Description of LED Fluorescent:

Many phosphors(Florescent Powder) tend to lose efficiency gradually by several mechanisms. The activators can undergo change of valence (usually oxidation), thecrystal lattice degrades, atoms – often the activators – diffuse through the material, the surface undergoes chemical reactions with the environment with consequent loss of efficiency or buildup of a layer absorbing either the exciting or the radiated energy, etc.


Festures of LED Fluorescent:

Phosphor layers provide most of the light produced by fluorescent lamps, and are also used to improve the balance of light produced by metal halide lamps. Various neon signs use phosphor layers to produce different colors of light. Electroluminescent displays found, for example, in aircraft instrument panels, use a phosphor layer to produce glare-free illumination or as numeric and graphic display devices. White LED lamps consist of a blue or ultra-violet emitter with a phosphor coating that emits at longer wavelengths, giving a full spectrum of visible light.

Q: Are carontenoids and anythocyanin accesory pigments.
Accessory Pigments
Q: Why does a plant use several pigments instead of one or two?Why are plant leaves green?
Pigments are a way for a plant to absorb the sun's energy in the form of light (photosynthesis). The different colored pigments absorb different wavelengths of light and pass it on directly to the plant to make energy, except for one class called the carotenoids, which much pass it on the the chlorophyll before anything happens The plants leaves are green because they absorb all the other wavelengthss (red, blue, oragne etc) except the green one, and the reflection of the green is what our eyes see.
Q: Please help me answer these Genetics problems. These are the problems that was assigned in the previous exams, but the professor doesn't provide the answer keys or a review session to go over these.Pigment in the mouse is produced only when the C allele is present. Individuals of the cc genotype have no color. if color is present, it may be determined by the A, a alleles. AA or Aa results in the agouti color, while aa results in the black color. In 3 crosses between agouti females whose genotypes are unknowns and males of the aacc genotype, the following phenotypic ratios were obtained. Female 1: 8 agouti 8 colorlessFemale 2: 4 agouti 5 black 10 colorless
interior the 1st bypass AACC x aacc, discern a million will produce all AC gametes and discern 2 ac. Your F1 will all be AaCc. As all have the C allele they are going to be pigmented and as they're Aa they're going to all be agouti. Your F1 bypass is AaCc x AaCc. each and each discern can produce 4 gametes AC, Ac, aC, ac. To get all the genotypes you would be able to desire to entice a 4 x 4 Punnett sq.. each and each column and each and each row has between the 4 gametes in it and the cells comprise the blended genotypes. in case you count type up your genotypes you will discover 9 comprise the two A and C, those are agouti, 4 comprise cc, and all of those would be white regardless of the genotype at A, 3 comprise aa and C, those will all be black. So your phenotypic ratio would be 9:4:3 agouti: white: black the subsequent 3 crosses are all attempt crosses - you employ a recessive discern to artwork out the genotype of the different discern. a million. As lots of the offspring are colourless, you be attentive to that the two mothers and dads carry the c allele, as you pick cc for colourless mice. As there are no black mice, there is not any a allele interior the mum, as no aa offspring are produced. The bypass is AACc x aacc. woman gametes are AC or Ac and male gametes are all ac, offspring are the two AaCc or Aacc. 2. Is the opposite of bypass a million. There are black offspring so mom would desire to hold an a allele to furnish black mice, as there are no colourless ones, there is not any c allele interior the mum. you could write down the bypass and the F2 effect now. 3. This time all hues are produced, so the mum would desire to hold the two a and c alleles. Her genotype is AaCc, she would be able to offer 4 gametes as interior the 1st bypass and you will artwork out the resultant genotypes and phenotypes interior the F2.
Q: What does the word pigment mean?
pigment - a substance that gives color to something like paint or ink. Natives used charcoal as a pigment to make dyes. Also: a substance that occurs in Nature which gives color to, say, flowers or skin. Mellanin is a pigment in our bodies that gives our skin color. Albino people have no pigment in their skin and so their skin appears very white and pinkish from the color of the blood in the blood vessels. It's not rare at all to see this word used as a noun, but it can be used as a verb meaning to add a substance to give something color.
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 anyone know its chemical formula or constituents ?
