They are independent
they have branches which are also independent
each branches can work on there own
but the combination of the branches makes work easier
while the combination of the branch's parent,makes it much more easier.

(clue:We use them)

does that means no one can get answer to this?
it very simple ,they are useable to us, infact we carry them all around.
pls think and find an answer to it

The answer is parent coz when d parent gave birth they re having branches

funsho234:

The answer is parent because when d parent gave birth they re having branches

Oh no sorry that is not the answer,please keep trying

OK maybe i should drop more clues:
we all use and have them on our body
they perform essential rules and functions

I knew i would get it.

Its the HAND. rigth?

hmmmmmmmmmmmmmmmmm,that is gud of u with the help of my clues,but u did not explain it ooooo

its the hand because:

They are independent the hand to some extent is independent as it can help its self most of the time.
They have branches which are also independent The branches are the fingers and each finger can work alone.
Each branch can work on their own As i have said above
But the combination of the branch makes work easier Its easier to work with five fingers than one. isn't it? (e.g, typing)
Combination of branch's parent makes it easier Yeah the arm makes it easier to work with your hands.

(clue: we use them) yes we use our hands of course.
