The brown adipose tissue (BAT) makes up about 5% of a newborn's body weight. Newborn babies cannot yet efficiently thermoregulate themselves because they are so young. The BAT helps a baby's body with non-shivering thermogenesis when the body falls below a certain temperature. It also serves as cushioning and protection for the body parts.
A newborn piglet will need to be kept warm since they can't generate their own heat. They will also need to be fed, given iron supplements, and vaccinated.
A source of heat.
Yes
just like any other terrestrial mammal... to prepare for reproduction
To create a fire you need a fuel source of some kind, oxygen (O2), and a heat source.
EM (or emergency heat) can be used if you have a problem with your other heat source such as a heat pump. In most cases, you will not need this but what it does is bi-passes the primary heat source and allows your secondary heat source (normally your furnace) to become the primary.
What needs a heat source to begin evaporating. Normally the sun is the heat source that evaporates water on the earths surface.
Fuel, oxygen, & an energy (heat) source.
yes they need some heat source during their first part of life.
A newborn mammal (such as a rat) does not need (and could not deal with) ANYTHING but its mother's milk. It is not until it is weaned that it will start taking solids.
To build a simple calorimeter, you will need a container to hold water, a thermometer to measure temperature changes, and a heat source to generate heat. Place the heat source under the container, measure the initial temperature of the water, and then record the temperature change as the heat source warms the water. This will help you calculate the amount of heat energy released by the heat source.
Yes they are - the need an external heat source to raise their temperature.
