What is the independent variable in the dialysis tubing experiment?
What is the independent variable in the dialysis tubing experiment?
For these questions, the independent variable is the sucrose concentration, and the dependent variable is the height of water rise. Constants include use of the same type of dialysis tubing, the same placement of the tubing in the water (depth of water), and the same sucrose solution temperature.
What is the dependent variable in the membrane diffusion experiment?
Independent variable: Surface area of the semi-permeable membrane Dependent variable- The time in which the cell takes to reach equilibrium by passing through the membrane Table 1: The controlled variables of the experiment.
What is the dependent variable in the osmosis lab?
Independent Variable – The concentration of sugar solution. Dependent Variable – The mass of plant tissue at the end.
What does the dialysis tubing represent in your experiment?
Dialysis tubings are often used in experiments that are demonstrating the process of osmosis. Osmosis is a special kind of diffusion where water moves across a semi-permeable membrane and travels from a region of high water concentration to a region of low water concentration.
What is the meaning of independent and dependent variables?
The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.
What is diffusion quizlet?
What is diffusion? Diffusion is the spreading of the particles of a gas, or of any substance in solution, resulting in a net movement from a region where they are of a higher concentration to a region with a lower concentration.
Which variables affect the rate of diffusion select all that apply?
Several factors affect the rate of diffusion of a solute including the mass of the solute, the temperature of the environment, the solvent density, and the distance traveled.
What controlled variable?
A control variable is an element that is not changed throughout an experiment, because its unchanging state allows the relationship between the other variables being tested to be better understood.
What is the independent variable in an experiment?
Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn’t changed by the other variables you are trying to measure. For example, someone’s age might be an independent variable.
What specific component of the kidney does the dialysis tubing represent?
ureters
The specific part that the dialysis tubing represents are the ureters- which are two narrow tubes in the body. The function of the ureters is to help…
What is dialysis tubing used for and why is it effective?
Dialysis tubing is a type of tubing used in medicine to remove toxins from a patient’s bloodstream. It is effective for this purpose because it is a semipermeable membrane, allowing some particles to pass through while blocking others, and so can be used as a filter.
What are the 3 types of variables?
These changing quantities are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled.
What was the equipment used in dialysis tubing experiment?
Get Your Custom Essay on Dialysis Tubing Experiment Lab Report The equipment used was: 5 dialysis tubing, a scale, beakers, water, egg white, sucrose, glucose, Nasal, and 5 cups. We put the five dialysis tubing filled with one of the five substance into a cup filled with one of the substance: water, egg white, Nasal, glucose, or sucrose.
What is the dependent variable in the dialysis experiment?
DEPENDENT VARIABLE: The dependent variable was the mass of the dialysis tubing after sitting in the beakers containing the mystery solutions. METHOD FOR MEASURING CHANGE IN DEPENDENT VARIABLE: A method for measuring the change in dependent variable would be measuring the mass of the dialysis tubing before…
What happens when dialysis tubing is submerged in different substance?
If the dialysis tubing is submerged in different substance than what is in the tubing then some of the alkalis tubing will lose mass and some will gain mass. To begin this experiment we filled 5 dialysis tubing with one of the five substances: water, egg white, Nasal, glucose, or sucrose.
Is dialysis tubing permeable to glucose starch and iodine?
The dialysis tubing was not permeable to all the three solutions-glucose, starch and Iodine (Potassium Iodide). Rather, the tubing was permeable to glucose and iodine but not starch. This could be known from the color change in the solutions in the beaker and the bag.
