  2. Color charge - Wikipedia

    en.wikipedia.org/wiki/Color_charge

    Color charge is a property of quarks and gluons that is related to the particles' strong interactions in the theory of quantum chromodynamics (QCD). Like electric charge, it determines how quarks and gluons interact through the strong force; however, rather than there being only positive and negative charges, there are three "charges", commonly called red, green, and blue.

  3. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    The dipoles do not cancel out, resulting in a net dipole. The dipole moment of water depends on its state. In the gas phase the dipole moment is ≈ 1.86 debye (D), [ 11 ] whereas liquid water (≈ 2.95 D) [ 12 ] and ice (≈ 3.09 D) [ 13 ] are higher due to differing hydrogen-bonded environments.

  4. Dipole - Wikipedia

    en.wikipedia.org/wiki/Dipole

    The linear molecule CO 2 has a zero dipole as the two bond dipoles cancel. Potassium bromide (KBr) has one of the highest dipole moments because it is an ionic compound that exists as a molecule in the gas phase. The bent molecule H 2 O has a net dipole. The two bond dipoles do not cancel. The overall dipole moment of a molecule may be ...

  5. Thorns, spines, and prickles - Wikipedia

    en.wikipedia.org/wiki/Thorns,_spines,_and_prickles

    Prickles on a blackberry branch. In plant morphology, thorns, spines, and prickles, and in general spinose structures (sometimes called spinose teeth or spinose apical processes), are hard, rigid extensions or modifications of leaves, roots, stems, or buds with sharp, stiff ends, and generally serve the same function: physically defending plants against herbivory.

  6. Azulene - Wikipedia

    en.wikipedia.org/wiki/Azulene

    Its dipole moment is 1.08 D, [6] in contrast with naphthalene, which has a dipole moment of zero. This polarity can be explained by regarding azulene as the fusion of a 6 π-electron cyclopentadienyl anion and a 6 π-electron tropylium cation : one electron from the seven-membered ring is transferred to the five-membered ring to give each ring ...

  7. Biological pigment - Wikipedia

    en.wikipedia.org/wiki/Biological_pigment

    It is the presence and relative abundance of chlorophyll that gives plants their green color. All land plants and green algae possess two forms of this pigment: chlorophyll a and chlorophyll b. Kelps, diatoms, and other photosynthetic heterokonts contain chlorophyll c instead of b, while red algae possess only chlorophyll a. All chlorophylls ...

    WADA pointed out that while both cases involved the same substance, the specific facts related to Barquero's case were “very different” to Sinner's. WADA explains reasons for different doping ...

  9. On Colors - Wikipedia

    en.wikipedia.org/wiki/On_Colors

    The sixth and final section of Aristotle's de Coloribus covers the color of man's and animals' skin, hair, and plumage (feathering). They act on a similar principle to that of plants. White hair occurs when the moister that possesses its own natural coloring dries up and black when the moister about the skin grows old without drying out because ...
