How many dextrose and how many water molecules are needed in the extracellular fluid so the fluid will be isotonic with the cell? [Note: the extracellular fluid must remain at 250 total molecules, so you will have to adjust the number of water molecules in the fluid accordingly.] Show your calculations.

You are performing an experiment to determine if a solution is hypertonic, hypotonic or isotonic in relation to cells placed into the solution. Using your background knowledge and research on osmosis, answer the questions below. Describe what you would expect to happen to the cells if they are placed in the following:(1 pt for each description) Hypertonic solution Isotonic solution Hypotonic solution Calculate the average weight for each measurement below. Be sure to show your work. (2 pts) Then, use the data below to determine if the solution the cells were placed into was hypotonic, hypertonic or isotonic. How do you know that this is the case?(2 pts) Time (minutes) Weight 1 (g) Weight 2 (g) Weight 3 (g) Average (g) 0 4.2 4.34 4.3 5 3.7 3.68 3.72 10 3.3 3.26 3.32

When observing your cells under the microscope after the experiment, you noticed that they appeared to adapt well despite the rapid osmotic changes. Based on this, do you predict that the cells placed in the solution are animal cells or plant cells? (1 pt) Why? What adaptations allow these cells to adapt to different osmotic environments? (1 pt) (1 pt for appropriate reference use)
