  2. Bioart - Wikipedia

    en.wikipedia.org/wiki/BioArt

    Regenerative Reliquary (2016) by American bioartist Amy Karle.Human stem cells were grown to form bone over a preformed hydrogel scaffold in the shape of a hand.. Bioart is an art practice where artists work with biology, live tissues, bacteria, living organisms, and life processes.

  3. Kinesis (biology) - Wikipedia

    en.wikipedia.org/wiki/Kinesis_(biology)

    The kinesis strategy controlled by the locally and instantly evaluated well-being can be described in simple words: Animals stay longer in good conditions and leave bad conditions more quickly. If the well-being is measured by the local reproduction coefficient then the minimal reaction-diffusion model of kinesis can be written as follows: [ 3 ]

  4. Cytoplasmic streaming - Wikipedia

    en.wikipedia.org/wiki/Cytoplasmic_streaming

    It is usually observed in large plant and animal cells, greater than approximately 0.1 mm [vague]. In smaller cells, the diffusion of molecules is more rapid, but diffusion slows as the size of the cell increases, so larger cells may need cytoplasmic streaming for efficient function. [1]

  5. Anomalous diffusion - Wikipedia

    en.wikipedia.org/wiki/Anomalous_diffusion

    It has been found that equations describing normal diffusion are not capable of characterizing some complex diffusion processes, for instance, diffusion process in inhomogeneous or heterogeneous medium, e.g. porous media. Fractional diffusion equations were introduced in order to characterize anomalous diffusion phenomena.

  6. The Evolution of Beauty - Wikipedia

    en.wikipedia.org/wiki/The_Evolution_of_Beauty

    The Evolution of Beauty: How Darwin's Forgotten Theory of Mate Choice Shapes the Animal World—and Us is a 2017 book by the ornithologist and evolutionary biologist Richard O. Prum about the power of aesthetic mate choice, arguing it to be an important independent agent in evolution.

  7. Aquatic respiration - Wikipedia

    en.wikipedia.org/wiki/Aquatic_respiration

    In very small animals, plants and bacteria, simple diffusion of gaseous metabolites is sufficient for respiratory function and no special adaptations are found to aid respiration. Passive diffusion or active transport are also sufficient mechanisms for many larger aquatic animals such as many worms, jellyfish, sponges, bryozoans and similar ...

  8. Glucose uptake - Wikipedia

    en.wikipedia.org/wiki/Glucose_uptake

    Facilitated Diffusion is a passive process that relies on carrier proteins to transport glucose down a concentration gradient. [ 2 ] Secondary Active Transport is transport of a solute in the direction of increasing electrochemical potential via the facilitated diffusion of a second solute (usually an ion, in this case Na + ) in the direction ...

  9. Cell adhesion - Wikipedia

    en.wikipedia.org/wiki/Cell_adhesion

    Schematic of cell adhesion. Cell adhesion is the process by which cells interact and attach to neighbouring cells through specialised molecules of the cell surface. This process can occur either through direct contact between cell surfaces such as cell junctions or indirect interaction, where cells attach to surrounding extracellular matrix, a gel-like structure containing molecules released ...
