Modularity refers to the ability of a system to organize discrete, individual units that can overall increase the efficiency of network activity and, in a biological sense, facilitates selective forces upon the network.
A gap junction modulator is a compound or agent that either facilitates or inhibits the transfer of small molecules between biological cells by regulating gap junctions. [1] Various physiological processes including cardiac , neural or auditory , depend on gap junctions to perform crucial regulatory roles, and the modulators themselves are the ...
Allosteric regulation of an enzyme. In the fields of biochemistry and pharmacology an allosteric regulator (or allosteric modulator) is a substance that binds to a site on an enzyme or receptor distinct from the active site, resulting in a conformational change that alters the protein's activity, either enhancing or inhibiting its function.
Neuromodulation is the physiological process by which a given neuron uses one or more chemicals to regulate diverse populations of neurons. Neuromodulators typically bind to metabotropic, G-protein coupled receptors (GPCRs) to initiate a second messenger signaling cascade that induces a broad, long-lasting signal.
In evolutionary biology, a balanced lethal system is a situation where recessive lethal alleles are present on two homologous chromosomes. [1] Each of the chromosomes in such a pair carries a different lethal allele, which is compensated for by the functioning allele on the other chromosome. [ 1 ]
Kroger’s $25 billion proposed takeover of rival Albertsons ultimately failed because two judges – one federal and the other from the state of Washington – didn’t buy the competitive vision ...
The balance of nature, also known as ecological balance, is a theory that proposes that ecological systems are usually in a stable equilibrium or homeostasis, which is to say that a small change (the size of a particular population, for example) will be corrected by some negative feedback that will bring the parameter back to its original "point of balance" with the rest of the system.
This is great advice! Both methods are simple and effective. People left nearly 150 comments on American Standard K9's post. I laughed when one commenter shared, "My husband's Border Collie has 2 ...
