  2. Electroreception and electrogenesis - Wikipedia

    en.wikipedia.org/wiki/Electroreception_and...

    Electroreception and electrogenesis are the closely related biological abilities to perceive electrical stimuli and to generate electric fields. Both are used to locate prey; stronger electric discharges are used in a few groups of fishes (most famously the electric eel , which is not actually an eel but a knifefish ) to stun prey.

  3. Quorum sensing - Wikipedia

    en.wikipedia.org/wiki/Quorum_sensing

    In biology, quorum sensing or quorum signaling (QS) [1] is the process of cell-to-cell communication [2] that allows bacteria to detect and respond to cell population density by gene regulation, typically as a means of acclimating to environmental disadvantages.

    Advanced Placement (AP) Biology (also known as AP Bio) is an Advanced Placement biology course and exam offered by the College Board in the United States. For the 2012–2013 school year, the College Board unveiled a new curriculum with a greater focus on "scientific practices".

  5. Ampullae of Lorenzini - Wikipedia

    en.wikipedia.org/wiki/Ampullae_of_Lorenzini

    Ampullae of Lorenzini are physically associated with and evolved from the mechanosensory lateral line organs of early vertebrates.Passive electroreception using ampullae is an ancestral trait in the vertebrates, meaning that it was present in their last common ancestor. [7]

  7. Sense - Wikipedia

    en.wikipedia.org/wiki/Sense

    Sensory organs are organs that sense and transduce stimuli. Humans have various sensory organs (i.e. eyes, ears, skin, nose, and mouth) that correspond to a respective visual system (sense of vision), auditory system (sense of hearing), somatosensory system (sense of touch), olfactory system (sense of smell), and gustatory system (sense of taste).

  8. Fixed action pattern - Wikipedia

    en.wikipedia.org/wiki/Fixed_action_pattern

    Fixed action pattern" is an ethological term describing an instinctive behavioral sequence that is highly stereotyped and species-characteristic. [1] Fixed action patterns are said to be produced by the innate releasing mechanism, a "hard-wired" neural network , in response to a sign/key stimulus or releaser .

  9. Vestibular system - Wikipedia

    en.wikipedia.org/wiki/Vestibular_system

    T 1 is the characteristic time required for the cupula to accelerate until it reaches terminal velocity, and T 2 is the characteristic time required for the cupula to relax back to neutral position. The cupula has a small inertia compared to the elastic force (due to the jelly) and the viscous force (due to the endolymph), so T 1 is very small ...
