You conduct an experiment to determine the concentration of ions in an unknown solution. you place 300ml inside a dialysis bag and place the bag into a beaker of water with an ion concentration of 100 ppm (parts per million). when you check the experiment an hour later, the bag is deflated and has lost much of its water. what can you conclude?

Choose one animal (cheetas) and research on the internet what has contributed to this animal becoming "endangered" or "threatened." what animal you have chosen? how long has the animal been endangered or threatened? what has contributed to this animal’s endangered or threatened status? why is it important to save this animal from extinction? after researching and gathering facts, write a 350-word letter from the point of view of an animal rights' activist. be sure to include at least five facts that you learned from your research.
