Organism Homeostasis Review

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

A feedback loop best fits which characteristic of life?

• Cells

• Organization

• Homeostasis

• Adaptation

In this body temperature feedback loop, predict what would happen if cooling mechanisms were NOT activated?

• The body would not warm up.

• The body would not cool down.

• Your body would get colder and colder.

• Your body would release lots of heat.

According to the feedback loop, what does high blood sugar promote?

• Insulin Release

• Glucagon Release

• Insulin Uptake

• Glycogen Uptake

What is the difference between what will happen if their is too much Glucose or too little Glucose? SELECT ALL THAT APPLY

• With too much Glucose, Insulin is released. With too little Glucose, Glucagon is released.

• With too much Glucose, the pancreas produces insulin. With too little Glucose, the pancreas produces glucagon.

• With too much Glucose, Glucagon is released. With too little Glucose, Insulin is released.

• There is no difference.

Failure to maintain homeostasis could result in:

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

Maintaining body temperature is an example of a:

• negative feedback loop
• positive feedback loop

Humans have ___ for body temperature, blood glucose concentrations, electrolyte concentrations, pH levels, tendon tension and variables.

• positive feedback mechanisms
• set points
• a wide internal range
• no regulation

The "cause" for something to happen is the

• response
• effect
• stimulus
• homeostasis

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

• response
• stimulus
