A condition in which bones become weak and brittle.
Answer:
The ancient Egyptians were far from primitive. They were some of the best inventors of their time, creating technology that surpassed that of other civilizations during this time period.
Explanation:
- Around 3000 BC, Egyptians discovered how they could make bronze, which was far more durable than other metals during that time. This innovation started the Bronze age.
- Ancient Egyptians were among the first groups of people to write and to keep records.
- The ancient Egyptians turned the Cyperus papyrus plant into sheets which could be rolled into scrolls. They basically created the first paper.
- To write on the newly invented paper, they created ink made for writing.
- The Egyptians devised a highly accurate solar calendar by recording the yearly reappearance of the star Sirius (the Dog Star) in the eastern sky.
- The Egyptians used obelisks as sundials, by observing how shadows cast by the obelisk moved around them during the course of the day. This acted as a clock.
