What are used to help conserve heat in houses?
Loft insulation and double glazing.
What happens to blood vessels in the skin when the body temperature gets too high?
When body temperature drops below normal, dermal vessels are likely to constrict to maintain core body temperature, limiting heat loss through the skin. In contrast, when body temperature is elevated, the vessels in the dermis are likely to dilate to help the body release excess heat.
How do ovens conserve heat?
Ovens retain heat by utilizing insulation. The insulative coverings help prevent thermal conduction through the walls of the oven.
Do arctic foxes keep warm or cool?
They have smaller ears to conserve heat. Foxes from warmer areas have larger ears to help dissipate heat.
Do polar bears have large hairy ears?
No, they have smaller, but hairy, ears to help conserve heat.
Can you conserve heat released in a refrigerator?
As refrigerators give off heat from the back, the only real way to conserve the heat from it is to use it in a room that is already cold. Thus using the heat from the heat exchange on the back to add to any heat source in the room. This will not act as a heater for the room but may help to maintain the temperature very slightly when the heating is turned off.
Do ectothemic animals control their body temperature?
Sometimes. Very small mammals will have small ears to help conserve their body heat. The exceptions to this are rabbits and hares. Also marine mammals (large and small) have lost their external ears for much the same reason. The exception to this is sea-lions who still have external ears. Large terrestial mammals have large ears as they have little need to conserve body temperature. The elephant has very large ears which they flap for the purpose of radiating away excess body heat.
What is main reason for assuming the HELP position when you are stranded in the water?
In cold waters, assume the HELP position (Heat Escape Lessening Position). This is where you roll up into a ball with your chest against your thighs, while gripping your ankles. This will allow your body to retain heat longer, and could save your life if it gives more time for a ship to come by.

How does the body conserve heat?
It will try to generate heat by making the muscles move rapidly through shivering. Also your hair will raise hoping to trap heat between the body and the hair. But we have very thin body hair and that doesn't help but we see the effects of the tiny muscles pulling on the hairs to make them erect. This causes the skin to be pushed into a small hill. Something we call "goose bumps". Otherwise we have to use our brains to find a warm place.
