- Q: I need to find powdered paint or pigment that I can throw, for some photographs.Preferably cheap, and that wouldn't stain skin.I've looked into powder paint, though this tends to stain skin for about a week.Thanks :)
- Wear protective gloves if you don't want your hands stained. You should also be concerned because many pigments have toxic chemicals that can absorb through the skin.
- Q: thank you very much for your help!
- it gives nutrients to the plantsfood to all the parts of the plants.
- Q: i love makeup so mucch im like addicted...lol but the only thing is that i only buy that department or drug store brands cause i cannot afford high quality brands. the one that i buy are good for me,,but anyways i was wondering what the heck is mac eyepigment,,what is the diffrence between eyeshow and pigment? pleas help thank u,,,oh yeah and what does it look,like on the eyes?
- Mac pigments are great to use if you love makeup like myself. I use this one called frost and it's great for mixing your eyeshadows, as a highlighter, and even mix it with your lipstick or lip glosses. This other one i have is pot of gold or something like that , but i mainly use it on my eyes and maybe a lil with my lip gloss. It's has a shimmer look to it, so a little goes a long way, but it's pretty much versitile. I also use pigment by loreal and i like the colors it does work , but not as good as Mac, but the you need to spend some money on good makeup brushes , that way you it will go on evenly and won't make you look like a racoon. Hope this helps
- 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: why light and pigments are different?
- A pigment is a material that changes the color of reflected or transmitted light as the result of wavelength-selective absorption. This physical process differs from fluorescence, phosphorescence, and other forms of luminescence, in which a material emits light. Many materials selectively absorb certain wavelengths of light. Materials that humans have chosen and developed for use as pigments usually have special properties that make them ideal for coloring other materials. A pigment must have a high tinting strength relative to the materials it colors. It must be stable in solid form at ambient temperatures. For industrial applications, as well as in the arts, permanence and stability are desirable properties. Pigments that are not permanent are called fugitive. Fugitive pigments fade over time, or with exposure to light, while some eventually blacken. Pigments are used for coloring paint, ink, plastic, fabric, cosmetics, food and other materials. Most pigments used in manufacturing and the visual arts are dry colourants, usually ground into a fine powder. This powder is added to a vehicle (or binder), a relatively neutral or colorless material that suspends the pigment and gives the paint its adhesion.
- 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: i want to get mac melon pigment but i dont know what other eyeshadows to pair and blend it with. im looking for an everyday look. also what brushes to use with pigments?
- With the Melon pigment, I would recommend using warm, chocolate copper, bronze types of colors. It will provide a nice contrast to the melon while giving your eyes some added depth and definition. As far as brushes go, I like using the 252, large shader brush. This brush picks up pigment nicely and it has nice compressed/dense bristles so you can manipulate and lay the pigment down with greater ease. I like the #286 The dual fiber blending brush for pigments as well. It's made of natural fiber and synthetic fiber. This is a great brush because you really get 2 brushes in 1. With this 'blending' brush you can also use it for targeted color deposits and the synthetic fibers won't suck up what you just laid down and you will get a flawless, beautifully blended eyeshadow application.
- Q: how to prepare coloured pigments?
- Chemically, pigments fall into a number of large groups, but these are often arbitrarily divided into two major groups. The first group comprises pigments that contain nitrogen; it includes hemoglobins, chlorophylls, bile pigments, and dark-colored pigments called melanin, widespread in many animal groups and the chemical that is responsible for variations in the color of human skin. Related to melanins are the indigoids, of which the well known plant pigment indigo is an example. Riboflavin, which is also known as vitamin B12, is one of a number of pale yellow to green pigments that are produced by several plant groups. The second group is formed of pigments without nitrogen. Carotenoids are members of this group, as are the important plant pigments called flavonoids. In leaves, flavonoids selectively admit light wavelengths that are important to photosynthesis, while blocking out ultraviolet light, which is destructive to cell nuclei and proteins. Flavonoids are also important in flower color, in particular providing red and blue pigments. Bright fall colors are produced by the conversion of colorless flavonoids, called flavonols, into colored forms, called anthocyanins. Quinones provide many yellow, red, and orange pigments, including several useful dyes derived from insects that feed on plants containing the quinones. Cochineal, for example, is a red pigment obtained from the fat cells of scale insects that feed on cactus plants.
- Q: Hi what is pigment?i went on mac cosmetics and they sell all different kinds of stuff called pigment. I want to use it to make lip gloss but is it safe for my lips?please answer soon!
- pigment is just color. the color shown or what makes a color. MAC is GREAT!!!!! its a color used to product a color or the actual color itself. either way....pigment means color.
- Q: what is the difference between light color and pigment colors?
- Pigments are chemicals that selectively absorb and reflect different spectra of light. When a surface is painted with a pigment, light hitting the surface is reflected, minus some wavelengths. This subtraction of wavelengths produces the appearance of different colors. Most paints are a blend of several chemical pigments, intended to produce a reflection of a given color.
