Homeostasis is the balancing, through regulation, of the internal body environment to maintain the stable conditions necessary for proper body functions. The shivering is a first response by Veronica's body to maintain body temperatures. However, when another homeostatic process begins such as the constriction of blood vessels, the body can maintain heat without shivering. Shivering is a high energy consumption process.
There is only one legitimate interpretation of the meaning of red shift data. The red shifts of quasars and connected galaxies can be different by billions of light-years. The discovery of quantized red shift observed in related galaxies has no relation to the Big Bang model.
If the air cools to its dew point temperature (in other words if it reaches saturation with respect to water vapor), condensation is forced and some of the water vapor in the air condenses into liquid water droplets.
