lol sounds like your doing the same questions as me
no. it keeps your body cool.
Your blood. :)
protects the body and keeps it warm
feather
keeps you warm (fat)
No because their body fat keeps them warm.
Because it traps the heat that comes from your body from escaping, so you have more heat so it keeps you warm.
your skin is not what keeps you warm its your body temperature
keeps us warm by maintaining body temperature.
It depends, in general I would say body heat.
Seals have blubber, a layer of fat, which keeps them warm.
A blanket keeps you warm by trapping and retaining your body heat, creating a layer of insulation that helps to maintain your body temperature.
