation. Independent variable…
Brandon Schmetterer 3-13-15 Biology labs DNA Extraction Lab DNA is extracted from humans for genetic testing, for body identification, and for analysis of forensic evidence. The first step of DNA extraction is to take cheek cells from the test subject. Next, the cells must be burst open in order to release DNA. Third, DNA is separated from protein and debris. Lastly, the DNA must be isolated.…
For the following experiments identify the three variables for each experiment and what the experimental and control groups should look like.…
statement of problem: in this lab we will determine how enzymes affect the amount of apple juice produced from applesauce we will test pectinase cellulase and a combination of both of of the enzymes and then finally we will use water ( which will be used as the controlled variable).…
The independent and dependent variable for this experiment was the male fruit fly and the female fruit fly and the off springs. The controlled variables in this experiment were temperature, media, yeast, to much of the yeast would kill the fruit fly’s so the class had to make sure that to much was not poured into the vials. this had to be controlled well. 6- 10 ten grains of yeast with water and media. A change in temperature could also tamper with the experiment as well as messing with the vials all of these variables had to be controlled in order for the experiment to do…
9. Describe how a variable was NOT controlled in one of the two experiments. How might…
Furthermore, when reading over the procedure you can conclude that the controls of this experiment are the layers of turgid spinach layers, the container, the sensors, and the aluminum foil. The variable of this experiment, nonetheless, is the amount of light used throughout the experiment. The reason for this is because you begin with no light and then use the light for the second set of data.…
3. The dependent variable in this experiment is how many stacks of stapled papers each group made.…
In this experiment, the independent variables are the different types of beverages that will be used. The dependant variables (the variables influenced by the different beverages) is the running time (the time that the person will run in one lap), the amount of pushups done in one minute, how many sit-ups is completed by two minutes, and the number of jumping jacks that are done in thirty seconds. I believe that Gatorade will help your athletic performance the most, therefore the other drinks such as water, Arizona Tea, milk, Mott’s Apple Juice, and Coca-Cola is the control group. The controlled variables in the experiment (items that will stay the same) is…
Assignment Question 3: Read the story below and identify the variable, the control group, and the experimental group.…
Mike’s hypothesis is people will drink more soda while watching a Coke commercial in comparison to a Nike commercial. The dependent variable for this experiment was the amount of soda drunk by the test group. The dependent variable was supposed to depend on the commercial shown, the Coke commercial or either the Nike commercial. This is the independent variable because this variable does not depend on another variable. The experimental group was subjects who drank Coke, while watching either the Coke or Nike commercial. No control group was shown in this experiment.…
For the scientist’s experiment the scientist will be experimenting with additives and gel. We will be adding different substances such as table salt, citric acid, and sugar. The scientist’s problem statement is “What kind of substances make gel the strongest?” The independent variable will be the different additives (Table salt, citric acid, and sugar) which will be added using tablespoons. The dependent variable is the strength of the gel which will be measured using a scale of 10. The constant variable is the type of gel used and the amount of substance added to the gel which will be 2 tablespoons.…
4. The experiment observations shall be recorded and data shall be arranged grouped by grade and gender of students participating in the test.…
2. Professor Taylor provides a review session for half the students taking Psychology 101. Later he compares their test scores against those of the other students. What is the dependent variable in this experiment?…
