Bioinformatics
|
The use of computers, softwarem and mathematical mode=ls to process and integrate biological information from large data sets

|
Negative feedback
|
A primary mechanism of homeostasis, whereby a change in a physiological variable triggers a response hat counteracts the initial change.
|
|
|
Positive Feedback
|
A physiological control mechanism in which a change in a variabke triggers mechanisms that amplify the change.
