Independent and dependent controlled variable digestion carbohydrate
Explore the fundamentals of the scientific method, independent variable, dependent variable, control variables, the relationship between variables, and experimental design students arrange variables on their “shuffleboard” and, based on their arrangement, formulate a question to investigate the relationship between the independent and. The dependent variable is the amount of food that is digested by the cat the constants (control variables) are the amount of cat food that the cat is fed, the ph level of hydrochloric acid, the amount of acid used, and the amount of meat tenderizer used. An experiment usually has three kinds of variables: independent, dependent, and controlled the independent variable is the one that is changed by the scientist to insure a fair test , a good experiment has only one independent variable. A spatially continuous mathematical model of transport processes, anaerobic digestion and microbial complexity as would be expected in the human colon is presented the model is a system of first-order partial differential equations with context determined number of dependent variables, and stiff. However, some of the “available carbohydrate” (ie, “available” for small intestinal absorption: total carbohydrate minus dietary fiber) in many foods may also escape digestion in the small intestine in appreciable amounts and become available for fermentation by colonic microflora.
There are two types of experiments when it comes to any experiment the variable varies depending on which is being tested in the experiment and which one is controlled in the experiment. The variable varies depending on which is being tested in the experiment and which one is controlled in the experiment test out how well you understood the two in class by taking the quiz below all the best. An independent variable is a variable whose variation does not depend on that of another it is the variable that is controlled or changed in an experiment in order to test the effect on the dependent variable. Randomized controlled trials are one of the most efficient ways of reducing the influence of reducing the influence of external variables this article is a part of the guide.
Our independent variables will be benidict's reagent and biuret reagent our dependent variable will be starch and hcl the negative control of the experiment will be the mixture of starch, h20, and benedicts reagent. In any experimental design, a researcher will be manipulating one variable, the independent variable, and studying how that affects the dependent variables a failure to isolate the controlled variables will compromise the internal validity. There are two types of variables that exist in most experiments: independent and dependent variables • independent variables are factors that can be controlled or manipulated by the researcher • dependent variables are factors that are measurable and change because of the independent variable.
A dependent variable in biology is an element that is being tested it relies on the independent variable, or that aspect of the experiment that the scientist has control over and changes to observe the results on the dependent variable. Therefore, the dependent variable was running performance, and the independent variable was formula, which consisted of two related groups: carbohydrate-protein and carbohydrate-only to carry out the experiment, the researcher recruited 20 middle distance runners. Inquiry labs in biology photos are of mrs king's amazing students in action carbohydrates metabolized by yeast titration diffusion/osmosis drosophila melanogaster seeds and plant growth lima beans bottle biology comparing independent and dependent variables chromatography plant pigment coming soon beet tip transpiration. A postive control is the variable for which you are testing iodine interacts with these coiled molecules and becomes bluish black iodine doesnt react with carbohydrates that are not coiled and remains yellowish brown therefore avoiding the reaction to occur dependent variable is temp and independent is the time of the starch. Topic 2: control of the digestive system graphics are used with permission of: lipid rich meal → longer digestion time carbohydrate rich meal → shorter digestion time dependent insulinotropic peptide (gip) and motilin.

Pp lab report digestion essay pp lab report digestion essay 1569 words mar 23rd, 2015 7 pages laboratory report dependent variable number of radiopaque markers in gi tract 2 independent variable amount and type of fiber in meal controlled variables calories in meal, nutrients in meal effect of dietary fiber on bile acid. This activity will allow students to measure the rate at which the photosynthesis process occurs students will work in small groups to design an experiment with one independent variable and test this variable on spinach leaf disks. Men consumed each diet for 50 days whereas women consumed the diets for approximately 30 days in order to control for possible effects of menstrual phase on some of the dependent variables measured in this study [23, 24] all testing for women was performed between days 2–4 of the follicular phase as self-reported by the women.
Identify the dependent and independent variables (hint: there are two independent variables you investigated, but only one dependent variable) 2 describe the relationship between substrate and the product. Answer to what is the independent, dependent, and control variable of the benedict's test, lugol's test and buret's test the pict skip navigation show transcribed image text carbohydrate identification 2 test tubes were labeled as negative and positive 2ml of hzowere need t for the negative test tube and 2 ml of coh12oefor the positive. Human digestive system paper, order, or assignment requirements discuss the independent and dependent variables for your experiment b explain the controlled variables for your experiment 2 a hypothesis in which you do the following: a predict the relationship that exists between the independent and dependent variables.
Dependent variables are flat c will be your control variable your independent variable is the age of compost and your dependent variable is the growth (color, size, weight) of the tomato plants so basically your independent variable causes change in the dependent variable. Now determine the dependent, independent, and controlled variables for each experiment in this laboratory activity by clicking on the appropriate answers check your answers until you have chosen all variables correctly. Dependent variable number of radiopaque markers in gi tract 2 independent variable amount and type of fiber in meal 3 controlled variables calories in meal, nutrients.
