Answer:
homeostasis
Explanation:
Homeostasis has to do with processes that maintain the internal balance within an organism. It can succinctly be defined as the process of regulating an organism's internal environment. The process of homeostasis is very important in the maintenance of important indicators of balance in the body such as body temperature, body pH, etc.
Hence, when blood pH becomes overly acidic, respiration and kidney function change to bring the acidity back to its normal pH level of 7.4. This is a homeostatic response.
Answer:
The weather change as the earth warms because since,20th century due to human activities, particularly fossil-fuel burning which increases heat- trapping greenhouse gas levels in Earth's atmosphere.
The density of ice is less than water - that's why it floats on water. I think this property is unique in liquids.
If ice was equal or heavier density than water then the oceans would be solid except for near the surface, which would be very bad for aquatic life!!
