  2. Energy level - Wikipedia

    en.wikipedia.org/wiki/Energy_level

    If it is at a higher energy level, it is said to be excited, or any electrons that have higher energy than the ground state are excited. Such a species can be excited to a higher energy level by absorbing a photon whose energy is equal to the energy difference between the levels. Conversely, an excited species can go to a lower energy level by ...

  3. Diffusion - Wikipedia

    en.wikipedia.org/wiki/Diffusion

    Three-dimensional rendering of diffusion of purple dye in water. Diffusion is the net movement of anything (for example, atoms, ions, molecules, energy) generally from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in Gibbs free energy or chemical potential.

  4. Tic-tac-toe variants - Wikipedia

    en.wikipedia.org/wiki/Tic-tac-toe_variants

    Tic-tac-toe is an instance of an m,n,k-game, where two players alternate taking turns on an m × n board until one of them gets k in a row. [1] Harary's generalized tic-tac-toe is an even broader generalization. The game can also be generalized as a n d game. [2] The game can be generalised even further from the above variants by playing on an ...

  5. Spreadsheet - Wikipedia

    en.wikipedia.org/wiki/Spreadsheet

    A spreadsheet is a computer application for computation, organization, analysis and storage of data in tabular form. [1][2][3] Spreadsheets were developed as computerized analogs of paper accounting worksheets. [4] The program operates on data entered in cells of a table. Each cell may contain either numeric or text data, or the results of ...

  6. Microsoft Excel - Wikipedia

    en.wikipedia.org/wiki/Microsoft_Excel

    Microsoft Excel is a spreadsheet editor developed by Microsoft for Windows, macOS, Android, iOS and iPadOS. It features calculation or computation capabilities, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications (VBA). Excel forms part of the Microsoft 365 suite of software.

  7. Remote sensing atmospheric boundary layer - Wikipedia

    en.wikipedia.org/wiki/Remote_sensing_atmospheric...

    The use of satellite derived boundary layer heights provides another method for verifying climate model output. Some remote sensing instruments have limitations. Since CALIOP relies on the use of backscattered light, daytime retrievals can contain high signal to noise ratios as sunlight can add background noise.

  8. Vascular tissue - Wikipedia

    en.wikipedia.org/wiki/Vascular_tissue

    Vascular tissue is a complex conducting tissue, formed of more than one cell type, found in vascular plants. The primary components of vascular tissue are the xylem and phloem. These two tissues transport fluid and nutrients internally. There are also two meristems associated with vascular tissue: the vascular cambium and the cork cambium.

  9. Allele frequency - Wikipedia

    en.wikipedia.org/wiki/Allele_frequency

    Allele frequency. Allele frequency, or gene frequency, is the relative frequency of an allele (variant of a gene) at a particular locus in a population, expressed as a fraction or percentage. [1] Specifically, it is the fraction of all chromosomes in the population that carry that allele over the total population or sample size.
