Passive transport — means moving biochemicals and other atomic or molecular substances across membranes. Unlike active transport, this process does not involve chemical energy, because, unlike in an active transport, the transport across membrane is always coupled… … Wikipedia
Passive immunity — is the transfer of active humoral immunity in the form of readymade antibodies, from one individual to another. Passive immunity can occur naturally, when maternal antibodies are transferred to the fetus through the placenta, and can also be… … Wikipedia
Passive radar — systems (also referred to as passive coherent location and passive covert radar) encompass a class of radar systems that detect and track objects by processing reflections from non cooperative sources of illumination in the environment, such as… … Wikipedia
Passive smoking — is the involuntary inhalation of smoke from tobacco products. It occurs when tobacco smoke permeates any environment, causing its inhalation by all people within that environment. Such smoke is called secondhand smoke (SHS) or environmental… … Wikipedia
active transport — n movement of a chemical substance by the expenditure of energy against a gradient in concentration or electrical potential across a plasma membrane * * * (in biochemistry) an energy dependent process in which certain substances (including ions,… … Medical dictionary
Cell migration — is a central process in the development and maintenance of multicellular organisms. Tissue formation during embryonic development, wound healing and immune responses all require the orchestrated movement of cells in a particular direction to a… … Wikipedia
Active sensory systems — are sensory receptors that are activated by probing the environment with self generated energy. Examples include echolocation of bats and dolphins and insect antennae. Using self generated energy allows more control over signal intensity,… … Wikipedia
