Does tremolite fluoresce under a blacklight?
Yes, tremolite can fluoresce under a blacklight. It may exhibit a weak to moderate green fluorescence.
Which organelles inside bacteria make green fluorescent protein?
Organelles inside bacteria do not 'make' GFP. GFP can however be expressed in bacteria by adding the coding sequence for GFP to their genome. This can be done by using a plasmid virus containing the GFP gene sequence. When combined with the plasmid, a very small number of bacteria will take up the plasmid's genome into their own. These bacteria can be isolated by using the 'transform or die' mechanism. Bacteria that do not contain the plasmid are preferentially killed by adding an antibody to the agar. The normal bacteria will not be resistant to this, and will die, but the bacteria which have taken up the plasmid into their genome will also contain an antibody resistance gene. This allows them to live in the presence of the antibody. Since GFP was also added to these bacteria's genome, they will fluoresce.
What is the chemical compound in Lysol which causes it to fluoresce under a black light?
The chemical compound in Lysol that causes it to fluoresce under a black light is specific to certain formulations of Lysol and is typically a fluorescent dye such as fluorescein. These dyes absorb UV light and emit visible light, making them appear to glow when exposed to a black light.
Why do some absorbing compounds flouresce and other not?
Absorbing compounds fluoresce because of their molecular structure reduces the probability of non-radiative deactivation processes.
What kingdom is gram positive bacteria?
Kingdom Gram-Positive Bacteria is a kingdom within the domain Bacteria.
Are there lights that show germs on your hands?
You can't see germs with a black light, but might be able to see thick lotion.
Electromagnetic radiation causes certain substanced to fluoresce?
Yes. UV radiation causes phosphor to fluoresce in fluorescent light bulbs.
Does tremolite fluoresce under a blacklight?
Yes, tremolite can fluoresce under a blacklight. It may exhibit a weak to moderate green fluorescence.
What kind of electromagnetic radiation causes certain substances to fluoresce?
Ultraviolet waves of certain wavelengths kill bacteria, tan your skin, and produce the effect known as fluorescence. pg 52 of your textExamples: ultraviolet radiation, visible light.
In what wavelength region does caffeine fluoresce?
When excited by 532 nm green light, caffeine has been seen to fluoresce in the 625 nm wavelength region. This is visible orange light.
What is used to make quantum dots fluoresce for in vivo imaging?
fluorophore

Do maggots glow under a blacklight?
Maggots do not typically glow under a blacklight. While some organic materials can fluoresce due to the presence of certain compounds, maggots themselves do not exhibit this property. However, other insects or materials in their environment might fluoresce, which could create the impression that maggots are glowing.
Why did Crookes cathode ray tube glow green?
The electrons emitted from cathode hit the glass of the tube, causing it to fluoresce.
How does ultraviolet light will help in locating these minerals?
Ultraviolet light can cause certain minerals to fluoresce or emit visible light. By shining ultraviolet light on rocks, minerals that fluoresce can be easily identified and distinguished from other non-fluorescent minerals, aiding in their detection and identification. This property of minerals is harnessed in the field of mineralogy for exploration and research purposes.

Do black lights show germs on your hands?
Black lights, or ultraviolet (UV) lights, can reveal certain substances that fluoresce under UV light, such as some bodily fluids, but they do not directly show germs or bacteria on your hands. Instead, they can illuminate residues from lotions, detergents, or other materials that may be present. To effectively see germs, specialized fluorescent dyes or markers that bind to bacteria must be used. Regular handwashing is the best way to reduce germs, regardless of UV visibility.
