El vidrio no templado contiene burbujas de aire microscópicas que se expanden y contraen a medida que el vidrio se calienta y enfría, especialmente a temperaturas extremas como durante el enlatado y la congelación. Cuando esas pequeñas burbujas de aire se expanden, hacen que el vidrio se rompa o incluso explote. Espero que esto haya ayudado, por favor, dé cinco estrellas y mentalmente.
Answer:
Yes, if there is a mutation in the operator of the lac operon in a cell such that the lac repressor always stays bound to the operator. If lactose is added to the cell, the lac repressor loses its ability to bind DNA. It clear off the operator, clearing the way for RNA polymerase to transcribe the operon.

Explanation:
Positive Feedback Loop
The direction is maintained, not changed, so this is positive feedback. Another example of positive feedback is uterine contractions during childbirth. The hormone oxytocin, made by the endocrine system, stimulates the contraction of the uterus. This produces pain sensed by the nervous system.
