Forgetting to flame the loop between streaks in a streak plate can result in mixed or contaminated cultures.
Dragging the inoculation loop through a previous quadrant when streaking to a new quadrant is important to obtain isolated colonies and pure cultures.
The streak plate technique is a method used in microbiology to isolate and obtain pure cultures of microorganisms. It involves streaking a sample containing a mixture of microorganisms onto an agar plate in a pattern that allows for the separation and growth of individual colonies.
When performing a streak plate, it is important to flame the loop between streaks. This step sterilizes the loop, preventing cross-contamination between different quadrants of the plate. By forgetting to flame the loop, there is a higher chance of carrying over microorganisms from one quadrant to another, resulting in mixed or contaminated cultures.
Dragging the inoculation loop through a previous quadrant when streaking to a new quadrant is important for diluting the number of microorganisms being transferred. This technique ensures that each quadrant receives a decreasing number of cells, allowing for the growth of isolated colonies. It helps to obtain pure cultures for further study and identification.

Answer: The correct answer is- C) Protists.
Dysentery is an inflammatory disease of the intestine, especially of the colon region ( a part of large intestine) that causes extensive pain in the abdomen and severe diarrhea. Apart from this, it also includes symptoms such as fever and an incomplete defecation feeling.
Amoebic dysentery is also known as amoebiasis and caused by Entamoeba histolytica, which is a protist.
