Gram positive bacterias have a cell wall which will stain in violet color. Gram negative bacterias, howâ¦ever, have an extra layer of cell wall around them which prevents the cell wall from being dyed. These gram negative bacterias will need an additional stain called safranin to make the bacterias redish color.
Grain products like bread, cereal, rice, and pasta are good for you. They are important sources of vitamins and minerals. Breads, cereals, rice, and pasta are also good sources of carbohydrates like starch and fiber. Many people think that starchy foods like breads, rice and pasta are fattening.
Take your pasta out and put it into another pan and put some of the water from where the pasta was boiling from and then put the sauce in. The starch from the water will help the sauce to stick to the pasta and the sauce will get a little thicker. Don't worry about the water, it will reduce as you cook it.
