  2. Animal echolocation - Wikipedia

    en.wikipedia.org/wiki/Animal_echolocation

    Echolocation, also called bio sonar, is a biological active sonar used by several animal groups, both in the air and underwater. Echolocating animals emit calls and listen to the echoes of those calls that return from various objects near them. They use these echoes to locate and identify the objects.

  3. Electroreception and electrogenesis - Wikipedia

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

    In passive electrolocation, the animal senses the weak bioelectric fields generated by other animals and uses it to locate them. These electric fields are generated by all animals due to the activity of their nerves and muscles. A second source of electric fields in fish is the ion pump associated with osmoregulation at the gill membrane. This ...

  4. Magnetoreception - Wikipedia

    en.wikipedia.org/wiki/Magnetoreception

    In animals, the mechanism for magnetoreception is still under investigation. Two main hypotheses are currently being discussed: one proposing a quantum compass based on a radical pair mechanism, [2] the other postulating a more conventional iron-based magnetic compass with magnetite particles.

  5. Animal communication - Wikipedia

    en.wikipedia.org/wiki/Animal_communication

    Animals rely on signals called electrolocating and echolocating; they use sensory senses in order to navigate and find prey. [22] Signals are used as a form of commutation through the environment. Active signals or other types of signals influence receivers behavior and signals move quicker in distance to reach receivers.

  6. Cell–cell interaction - Wikipedia

    en.wikipedia.org/wiki/Cellcell_interaction

    In vertebrates, gap junctions are composed of transmembrane proteins called connexins. They form hexagonal pores or channels through which ions, sugars, and other small molecules can pass. Each pore is made of 12 connexin molecules; 6 form a hemichannel on one cell membrane and interact with a hemichannel on an adjacent cell membrane.

  7. Cell signaling - Wikipedia

    en.wikipedia.org/wiki/Cell_signaling

    In biology, cell signaling (cell signalling in British English) is the process by which a cell interacts with itself, other cells, and the environment. Cell signaling is a fundamental property of all cellular life in prokaryotes and eukaryotes. Typically, the signaling process involves three components: the signal, the receptor, and the effector.

  8. Cell (biology) - Wikipedia

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

    Cell metabolism is the process by which individual cells process nutrient molecules. Metabolism has two distinct divisions: catabolism, in which the cell breaks down complex molecules to produce energy and reducing power, and anabolism, in which the cell uses energy and reducing power to construct complex molecules and perform other biological ...
