Stress hormones are produced by the adrenal glands in response to signals from the brain.
Now, researchers at the University of Maryland have shown that the most successful male suitors tone down their mating displays in response to signals from the females.
Upon arriving at their final destination, they begin to differentiate, in response to signals from the immediate surroundings, which activate a genetic program that causes each to acquire the properties of a specific subtype of neuron.
Now the controller can be made to operate automatically as before or in response to signals it receives over telephone lines or through wireless devices or, if it is connected to a computer, over the Internet.
Otherwise, the nearby handset will drown out the more distant handset's signal.To prevent this, CDMA handsets adjust their power output 800 times per second in response to signals from nearby base-stations.
Bonnie Bassler, a molecular biologist at Princeton University, has recently shown that it is through quorum sensing that cholera bacteria are able to accumulate in the intestines and release toxins that can be fatal; Pseudomonas is also known to switch on its virulence genes in response to signals from quorum sensing.
The system of synthesis has to generate sounds in response to signals emitted by the particle detection system.
MØs and other phagocytic cells (e.g., neutrophils and T-cells) can rapidly be recruited to the airspaces in response to signals from the pneumocytes or other sources.
The YfiBNR system contains three protein members and modulates intracellular c-di-GMP levels in response to signals received in the periplasm (Malone et al., 2010).
Cells in the pituitary that synthesize luteinizing and follicle-stimulating hormones regulate the relative production of these two key reproductive hormones in response to signals from the hypothalamus.
Embryonic and fetal myoblasts are committed to the myogenic fate during somitogenesis in response to signals from adjacent tissues including the mesoderm and notochord.
