Answer:
Rise:
Taxing the Trade Route,
Limiting Gold Mining Activities,
Gold Deposits,
Trade of Gold and Kola Nuts
Fall: Invasion of Ghana, Losing Control
Explanation:
By taxing the route, they profited. Limiting mining activities decreased production and increased the value- things are always more valuable when there are not many of them. Trade of gold and kola nuts made profit, gold deposits kept gold plentiful, and invasion and losing control, of course, will contribute to anybody's fall.
in the course of fish evolution, two of the gill slits slowly advanced into the jaws.
The evolution of fish started about 530 million years in the past at some point during the Cambrian explosion. It become during this time that the early chordates advanced the cranium and the vertebral column, main to the first craniates and vertebrates. the first fish lineages belong to the Agnatha or jawless fish.
The earliest fish, corresponding to living hagfish, developed about 550 million years in the past. Diversifications that in the end advanced in fish include an entire vertebral column, jaws, and an endoskeleton manufactured from bones in preference to cartilage. Fish live in the course of the sea and in freshwater lakes and streams.
New studies have uncovered the genetic foundation of gill covers in fish, which came about over 430 million years ago. It sheds light on one of the most essential evolutionary traits for fish, in addition to over vertebrates.
In jawless fishes, a sequence of gills opened behind the mouth, and those gills became supported by way of cartilaginous elements. the primary set of these elements surrounded the mouth to shape the jaw.

Answer:China did the trading
Besides silk, the Chinese also exported (sold) teas, salt, sugar, porcelain, and spices. Most of what was traded was expensive luxury goods. This was because it was a long trip and merchants didn't have a lot of room for goods. They imported, or bought, goods like cotton, ivory, wool, gold, and silver.
Because silk was the major trade product which traveled on this road, it was named the Silk Road in 1877 by Ferdinand von Richthofen – a well-known German geographer. This ancient route not only circulated goods, but also exchanged the splendid cultures of China, India, Persia, Arabia, Greek and Rome.
