Answer:

Old rivers -have some tributaries

Young rivers -have few tributaries

Mature rivers -have many tributaries

Explanation:

A mature river has many tributaries draining into it, therefore the drainage volume is higher than that of any new river.

While a young river having more gradient than the normal has few tributaries. It flows with a speed that causes degradation of the channel.

While an old river has some tributaries as it is mostly flowing through the flood plains with high level of erosion.

How could you use a microscope to help determine whether a specimen is a living or nonliving thing

lara [203]

Whether living or non living:
When you put a sample of tissue under a microscope, if u can see a cell membrane, and can identify some cell structures like nucleus, mitochondria, vacuoles etc. , it was living, if not, its a non living thing.

However some cells don't have a nucleus( eg. prokaryotic cells), but all cells have a cell membrane or some sort of protective covering to contain the cell's insides. 

To check if your specimen maybe-once living, maybe-still living "something", is living, get a look at it through an electron microscope - thats the best microscope ever- and see if the mitochondria's making any ATP( adenosine triphosphate, source of energy for most organisms), if it does, its living. If not, non living. :)
