  2. Moder humus - Wikipedia

    en.wikipedia.org/wiki/Moder_humus

    Moder humus form may include only the Ah horizon or ectorganic horizons below end- organic horizons. [2] Fine humus elements have permeated the mineral soil on this horizon. Although soil animals may carry organic matter into the upper region of this horizon, this will only happen over a short distance. [ 2 ]

  3. Mor humus - Wikipedia

    en.wikipedia.org/wiki/Mor_humus

    Mor humus is a form of forest floor humus occurring mostly in coniferous forests. [1] Mor humus consists of evergreen needles and woody debris that litter the forest floor. This litter is slow to decompose , in part due to their chemical composition (low pH, low nutrient content), but also because of the generally cool and wet conditions where ...

    The formation of mull humus form results from various factors, including regional climate, parent rock, vegetation, and soil organism. [3] Mull order presents in deciduous forests, and the development is often associated with a mild climate in terms of warm temperature and moderate precipitation, also rich soil parent materials.

    HTML Form format HTML 4.01 Specification since PDF 1.5; HTML 2.0 since 1.2 Forms Data Format (FDF) based on PDF, uses the same syntax and has essentially the same file structure, but is much simpler than PDF since the body of an FDF document consists of only one required object. Forms Data Format is defined in the PDF specification (since PDF 1.2).

  6. Mid-ocean ridge - Wikipedia

    en.wikipedia.org/wiki/Mid-ocean_ridge

    A mid-ocean ridge (MOR) is a seafloor mountain system formed by plate tectonics. It typically has a depth of about 2,600 meters (8,500 ft) and rises about 2,000 meters (6,600 ft) above the deepest portion of an ocean basin. This feature is where seafloor spreading takes place along a divergent plate boundary. The rate of seafloor spreading ...

    for every two objects A and B a set Mor(A,B) of things called morphisms from A to B. If f is in Mor(A,B), we write f : A → B. for every three objects A, B and C a binary operation Mor(A,B) × Mor(B,C) → Mor(A,C) called composition of morphisms. The composition of f : A → B and g : B → C is written as g ∘ f or gf. (Some authors write ...

  8. Morphogenesis - Wikipedia

    en.wikipedia.org/wiki/Morphogenesis

    Morphogenesis also describes the development of unicellular life forms that do not have an embryonic stage in their life cycle. Morphogenesis is essential for the evolution of new forms. Morphogenesis is a mechanical process involving forces that generate mechanical stress, strain, and movement of cells, [ 1 ] and can be induced by genetic ...

  9. Morphology (linguistics) - Wikipedia

    Generally, a lexeme is a set of inflected word-forms that is often represented with the citation form in small capitals. [8] For instance, the lexeme eat contains the word-forms eat, eats, eaten, and ate. Eat and eats are thus considered different word-forms belonging to the same lexeme eat.
