They used Neurospora Crassa (a bread mold). It could grow in a simple medium which helped aid in their research.
Anaerobic bacteria such as certain strains of Escherichia coli and Clostridium are commonly used for anaerobic respiration in laboratory experiments.
Gregor Mendel conducted his experiments on pea plants (Pisum sativum) to study heredity. He chose pea plants because they were easily grown, had observable traits that were easy to control, and exhibited clear patterns of inheritance.
To induce different results.
Type of living tissue or organism that has had its DNA changed in or from the use of reproduction, scientific experiments, or natural order, making this specific life structure, "genetically altered." Deals with the change of cells, or other tangible micro-unit in the living object at hand.
yes
Mr Bumble had the post as "Beadle" to keep order at Oliver Twist's school in the Dickens novel.
No I doubt whether it is rare, as my school has about 200 copies of The Beadle (we use it for our literature studies). I'm not shure about its availibility though.
Rhizopus: Fungi of the species Rhizopus stolonifer are one of the most common and fastest growing fungi in the phylum Zygomycota. The black bread mold, as it is more commonly known, also causes rotting of fruits and some infections of humans. This species of fungus dissolves the food it grows inside of, using extracellular enzymes, then it absorbs the nutrients for use by the mold. Neurospora: The red bread mold Neurospora crassa is one of the most important fungal species used by biologists, second only to baker's yeast. In 1958 George Wells Beadle and Edward Lawrie Tatum used red bread mold in their experiments, which led to the "one-gene-one-enzyme" hypothesis and the awarding of the Nobel Prize in Physiology or Medicine to Beadle and Tatum. Since Beadle and Tatum, scientists have used red bread mold in their experiments concerning epigenetics, gene silencing, cell fusion, and circadian rhythms. Penicillium: Fungi of the genus Penicillium, when growing on bread, appear as blue-green to gray fuzzy patches of colonies with white borders. Penicillium fungi grow well at low temperatures, so if you find mold growing on bread kept in the refrigerator, it is probably Penicillium. Apart from ruining your bread, Penicillium was the first mold found to produce antibiotics, and it is used by physicians to kill specific types of bacteria in the body. The mold growing on your bread, however, is probably a different species of Penicillium and should not be eaten as many people are allergic to it and can suffer severe reactions.
Make stuff for experiments, do experiments and analyse the results of experiments.

we are all scientists. we all use experiments
Scientist design experiments to test something.
they use it to keep track of their experiments
use it for doing experiments
Scientific equipment.
they use controlled experiments to help them find out if it works or not.
Scientists use controlled experiments because the results are consistent and can be replicated. The control of an experiment is the value that you are controlling the dependent variable to.
