- Q: Are carontenoids and anythocyanin accesory pigments.

- Q: thank you very much for your help!
- This Site Might Help You. RE: what is the role of photosynthetic pigments in plants? thank you very much for your help!
- Q: A.catalyzes chemical reactions.B.absorbs light.C.transports materials.D nverts energy to light.E s energy.
- In biology, a pigment is any colored material of plant or animal cells. Many biological structures, such as skin, eyes, fur and hair contain pigments (such as melanin) in specialized cells called chromatophores. Many conditions affect the levels or nature of pigments in plant, animal, some protista, or fungus cells. For instance, Albinism is a disorder affecting the level of melanin production in animals. Pigment color differs from structural color in that it is the same for all viewing angles, whereas structural color is the result of selective reflection or iridescence, usually because of multilayer structures. For example, butterfly wings typically contain structural color, although many butterflies have cells that contain pigment as well. So pigment reflects color and absorbs light.
- Q: (Explain what happens when a pigment molecule is struck by electromagnetic radiation in the visible light spectrum.)
- pigments are molecules that absorb electromagnetic radiation. For example, the chlorophyll pigment in plants absorbs blue and red light, which is why they reflect green light (since green is the color not absorbed). Another example is melanin, which is the pigment that darkens the skin of people. Melanin absorbs UV to protect the skin. A pigment molecule struck by EM radiation in the visible region may absorb some of the light depending on what pigment it is.
- Q: Please and thank you, it doesn't say so on the website.
- Mac Pigment Ingredients
- Q: What is better, Mac eye pigments or the regular eyeshadow? Also, has anyone tried the mixing medium solution?
- the pigments are more concentrated, but there's more of a color variety with the shadows. on the shadows, if you look under the name it'll tell you the formulation...satin, luster etc...but the ones marked luster and frost are my favorites and they are more vivid and as far as the mixing medium, just dampen (dont wet) your brush and its the same
- Q: Can somebody answer this in AP BIO language please
- A pigment molecule absorbs at specific wavelength(s), meaning that when light of a specific wavelength is incident to the molecule only certain wavelengths are absorbed while others are transmitted. The spectrophotometer emits monochromatic light (light of only one wavelength) which passes through the pigment molecule and a detector determines the amount of light that is either absorbed or transmitted by the sample. This is done at wavelengths from the UV (180-330 nm) to the visible (330-700 nm) and the light that is either transmitted or absorbed is detected by the spectrophotometer and is able to be graphed with absorbance representing the y-axis and wavelength representing the x-axis. The resultant graph will depict the absorption spectrum of that particular pigment molecule. Hope that helps.
- Q: Does anyone know of a way to change the color of your iris' permanently?I've been researching for a while, and have not been able to find anything! I already know about newcoloriris (surgery), but that had loads of side effects. I already know about contacts (ive had them on and off for a while).I don't see how with all the science and technology in the world, there's no way to simply lighten your eye color. We can literally dye our skin, we can tattoo our eyeballs, we can do almost ANYTHING in the world today. So, how has nobody discovered a way to change eye color.?I'm aware that blue/light eyes are a result of low melanin production, But i don't understand how there's no known way to reduce the overproduction of melanin in darker/brown eyed people.It's really frustrating. If anyone knows any websites, doctors, or scientists currently working on a way to do this, please let me know! Or if you know of a new way someone has come up with, please let me know!lt;3 THANKSSSS
- Why in heavens name would you want to do this? The best, and safest way is with colored contact lenses. Don't even entertain the idea of surgery. This is your sight! And yes, though we may change the colour of other parts of our body, consider this - how dangerous and abnormal it is to do so! You probably have very beautiful eyes and don't realize it.
- Q: I was intrested in buying some pigments on ebay but they dont say the name they just say these nubers #68 #69 #93 do u no what pigment name they are u could serch it that might help thank you
- MAC pigments actually have the name listed on the bottom. If the pigments on OKorder do not, you are more than likely looking at fakes.
- Q: is it the ink on regular printers?
- Some printers use only pigmented ink. Others use dye based and then some use a combination of both. Dye based ink is basically water based with a dye added to it. Pigmented ink has a solvent base with dye added. Pigment ink and dye based ink have both advantages and disadvantages. Dye based ink have better colors but pigment are more water and fade resistant. Dye based inks are therefore better for photos. I have a printer that has 4 dye based inks and a black pigment ink. Mine uses the dye based black and colours for pictures and the pigmented black is used for text. So the answer is yes. Pigmented ink is used in some regular printers.
