Question

What is the difference between negative feedback and positive feedback mechanisms? Negative feedback mechanisms return a system to a set point; positive feedback mechanisms amplify a response. Negative feedback mechanisms move a system away from a set point; positive feedback mechanisms stabilize a system at a set point. Negative feedback mechanisms stabilize a system at a set point; positive feedback mechanisms change the set point.

Answer 1

Postive Feedback encourages more of itself around to do the same.

Negative Feedback tries to negate itself in the hopes of reaching equalibrium.

Step-by-step explanation:

Postive Feedback modulates towards a specific state, amplifying the stimuli, all the while encouraging more of itself to amplify as well.

A fruit ripining discharges ethylee which cause more fruits around it to ripen as well, that's all fruits ripen relatively at the sime time.

Negative Feedback for example in homeostasis, brings about another response from the opposite side of its effect to balance it's effect, in other words the goal of homeostasis.

Answer 2

Feedback mechanism

Step-by-step explanation:

Negative feedback mechanisms return a system to a set point; positive feedback mechanisms amplify a response

Positive feedback mechanism

• A positive feedback mechanism occurs in nature when the product of a reaction leads to an increase in that reaction
• If one looks at a system in homeostasis, a positive feedback mechanism moves a system further away from the target of equilibrium and does this by amplifying the effects of a product or event and occurs when something needs to happen quickly

Negative feedback mechanism

• A negative feedback mechanism occurs in biology when the product of a reaction leads to a decrease in that reaction
• In this way, a negative feedback mechanism brings a system closer to a target of stability or homeostasis.
• Negative feedback mechanism helps in the maintenance of a steady, stable state
