Negative & Positive Feedback Loop

If the environment gets cold, we will often shiver in order to:

• keep body temperature the same as the external temperature
• decrease body temperature
• increase body temperature
• regulate blood pressure

The "cause" for something to happen is the

• response
• effect
• stimulus
• homeostasis

The "effect" of a given stimulus is the...

• response
• stimulus
• cause
• result

The two types of feedback systems that help organisms maintain homeostasis are:

• positive and negative 
• receptor and effector
• static and dynamic
• minor and major

Maintaining body temperature is an example of a:

• negative feedback loop
• positive feedback loop

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

The process of childbirth is an example of:

• negative feedback loop
• positive feedback loop

What type of feedback loop is shown?

• negative

• neutral

• positive

Failure to maintain homeostasis could result in:

• lack of internal balance
• eventual death
• difficulty carrying on metabolism 
• all three

Negative Feedback Loops:

• amplify processes
• prevent small changes from getting larger
• are initiated during childbirth
• are found only in plants
