What is the difference between knuckle-walkers and palm-walkers?

What is the difference between knuckle-walkers and palm-walkers?

Primate mammals – apes and monkeys – are either knuckle-walkers or palm-walkers. 

All apes, such as the Chimpanzee, Gorilla, and Orangutan, have no tail.

All monkeys have a tail. 

Apes and monkeys use their front arms to help them walk on all fours (all four appendages). They place their two long front arms and hands on the ground, with either their knuckle on the ground or the palm of the hand on the ground. 

The knuckles are the lumps on the back of the hand at the base of the fingers.

The palms are the soft, cushioned part of the front of the hand. 

So, which ones are knuckle-walkers and which ones are palm-walkers?

What is the difference between freshwater Flowing Water and Standing Water?

What is the difference between freshwater Flowing Water and Standing Water?

Flowing water occurs on land in freshwater streams and rivers. Flowing water usually begins to flow due to snowmelt or lakes that overflow. The water usually flows to the sea.

Flowing water can be fast-moving, slow-moving, or stagnant (not moving – it is motionless). Scientists usally regard motionless water to be stagnant if it has not moved in four consecutive days.
