- 29. Multiple ChoiceIf you are stranded at sea (oh no!) why is it safer to drink urine than sea water?One cup of sea water has enough sodium to poison you.Sea water is hypertonic to your cells and will only further dehydrate you.Sea water is too isotonic to your cells and you will absorb too much water.The salt will cause high blood pressure and you will die from a stroke.
