Model 1 Model 2 Sometimes variables that were significant in a model may become insignificant in subsequent models. Refer to model 1 and model 2 to see whether we have any independent variables that are significant in model 1 and insignificant in model 2, and which ones are they (if any). If there are variables that are significant in model 1 and then turn insignificant in model 2, what may be the reason?

A tube with a membrane covering the bottom is placed in a beaker. The membrane allows water to flow through but not salt or glucose. If the tube contains an aqueous solution with4% salt and 20% glucose and the beaker contains an aqueous solution with 12% salt and 6% glucose, what would happen to the level of the water in the tube?
