- Q: list 5 mineral pigments and 5 animals pigments and how its produced
- Mineral Pigments: Lazurite (Lapis Lazuli), Vivianite (Blue Ochre), Riebeckite, Glauconite, Malachite, Jarosite, Limonite, Hematite, Goethite, Celadonite and Shungite Animal Pigments: Tyrian Purple, made from the mucus of a Murex snail Carmine, made from an insect in central and south America, called Cochinilla Natural indigo, made from plants of the genera Indigofera Rose madder, a pigment derived from the plant Rubia tinctorum Gamboge, I think is a dark type of mustard (seeds) Alizarin occurs in the root of the common madder (Rubia tinctorum) and in various parts of Indian madder (Rubia cordifolia). And regarding how they are produced, well each one has it?s own methods. You may want to search each of those names and you can find information for each one. Hope this helps, Bella
- Q: explain an absorption spectrum of different pigments and the action spectrum ofphotosynthesis.
- A pigment is any substance that absorbs light. The color of the pigment comes from the wavelengths of light reflected (in other words, those not absorbed). Chlorophyll, the green pigment common to all photosynthetic cells, absorbs all wavelengths of visible light except green, which it reflects to be detected by our eyes. Black pigments absorb all of the wavelengths that strike them. White pigments/lighter colors reflect all or almost all of the energy striking them. Pigments have their own characteristic absorption spectra. The action spectrum of photosynthesis is the relative effectiveness of different wavelengths of light at generating electrons. If a pigment absorbs light energy, one of three things will occur. Energy is dissipated as heat. The energy may be emitted immediately as a longer wavelength, a phenomenon known as fluorescence. Energy may trigger a chemical reaction, as in photosynthesis. Chlorophyll only triggers a chemical reaction when it is associated with proteins embedded in a membrane (as in a chloroplast) www.emc.maricopa.edu/faculty/fara...
- Q: I am about to purchase a bunch of MAC pigments and I have noticed that they all look glittery, is this just the kind that i am looking at? I know they are versatile, so that is why i want to buy them. And it seems as though they will last longert than eyeshadow...
- Of course they can ! I love mac pigments. Yes, fallout is involved..but what i do is i use my mixing medium with them so that they go on wet and no fallout. If you don't have mixing medium you can mix them with eyedrops. What i do is i put a drop in the lid and pick up some pigment and mix it till i get the perfect consistancy. You can also learn how to press them, so that they can become pressed eyeshadows instead of loose. But if you just want to use them loose, make sure you get a good flat shader brush...make sure you pat the pigment on your lids insted of in a swiping motion, this also prevents less fall out. Get some loose transparent powder as well set that under your eyes, and swipe it off when done..this makes the fallout swipe away without smearing on your face.. Hope that helps ! If you want you can do all of this, but you don't have to...just random tips to prevent that annoying fallout
- Q: I know the difference between the two, but which do you prefer? Which has a better color payoff? And, which do you own more of?
- MAC pigments. The color is just so rich and it lasts really long.
- Q: Does albinism cause lack of ALL pigment, or just black pigment? Does this very on the species?
- Mammals and birds only have melanocytes (these produce varying amounts of brown or black pigment), so that's the only pigment that needs to be affected for them to display albinism. But other types of animals have multiple types of chromatophores. An albino snake, for example, would also need to have the cells that produce reds, yellows, and blues deactivated to appear white/colorless. For these animals to appear as albinos, all pigments would have to be affected.
- Q: I am trying to decide what kind of eyeshadow I should but I want something really pigmented and nice.
- Highly Pigmented Eyeshadow
- Q: whats it for? lol
- itz for ur beautifing ur skin.
- Q: Pleaseeeeee answer A.S.A.P Pleaseeee! Are pigments haram?
- Pigments are extracted from plants as well as animals . For more kindly click on the link below = en.wikipedia.org/wiki/Biological_... Most of the pigments that we use are either from plants ,from minerals or synthetic in origin . Most of the edible pigments are synthetic or from plants so they are not haram . It is now compulsory to indicate any animal material used in any edible product including tooth pastes by a deep red square on the label . If it is 100% plant product then green squre is shown on the label . So you can judge if it is Haram or not by yourself.
- Q: Many of the microorganisms found on environmental surfaces are pigmented. Of what possible advantage is the pigment?
- Pigments have many advantages for the cell. They can absorb light to be used in photosynthesis. Specific pigments absorb light in a specific range - so the more pigments the more light can be absorbed and used for photosynthesis. Pigments also protect the cells from damage by UV radiation. More recently it has been suggested that some pigments inhibit the growth of some microorganisms.
- Q: i got some pigments off of ebay and i received two of them but they have a funny smell to them? are they supose to?
- Are you sure they are real mac pigments. Look on the bottom to see if they have names. If not, if they just have a number and not a name, then they are fake and thats probably the cause of the smell. If so, then I don't know. Mine never do. Hope this helps and good luck!
