Ciliate conjugation is a sexual phenomenon that results in genetic recombination and nuclear reorganization within the cell. In most ciliate groups, however, the cells separate after conjugation, and both form new macronuclei from their micronuclei.
Before the bun, hamburgers are said to have been served between two pieces of bread. In fact, a ground beef patty was known as Hamburger steak (first mentioned in an American cookbook in 1891); when this was put between bread or in a bun it was called a Hamburger sandwich.
The hamburger was 2,014 pounds, the largest burger in world history. It was 10 feet wide, topped with 60 pounds of bacon, 50 pounds of lettuce, 50 pounds of onions and 40 pounds of cheese. It took a construction crane to flip the patty over. The burger was created by the Black Bear Casino Resort in Carlton, Minnesota.
