Question

1. homeostasis is the state of steady internal conditions maintained by living systems. explain the relationship between the pancreas and homeostasis. 8. explain how the thermostat in your house uses a negative - feedback system to maintain your homes temperature.

Explanation:

1. The pancreas plays a crucial role in maintaining blood - glucose homeostasis. It secretes insulin when blood glucose is high, which prompts cells to take in glucose, and glucagon when blood glucose is low, which stimulates the liver to release glucose.
2. A thermostat in a house is set to a desired temperature. When the actual temperature rises above this set - point, the thermostat signals the air - conditioning to turn on and cool the house. When the temperature drops below the set - point, it signals the heating system to turn on. This is a negative feedback system as the response counteracts the initial change in temperature.

Answer:

1. The pancreas secretes insulin and glucagon to regulate blood - glucose levels for homeostasis.
2. A thermostat senses temperature changes, signals heating or cooling systems to maintain the set temperature via negative feedback.
