Homeostasis is
The process by which organisms maintain a relatively stable internal environment
The process by which organisms change their internal environment
The process by which organisms adapt to their external environment
The process by which organisms evolve over time
A Negative Feedback Loop is...
A process that reinforces a system's output
A process that counteracts a system's output
A process that has no effect on a system's output
A process that amplifies a system's output
A Positive Feedback loop is...
A system where the output enhances the original stimulus
A system where the output suppresses the original stimulus
A system where the output has no effect on the original stimulus
A system where the output reverses the original stimulus
During Homeostasis...
The sensor sends a message to the effector
The effector sends a message to the control center
The sensor sends a message to the control center
The control center sends a message to the sensor
Negative feedback loops
Have negative effects on the body
Hurt the body
Help the body
Correct an imbalance in the opposite direction
Positive feedback loops
Are good things
Always heal the body
Increase a change in the body
Are bad
In homeostasis the control center
Sends a message to the effector
Sends a message to the sensor
Causes a change to the environment
Always causes a positive feedback loop
This image shows what kind of feedback loop?
Positive
Negative
Hypotonic
Enzymatic

From B to A
This graph demonstrates a
Positive feedback loop
Negative Feedback Loop

Phospholipid
What is the point of a feedback loop?
To provide the body with more energy
To provide the body with more food
To make sure the conditions in the body are always changing
To make sure the conditions in the body remain stable
Isotonic solutions...
Increase cell volume
Decrease cell volume
Do not change cell volume
Cause cells to burst