Epona's answer is extremely sturdy. in case you seem up colour institutions you will locate diverse institutions reckoning on who has written them and what structures they're drawing from. yet you'll be able to desire to continually use institutions that make experience to you. case in point - you will in all probability locate that easy blue is the colour linked with peace. yet reckoning on what form of peace you're going for you may go with a diverse colour. possibly purple if that is for peace in the kin or with acquaintances, pink if that is religious in nature, or eco-friendly if that is physique appropriate. The institutions I genuinely tend to circulate with are: pink - lust, action, means, braveness Orange - creativity, braveness, means (extra innovative form than the pink). Yellow - issues bearing on the concepts (like possibly you have have been given a attempt to earnings for) or psychological suggestion. easy eco-friendly - prosperity darkish eco-friendly - therapeutic easy Blue - peace, tranquility darkish Blue - desires, on occasion suggestion pink - issues coping with the religious White - purification and can be a stand in for extremely just about something Black - liberating negativity, banishing purple - love, friendship, kin i do no longer think there is any colour that would desire to be prevented. yet I often use a diverse affiliation than what i've got listed. And my institutions are in user-friendly terms valid for yet somebody else in the event that they make experience to them. i exploit white candles maximum many times as I continually have them handy and that they might continually be spiced up with diverse oils this is something I do very often.
Q: a question on my photosynthesis test review...=_=
How Pigments Work
Q: thinking about the main role of pigments in photosynthesis...? explain how the pigments in colored objects suc?
photosynthetic pigment or antenna pigment is a pigment that is present in chloroplasts or photosynthetic bacteria and captures the light energy necessary for photosynthesis. Green plants have five closely-related photosynthetic pigments (in order of increasing polarity): Carotene - an orange pigment Xanthophyll - a yellow pigment Chlorophyll a - a blue-green pigment Chlorophyll b - a yellow-green pigment Phaeophytin a[1] - a gray-brown pigment Phaeophytin b[1] - a yellow-brown pigment Chlorophyll a is the most common of the six, present in every plant that performs photosynthesis. The reason that there are so many pigments is that each absorbs light more efficiently in a different part of the spectrum. Chlorophyll a absorbs well at a wavelength of about 400-450 nm and at 650-700 nm; chlorophyll b at 450-500 nm and at 600-650 nm. Xanthophyll absorbs well at 400-530 nm. However, none of the pigments absorbs well in the green-yellow region, which is responsible for the abundant green we see in nature.
Q: what roles do pigments have in energy transfer?
Pigments okorder /... When a photon of just the right amount of energy strikes an electron resonating in the pigment, the electron can absorb the photon and get promoted to a higher quantum level. The photon must have just the exact amount of energy to boost the electron from its current level to its new level or it cannot be absorbed. If the incoming photon is just right to promote an electron, in that pigment, the newly energized electron resonates along the bonds at the higher energy level where it can pass to the photosynthetic reaction center from the pigment array, to split water and take back an electron. Meanwhile the chlorophyll's electron passes to the electron transport chain to begin oxidative phophorylation.
Q: light absorption, which pigments are involved?
All photosynthetic organisms contain one or more organic pigments capable of absorbing visible radiation, which will initiate the photochemical reactions of photosynthesis. The three major classes of pigments found in plants and algae are the chlorophylls, the carotenoids and the phycobilins. Carotenoids and phycobilins are called accessory pigments since the quanta (packets of light) absorbed by these pigments can be transferred to chlorophyll. Chlorophylls chlorophyll a - present in all higher plants and algae chlorophyll b - present in all higher plants and green algae chlorophyll c - diatoms and brown algae chlorophyll d - red algae (chlorophyll a is present in all photosynthetic organisms that evolve O2.) Chlorophyll molecules contain a porphyrin 'head' and a phytol 'tail'. The polar (water-soluble) head is made up of a tetrapyrrole ring and a magnesium ion complexed with the nitrogen atoms of the ring. The phytol tail extends into the lipid layer of the thylakoid membrane. Carotenoids (carotenes and xanthophylls) Carotenes: -carotene - higher plants and most algae $-carotene - most plants some algae xanthophylls: luteol, fucoxanthol and violaxanthol Carotenoids contain a conjugated double bond system of the polyene type (C-C=C-C=C). Energy absorbed by carotenoids may be transferred to chlorophyll a for photosynthesis. Phycobilins (found mostly in red and blur-green algae): phycoerythrin phycocyanin allophycocyanin )
