yes
How do scientists study how bacteria are affected by antibiotics?
Laboratory scientists culture a bacterium (one single bacteria) so the bacteria grows to a colony. Scientists create many specimens of colonies for each bacteria. Then they can expose each colony to a different antibiotic medication or new antibiotic to see how the bacteria react to it. They look for sensitivity--meaning, any reaction in the growth of the bacterial colony. The growth may have no change (no sensitivity), slow down, or stop. But even better, ingredients in antibiotics need to disrupt the way bacteria use nutrients, so scientists look to see if the bacteria die when exposed to that specific antibiotic.Different groups or families of antibiotics work best on certain bacteria. At the same time, certain bacteria favor conditions only in certain areas of the body. So the bacteria for a skin infection is different from the bacteria that infects the urinary tract, for example.
What fungus produces a substance that can kill bacteria?
One fungus that produces an antibiotic and will kill some bacteria is Penicillium.
Why do you think Griffith called the mystery material the transforming principle?
Griffith called the mystery material the "transforming principle" because it was responsible for transforming non-virulent bacteria into virulent ones. This process demonstrated the ability of the material to transfer genetic information and change the phenotype of the bacteria.
Scientists have identified more than a kinds of unicellular organisms?
Scientists have identified more than a million kinds of unicellular organisms, ranging from bacteria to protists. These organisms play important roles in various ecosystems, from nutrient cycling to disease transmission. Their abundance and diversity make them a key focus of research in microbiology and ecology.
The transforming factor that alters pneumonia?
The "transforming factor" that alters pneumonia bacteria was found to be DNA by the scientist Fredrick Griffiths.
How did Avery help our understanding of genetics?
He showed that DNA is a Transforming factor.

How are Shigella bacteria identified?
Shigella are identified by a combination of their appearance under the microscope and various chemical tests.
Scientists use bacteria to produce?
Insulin-producing bacteria were commercialized in 1982.
Why did scientists place bacteria in their kingdom the monera?
Scientists placed bacteria in their own kingdom, the Monera, because bacteria lack the nuclei, mitochondria, and chloroplasts found in other forms of life
