Which is an element of negative feedback?
Maintains stability.
Encourages change.
Produces change.
Improves the system.
The Correct Answer is A
Maintains stability: Negative feedback in a system is a regulatory mechanism that helps maintain stability and homeostasis. When a deviation occurs from a set point, negative feedback mechanisms work to bring the system back to its normal state, thus maintaining stability.
Encourages change: Negative feedback doesn't encourage change; rather, it resists change and maintains the status quo.
Produces change: Positive feedback mechanisms produce change by amplifying the initial deviation from the normal state, while negative feedback works to counteract these deviations and restore stability.
Improves the system: While negative feedback maintains stability, whether it improves the system or not depends on the context. It can be beneficial for maintaining internal balance, but in some cases, it might not necessarily lead to system improvement, especially if the system is functioning optimally already.

Living related donors: These are individuals who are biologically related to the recipient, such as parents, siblings, or children. They can donate organs like kidneys or portions of the liver.
Living unrelated donors: These are individuals who are not biologically related to the recipient but are willing to donate an organ while alive, typically through altruistic or paired exchange programs. This could include friends or unrelated individuals who are a match.
Cadaver donors (Deceased donors): These are individuals who have passed away, and their organs and tissues can be donated for transplantation. Deceased donors can provide organs like hearts, lungs, kidneys, liver, pancreas, and tissues like corneas, bones, and skin after death.
