half of the number of chromosomes found in the body cells i studi this for science im very good in this stupid^^
He discovered that grasshoppers only have half the number of chromosomes in the body cells.
I believe it was Walter Sutton..He was an American scientist who was the first to provide proof that chromosomes contained the cells units of inheritance. Walter Sutton became the first scientist to provide evidence that chromosomes carried the cells units of inheritance. While he studied grasshopper cells, Sutton observed that chromosomes occurred in distinct pairs, and that during meiosis(form of cell division) the chromosome pairs split, and each chromosome goes to its own cell. In 1903, Sutton discovered that chromosomes contained genes and that their behavior during meiosis was random, concepts that later provided the basis for the Chromosomal Theory of Hereditary.
sex cells.
he observed that grasshopper body cells and sex cells have the same number of chromosomes
Walter Sutton was a U.S. geneticist who provided the first evidence that chromosomes carry the units of inheritance and occurs in distinct pairs.
body cells of a grasshopper has 24 chromosomes and 12 chromosomes in the sex cells so as many body cell chromosomes you have you will have half that number of chromosomes in your sex cells.
Walter Stanborough Sutton was an American geneticist. He discovered that an organism has half the number of chromosomes in sex cells that it has in its body cells. A geneticist is a branch in science about the difference in living organisms. Sutton was born in Utica, New York on April 5, 1877. At age ten, Sutton moved with his family to Russell County, Kansas, where he attended public schools. He studied engineering at the University of Kansas, beginning in 1896. After his younger brother's death from typhoid in 1897, he made an essential change in the course of his education that would eventually lead him to the study of medicine and to his discoveries in genetics. He received Bachelor and Master degrees from the University of Kansas. Sutton then attended Columbia University and obtained the highest university degree, in medicine in 1907. He died on November 10, 1916. Sutton's name will always be associated with that of Theodor Boveri. They are jointly credited with having proposed, independently in 1902, the chromosome theory of inheritance.

Penicillin..used for bacteria infections...
Yes.
I don't know man, I'm looking for the same response myself.
