Answer:
Ribosomes are found 'free' in the cytoplasm or bound to the endoplasmic reticulum (ER) to form rough ER. In a mammalian cell there can be as many as 10 million ribosomes. Several ribosomes can be attached to the same mRNA strand, this structure is called a polysome.

Hope this helps :D
They provide an important habitat!
Yes it is absolutely true that each lung is fed oxygen by a separate bronchus. There are actually two lungs and two bronchi. Each of the two lungs are safeguarded by the two ribcages as
they are placed within the rib cages. The lungs actually consists of elastic
sacs that contract and expand for taking in and releasing air. This way oxygen
is passed into the blood and carbon dioxide is taken out from the blood and
passed out. This is also the main function of the lungs.
The bond between CH2 and P of phosphate through O is called phosphoester bond. Only one such bond is present in both AMP and ADP.Link of phosphate groups through O by elimination of water molecule is called phosphoanhydride bond.In AMP, only single phosphate group present so no phosphoanhydride bond is present. But inADP, two phosphate groups are linked by one phospoanhydride bond.AMP 1 0ADP 1 1
A Ribosome is not a membrane bound organelles
