Answer 1

1.Hard bones are impregnated with calcium phosphate and stretchy collagen which makes them hard and unable to fold or twist whereas cartilage is made up of soft collagen and cells called chrondocytes which is why it can be twisted and folded.

2.Dialysis removes fluid and waste

The main purpose of dialysis is to replace impaired renal function. When your kidneys are damaged, they are no longer able to remove wastes and excess fluid from your bloodstream efficiently. Waste such as nitrogen and creatinine build up in the bloodstream.

Answer 2

Answer:

The bone is made mostly of collagen. Collagen is a protein that provides a soft framework, and calcium phosphate is a mineral that adds strength and hardens the framework. This combination of collagen and calcium makes the bones strong and flexible enough to withstand stress. Thus the bone cannot be folded.
