people are warm blooded. however, people could not survive extreme cold or heat. so people often adapt the environment to meet their needs. for example, in very cold weather people heat their homes and wear warm clothing. in very warm weather, people wear lighter clothing.

1. why should you wear several layers of clothing in the winter?
2. how do people control the indoor environment during warm weather?

Explanation:

1. As per the text, cold - blooded animals' body temperature changes with the surroundings.
2. The text states that warm - blooded animals' body temperature stays the same when surroundings change.
3. The text clearly mentions fish and frogs as cold - blooded.
4. The text says birds are warm - blooded.
5. The text includes turtles in cold - blooded animals.
6. People are warm - blooded. In winter (cold), wearing layers helps retain body heat (as per the example of adapting environment in the text).
7. In warm weather, as per the text example, people wear lighter clothing. For indoor, they might use cooling methods like air - conditioners (a common way to adapt the environment as people adapt environment to meet needs).

Answer:

1. changes
2. stays the same
3. coldblooded
4. warmblooded
5. coldblooded
6. Because people are warmblooded and wearing several layers of clothing helps to keep the body warm in cold winter weather (by retaining body heat).
7. People may use air - conditioners (or similar cooling devices) to control the indoor environment during warm weather (to make it cooler as they adapt the environment to meet their needs).
