Prompt: It is common knowledge that stayinghydrated is beneficial and that electrolytes replenish the bodyafter exercise. But did you know that it too much water or watercontaining the wrong substances can be harmful? Apply what you havelearned about osmosis and diffusion in Hands On Lab: Cellsand Membrane Transport to consider the followingscenario:

You are stranded on a desert island. A boat will not be by thisarea again for 7 days so you need to make smart choices to survive.This sunny island, Puerto Golgi, with an average daily temperatureof 95 degrees Fahrenheit, receives only a few inches of rain peryear, so there is very little fresh water available for you todrink.

You have 3 options to choose from and you may onlychoose one:

1. Drinking all the freshwater from a midweek rainstorm in 1hour before it evaporates (4 Liters).

2. Drink a small amount of saltwater each of the 7 days

3. Crack open the available coconuts to drink 2L of coconutwater each day

Which option will you choose to survive until the boat arrivesat the end of day 7 to find you and take you back to the mainland?Each option has beneficial and harmful aspects; there is noperfect choice available.

Through this 2 part discussion with your classmates, you willstate your choice, explain how your choice would affect the bloodand cells of the body using appropriate and sufficient evidence,and then respond to your classmates posts to convince them why thatchoice is the optimal one for survival. In other words, youneed to know why your choice is the most optimal for the human bodyand why the other choices would not be.

Remember, no answer is one hundred percent correct so you arenot saying that others are wrong, but instead why your choice ismore optimal based on evidence. We all want to survive and get eachother safely to the mainland.

Part 1: Initial Post (Worth up to 50points)

• Length: 250-500 words

• You will need to use at least 3 reputable scientific referencesto support your post (not including your textbook). Reputablesources= peer reviewed scientific journal articles, accreditedwebsites, or books. Google, Wikipedia, etc. are not acceptablesources.
