Answer:
1. Homeostasis the internal regulation of the body. Keeps everything at the factory setting if you will.
2. Homeostasis is all about balance which is similar to a cell membrane in that the cell membrane will only allow certain particles to pass in order to balance salt and water concentration.
3. Endotherms experience homeostasis while ectotherms do not. Ectotherms are “cold blooded” and need to use external resources to warm and cool their body.
4. Negative feedback is a key part in homeostasis in that it helps signal the body to balance something out. Example: when it’s cold you shiver and when it’s hot you sweat. Both are examples of negative feedback.
