Because the organism is distributed across the world, and isn't seen anymore, scientists can conclude tat they must have evolved. They can compare one species to the fossils they may have found, and determine that they were related. Then by looking at the species on another part of the world compare the same fossils to other animals and determine that they are similar, sharing a common ancestor.

I will choose : Malaria.
Malaria is an infectious disease caused by a parasite of the genus Plasmodium (the most predominant is the falciparum species), spread by the bite of certain species of anopheles mosquitoes. The malaria parasite is mainly transmitted, at night, during the bite by a female mosquito of the genus Anopheles, itself contaminated after stinging an individual with malaria. The parasite infects the victim's liver cells and then circulates in the blood, colonizing the red blood cells and destroying them.
The symptoms are: generalized fatigue, loss of appetite, dizziness, headache, digestive disorders (gastric embarrassment), nausea, vomiting, abdominal pain, diarrhea and diffuse myalgia.
The answer to your question is that the color and specific gravity at the three stages, Tracy might conclude that Max is extremely well hydrated before exercise as the urine is pale and has a low specific gravity,dehydrated after immediately exercise as it is a dark pigment with a high specific gravity and adequately hydrated six hours after exercise as it is a normal pigment and normal specific <span>gravity.</span>
