What is positive feedback?Positive feedback is a mechanism that increases or amplifies the series of reaction that is affected and influenced by its own results and processes. The output signal of the series act as an amplifying factor.
The nerve signals act as positive feedback by increasing the channels by a small amount of sodium that leads to an action potential, in the neurons to increase the disruptive influences.
The sodium ion of the nerve signaling causes the positive feedback loop to increase the ions entering the neurons which leads to more potential to be created.

“Quality of life differs from family to family”. Justify with example.
please help me
Answer:
Quality of life differs from individual to individual. It may be taken as family to family to absorb slight variations in individual’s routines. Every person has a say, though there is limited freedom. There are bondages, checks and balances and responses to them in a different way create a visible quality and activity change.
I usually attribute that to the limited (or partial) free will afforded to us by the Creator. That is how He would gauge our performances and possibly clamp approvals or otherwise to every individual performance. That brings in the concept of hell and heaven (limited to those only who believe). Rest: Allah knows best.
;))The quality of life differs from family to family for the following reasons:
Income and Wealth of families differ : All things been equal, a family that earns a higher income would have a higher quality of life. This is because such a family would be able to afford basic amenities and luxuries.
For example, consider two families. One of the families earn $10,000 per month and the other family earns $200 per month. The family that earns a higher income would be able to live a more comfortable life and thus their quality of life would be better
Genetics of family differ: A family that has a history of a chronic disease would live a lower quality of life when compared to a family that has no such disease.
For example, a family that suffers from sickle cell anaemia would live a lower quality of family when compared to a family that does not suffer from this disease.
Quality of life measures the degree to which a person or family is comfortable, healthy and happy.
