(1) Prokaryotes have no organized nucleus. Like we said, the DNA is clumped in an area but there is no organized nucleus with a membrane. (2) Prokaryotes do not usually have any organelles. They will probably have ribosomes inside of their cells, but ribosomes are not technically considered organelles. No chloroplasts.
Sateen is a fabric made using a satin weave structure but made with spun yarns instead of filament.The sheen and softer feel of sateen is produced through the satin weave structure. Warp yarns are floated over weft yarns, for example four over and one under.(In a weft-faced satin or sateen, the weft yarns are floated over the warp yarns). Standard plain weaves use a one-over, one-under structure.ateen is a fabric made using a satin weave structure but made with spun yarns instead of filament.
Baleen is a filter-feeder system inside the mouths of baleen whales. The baleen system works when a whale opens its mouth underwater and the whale takes in water. The whale then pushes the water out, and animals such as krill are filtered by the baleen and remain as food source for the whale.Baleen is similar to bristles and is made of keratin, the same substance found in human fingernails and hair. Some whales, such as the bowhead whale, have longer baleen than others.Other whales, such as the gray whale, only use one side of their baleen.he whale then pushes the water out, and animals such as krill are filtered by the baleen and remain as food source for the whale.
