there are many homeostatic systems which are maintained by feed back loops. a good example is red blood cell production (erythropoesis)
Negative Feedback Loops
Transfer RNA (tRNA) is a single strand that loops back on itself.
Negative
Knit two together through the back loops and Purl two together through the back loops
Trix, which was introduced back in 1954, whereas Froot Loops were introduced in 1966.

Loops were put on shirts to enable them to be hung on a hook. Over time, they became part of the style of the shirt.
Centered on the waistband, front and back, and centered on the center seam in the back, then about a hand-width from the fly on the front. If there are belt loops, either side of the back center loop, and either side of the frontmost loops.
Buckling a belt with 2 loops is actually quite simple. Just run the open end through the 2 loops and bring it back around through the second loop.
A: All current in a loop must return to the source. A source may feed many loops but all these loops current will return to the source as a collective. ----------- Series Circuit
