The dye stains the bacteria, thus giving them color. Before they were stained they were colorless. It's very hard to see the details of something clear but when colored it's easier.
No, germs cannot be seen with a UV light. UV light can be used to disinfect surfaces by killing germs, but it does not make germs visible to the human eye. Germs are microscopic organisms that are not visible without the use of a microscope.
When crystals of dye are placed in water, they will dissolve if the dye is soluble. The dye molecules will disperse in the water, creating a colored solution. If the dye is insoluble, the crystals will remain visible in the water.
Germs make more germs through a process called reproduction. This can happen through methods like binary fission, where a germ splits into two identical daughter cells, or through sexual reproduction in some species of germs. The exact mechanism varies depending on the type of germ.
On the second day, the plant will continue to absorb the dye through its vascular system, resulting in more visible coloration throughout its tissues. The intensity of the color may deepen as more dye is absorbed.
The number of germs needed to make you sick can vary depending on the type of germ, your immune system, and other factors. Typically, it only takes a small amount of certain harmful germs to cause an infection or illness. Practicing good hygiene, such as washing your hands regularly, can help reduce your risk of getting sick from germs.
No, germs cannot be seen with a UV light. UV light can be used to disinfect surfaces by killing germs, but it does not make germs visible to the human eye. Germs are microscopic organisms that are not visible without the use of a microscope.
In gel electrophoresis, DNA is treated with a dye that binds to the DNA molecules, making them visible as bands under ultraviolet light.
When crystals of dye are placed in water, they will dissolve if the dye is soluble. The dye molecules will disperse in the water, creating a colored solution. If the dye is insoluble, the crystals will remain visible in the water.
The red dye is added to make it easier to read the temperature scale on the thermometer. The dye provides a contrast against the clear liquid, making it more visible and accurate to read the temperature markings.
Orange dye is made by combining a yellow dye and a red dye.
no germs do not always make us sick some are good!
You need orange dye and blue dye. Aggie in Draynor Village can make red, yellow and blue dye. Combine the red and yellow to make orange dye.
Unhygienic living conditions make germs multiply. They like moist places with little hygiene. Huge multiplication of germs around you can be bad for your health.

A scientist might use colored dye to enhance the contrast and make specific structures or features more visible. Dye can help highlight certain parts of a specimen, making it easier to observe and study under a compound light microscope.
Light helps in revealing the presence of germs by making them visible through a process called fluorescence. When certain substances in the germs absorb light, they emit a different colored light that can be detected with special equipment. This allows scientists to identify and study the germs more easily.
yes and no. some germs could be bad to your health, for example, germs are the reason you get sick. but that is only a type of germ. there are germs every where! and not ALL of them are bad, some are bad, but not all. therefore, u should be careful with wat you tuch, but dont worry too much because not all germs are bad
