Feedback Mechanism
What is Feedback Mechanism ( Closest answer can get it)
A process where a system responds to a change to maintain balance
What is Positive Feedback?
The response of a system that acts to increase the effect of any changes made to the system.
What is Negative Feedback ?
feedback mechanism that reverses a change to restore normal conditions
What term describes the maintenance of a stable internal environment in living organisms?
Homeostasis
Name the five main parts of a feedback mechanism shown in the skit.
Stimulus, Sensor, Integrator, Effector and Response
In baking, what gas produced by yeast causes bread to rise?
Carbon Dioxide
Why is the baking example a negative feedback mechanism
The oven temperature was corrected to fix the problem
Which organ plays a major role in maintaining body temperature and removing waste?
Skin
In the skit, what was the stimulus?
High Heat or The oven temperature being too high
How does yeast activity in bread show positive feedback?
As yeast produces CO₂, the dough becomes bigger, allowing the yeast to produce even more gas
What was the effector in the skit’s negative feedback loop?
Changing the oven temperature
Which internal condition must be kept within a narrow range for enzymes to function properly?
Body Temperature or PH
In the skit, what acted as the sensor?
Observing the flat bread
Why does yeast activity increase as the dough warms (but not too hot)?
Warmer temperatures speed up yeast metabolism, increasing CO₂ production
In the human body, what negative feedback response occurs when it is cold?
Shivering to increase body temperature
Which two body systems work together to regulate homeostasis?
Nervous System/ Endoctorine System
Why are feedback mechanisms important for homeostasis?
They help return the system to normal conditions
Why can bread rising be considered a form of positive feedback?
increased yeast activity leads to more gas production, which further increases rising until baking stops the process
How does sweating demonstrate negative feedback?
It lowers body temperature back to normal
What can happen if homeostasis is not maintained?
Disease/Illness/ Death
