1.	Where and how do we preserve skieletions of animals,dry specimens
Answer» The entire organism can be preserved by using formalin, alcohol (70-90%) or by freezing. But to preserve the skeleton of animals or dry specimen the following method is used:• Removal of soft tissues: surplus soft tissues from bones was removed by cutting them. The bones were then transferred to 10% NaOH solution and then boiled.• Removal of fatty tissues: by immersing bones in chloroform.• Bleaching: the dried bones were transferred to Hydrogen peroxide for bleaching. • Theses bones are then dried and can be preserved for a long time
