Q:what is pigment dispersion syndrome?

Pigment dispersion syndrome (PDS) is an affliction of the eye that, if left untreated, can lead a form of glaucoma known as pigmentary glaucoma. It takes place when pigment cells slough off from the back of the iris and float around in the aqueous humor. This is not what causes problems; however, if the pigment flakes clog the trabecular meshwork, preventing the liquids in the eye from draining, pressure can build up inside the eye. This pressure can cause permanent damage to the optic nerve. This condition is rare, but occurs most often in Caucasians, particularly men, and the age of onset is relatively low: mid 20s to 40s. Most sufferers are nearsighted. There is no cure as of yet, but PDS can be managed with eye drops or treated with simple surgeries. If caught early and treated, chances of glaucoma are greatly reduced. Sufferers are often advised not to engage in high-impact sports such as long-distance running or martial arts, as strong impacts can cause more pigment cells to slough off

Q:What does the word pigment mean?

it means the color. like the pigment of your eyes could be green, blue, hazel. or the pigment of your skin. it's a fancy-pants word for color.

Q:thank you very much for your help!

Well photosynthetic pigments has to do with the different component of light (i.e. the colors - ROYGBIV) and their specific wavelenght. Photosynthetic pigments based on their colors can capture the energy from that wavelenght. For example fucoxanthin can capture the brown color of the light just like phycocyanin can capture the blue color of the light. These photosynthetic pigments are usually the accessory pigments of Chlorophyll A which is the main pigments of most of the photosynthetic organisms in the earth.

Q:What does pigment mean?

* PIGMENT [uncountable and countable] = a natural substance that makes skin, hair, plants etc a particular colour. ==> Melanin is the dark brown pigment of the hair, skin and eyes. ==> The artist Sandy Lee uses natural pigments in her work. ( Longman Dictionary ) * PIGMENT = the natural colouring matter of animal or plant tissue. ==> Carotenoid pigments are red, orange, or yellow. ( Oxford Dictionary ) * PIGMENT = a substance used for colouring or painting, especially a dry powder, which when mixed with oil, water, or another medium constitutes a paint or ink. ==> All the frescoes are painted with earth pigments ( Oxford Dictionary )

Q:What are MAC eyeshadow pigments? Are they just like regular eyeshadow.. are they used the same way? Has anyone tried them and liked them?

Q:Compare and contrast pigment color with the color seen from a light. What is the difference between mixing pigment colors and mixing light colors?

you notice pigments the colour you notice them, using fact they replicate a spectra of sunshine, with particular frequencies, and take up all others seen to the human eye. in case you combine distinctive monochromatic mild with distinctive colours (as seen on the television: purple, green and blue it quite is referred to as additive mixing, or magenta, yellow and cyanide that's the different technique) your retina will upload the colors up, and experience it as a distinctive shade. (by skill of including each and all of the three colours on an identical intensity, you are able to create white mild) while mixing pigments (they are chemical compounds) you get a clean cloth, which will replicate an different spectra of sunshine, which you will see as a shade

Q:So i'm writing up a lab report and i'm just a little confused on why scarlet, rosy, cinnabar and vermillion mutants contain the same kinds and amounts of pigments found in wild-type according to paper chromatography. Since they're mutants shouldn't it be different? I don't understand how i'm going to explain that they are mutants when it appears that they have the same phenotype as wild-type. Thank you so much for your help!

Man pigments determine the colour of the eye. If the composition of pigments is same in all the flies,how can the colour in which their eyes look differ?isn't this a contradiction?i suspect the accuracy of The chromatography test because even a very very slight change in the amount of pigment can significantly change the colour. The phenotype is always different in mutants due to different genotype. in genotype is taken for granted if a change in phenotype is present. Wait just got over into a nice point. Sometimes even if the pigment composition being same different colours m8 be produced due to different allotropes or iro of the same pigment might have different colours!though allotropes(not isomers) have same composition but differ in,their post translational changes r different.since post translational changes r indirectly influenced by genes.this completely explains this case.

Q:What happens to the yellow pigments in a leaf during the summer months?

in case you may surely ask a query like that, then it sounds to me such as you opt to have intercourse with one in all your instructors. enable me be the 1st to tell you that it will no longer take place! She's/he's have been given a husband/spouse to do each and all the grimy paintings for her/him! you're basically a pupil and that's a criminal offense in each and each state for a instructor to have something for a minor! Have had a weigh down on a instructor, definite that's a load of bull-****, yet that's the way life is and we the two might desire to provide up dreaming and locate ourselves a hoe which will please us in each way conceivable! that's effective to appreciate that somebody else has wandered that. % me as suited answer on account which you and that i've got lots in worry-loose!

Q:a. chlorophyll ab. chlorophyll bc. chlorophyll cd. carotenoid pigments

Chlorophylls are greenish pigments which contain a porphyrin ring. This is a stable ring-shaped molecule around which electrons are free to migrate. Because the electrons move freely, the ring has the potential to gain or lose electrons easily, and thus the potential to provide energized electrons to other molecules. This is the fundamental process by which chlorophyll captures the energy of sunlight. There are several kinds of chlorophyll, the most important being chlorophyll a. This is the molecule which makes photosynthesis possible, by passing its energized electrons on to molecules which will manufacture sugars. All plants, algae, and cyanobacteria which photosynthesize contain chlorophyll a. A second kind of chlorophyll is chlorophyll b, which occurs only in green algae and in the plants. A third form of chlorophyll which is common is (not surprisingly) called chlorophyll c, and is found only in the photosynthetic members of the Chromista as well as the dinoflagellates. The differences between the chlorophylls of these major groups was one of the first clues that they were not as closely related as previously thought. Carotenoids are usually red, orange, or yellow pigments, and include the familiar compound carotene, which gives carrots their color. These compounds are composed of two small six-carbon rings connected by a chain of carbon atoms. As a result, they do not dissolve in water, and must be attached to membranes within the cell. Carotenoids cannot transfer sunlight energy directly to the photosynthetic pathway, but must pass their absorbed energy to chlorophyll. For this reason, they are called accessory pigments. One very visible accessory pigment is fucoxanthin the brown pigment which colors kelps and other brown algae as well as the diatoms. From this I would say the answer is c.
