Unspayed female dogs go into heat about once every eight months and it lasts for as long as three weeks each time. And they don't go into menopause. They regularly go into heat for their entire lives--unless they're spayed.
Dogs do not have periods. When a bitch goes into heat her teats may become enlarged.

Bees ( honey bees) become inactive at 45 degrees. death comes after they cannot convert their honey to heat their bodies. They create heat by shivering their flight muscles.
The heat in the asthenosphere primarily comes from the heat generated by the decay of radioactive isotopes in the mantle and the residual heat from Earth's formation. This heat causes the material in the asthenosphere to become less dense and rise, generating convection currents.
The same as dogs, the female comes on heat once a year and acts the same way a dog does to attract a mate.
In space there is no heat. Only when a satellite enters the atmosphere is there heat because of the friction and it begins to burn. Spacecraft have tiles on them to shield from the heat. Most satellites burn up in the atmosphere once they are done or become "space junk."
The warmth that you feel when rubbing your hands comes from the friction generated between your hands. When you rub your hands together, the energy from the motion is converted into heat, warming up your hands.
It depends on whether the kid is alive and suckling the doe and when she next comes on heat. She could become pregnant technically within 21 days but usually they do not as she is more interested in the kid than the buck and farmers do not want their does to get pregnant more than once a year as it puts a large nutritional strain on the doe.
Convection. Most of the heat is transferred from hot air heating the ground/water, or vise versa. The heat originally comes to earth from radiation from the sun, but once here, convection is how it is moved around.
Sedimentary rocks can be eroded into sediments and form sedimentary rocks again, they can melt and become igneous rocks, and they can undergo extreme heat and pressure and become metamorphic rocks.
Once the truck is shut off it was already "warmed-up." Once it is warmed-up all the heat in the big surface area has to be let go. This is where the fan comes in;the fan lets go of the extra heat buildup inside.
Because of the heat comes from the sun. So that the subtances become heat. Movement of ATOMS,
