Question

Positive feedback loops Consider two variables: A and B. A positive feedback loop arises when A increases B, and B increases A. A. True B. False Consider the following scenario: The thermostat in Lucia's house regulates the temperature to 75 degrees Fahrenheit. As the temperature in the house rises above 75 degrees, the thermostat turns on the air conditioner which cools the house back down towards 75 degrees. This interaction between the temperature and use of the air conditioner______an example of a positive feedback loop.

Answer 1

1. A positive feedback loop arises when A increases B, and B increases A.

A. True

2. The thermostat in Lucia's house regulates the temperature to 75 degrees Fahrenheit. As the temperature in the house rises above 75 degrees, the thermostat turns on the air conditioner which cools the house back down towards 75 degrees. This interaction between the temperature and use of the air conditioner___is not___an example of a positive feedback loop.

Step-by-step explanation:

The best way to explain a positive feedback loop is to study what usually occurs in nature when the product of a reaction leads to an increase in that reaction. For example, in labor and childbirth, a body system in homeostasis or equilibrium is moved away from that equilibrium. It is negative feedback loops that can return a system to equilibrium as described in the example of the thermostat and the air conditioner above.
