D. Slavery helped slave families stay together on plantations.
E. Slaves were required to grow crops on plantations.
Answer:
E. Slaves were required to grow crops on plantations.
Explanation:
Pro-slavery Americans claimed that slaves were essential to the supply of agricultural products in the country. This is because it was the slaves who did the whole process of sowing, maintaining, harvesting, processing and distributing agricultural products from southern crops. These people who defended slavery, claimed that freeing the slaves would dissolve all this labor and block the productivity of the national agricultural sector.

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.
