Scientist use fossils to study body structures and compare them.
Scientist use location to study location to see how organisms used their features to cross water or survive in different temperatures.
The natural flow of rivers can be affected by several factors, such as building dams to provide drinking water, pumping of groundwater, climate change, and building of lands that change how natural water runs into surfaces and into rivers. All of these also disrupt the balance of ecosystem in the area.
Hihi!
<span>In general the water should be kept around 100-105 degrees fahrenheit! You should only spend around 10 minutes in the bath at a time, long bathes and showers damage your skin and take out all the moisture in your skin as well!
I hope I helped!
