  2. Gravitational biology - Wikipedia

    en.wikipedia.org/wiki/Gravitational_biology

    Gravitational biology is the study of the effects gravity has on living organisms. Throughout the history of the Earth life has evolved to survive changing conditions, such as changes in the climate and habitat. However, one constant factor in evolution since life first began on Earth is the force of gravity.

  3. Gravitropism - Wikipedia

    en.wikipedia.org/wiki/Gravitropism

    Other examples of gravitropic mutants include those affecting the transport or response to the hormone auxin. [10] In addition to the information about gravitropism which such auxin-transport or auxin-response mutants provide, they have been instrumental in identifying the mechanisms governing the transport and cellular action of auxin as well ...

  4. Gravitaxis - Wikipedia

    en.wikipedia.org/wiki/Gravitaxis

    Gravitaxis (or geotaxis [1]) is a form of taxis characterized by the directional movement of an organism in response to gravity. [2] There are a few different causes for gravitaxis. Many microorganisms have receptors like statocysts that allow them to sense the direction of gravity and to adjust their orientation accordingly. However ...

    en.wikipedia.org/wiki/Animal_locomotion_on_the...

    Biolocomotion is generally characterized by the transfer of muscular strain energy to the kinetic and gravitational potential energy of the creature, and the kinetic energy of the suspending fluid. In contrast, meniscus climbing has a different energy pathway: by deforming the free surface, the insect converts muscular strain to the surface ...

    A wheeled buffalo figurine—probably a children's toy—from Magna Graecia in archaic Greece [1]. Several organisms are capable of rolling locomotion. However, true wheels and propellers—despite their utility in human vehicles—do not play a significant role in the movement of living things (with the exception of the corkscrew-like flagella of many prokaryotes).

  7. Statocyst - Wikipedia

    en.wikipedia.org/wiki/Statocyst

    Drawing of the statocyst system Statocysts (ss) and statolith (sl) inside the head of sea snail Gigantopelta chessoia. The statocyst is a balance sensory receptor present in some aquatic invertebrates, including bivalves, [1] cnidarians, [2] ctenophorans, [3] echinoderms, [4] cephalopods, [5] [6] crustaceans, [7] and gastropods, [8] A similar structure is also found in Xenoturbella.

  8. Biological pump - Wikipedia

    en.wikipedia.org/wiki/Biological_pump

    Biology, physics and gravity interact to pump organic carbon into the deep sea. The processes of fixation of inorganic carbon in organic matter during photosynthesis, its transformation by food web processes (trophodynamics), physical mixing, transport and gravitational settling are referred to collectively as the biological pump.

  9. Biological motion - Wikipedia

    en.wikipedia.org/wiki/Biological_motion

    For instance, a well known example of sensitiveness to a specific type of biological motion is expert dancers observing others dancing. Compared to people who do not know how to dance, expert dancers show more sensitiveness to the biological motion from the dance style of their expertise. The same expert dancer would also show similar but less ...
