(Help Please It Will Mean So Much!) Procedure: Using potatoes and salt water to take a look at transport across membranes. For the experiment shown, you are going to need to use a cork borer to drive away strips of potatoes and then nicely cut them accordingly, that many should to be the same length. Next you are going to get 6 beakers and every will have three strips of potatoes with a 1 to 5 g of salt and hundred mL water ratio (one beaker getting a 0:1 ratio, becoming the control). Then leave the potatoes for some time as well as measure once the time is actually up. You are going to record the dimensions as well as compute the percentage change for every strip. After, you're able to graph the results of yours to see the higher length of potato strips triggered by osmosis.
In a well-structured paragraph, write an description of a controlled procedure for investigating the new aspect of transport across membranes you've proposed.
