Do trees have body heat?

le evapotranspiration xdd

so, by your judgment, is hair dead?

Well sort of, I was more leaning to surface area as a factor. Im also pretty sure the areas strawberry trees grow in have similiar temperatures in both the ground water (14 degrees) and air. Southern California is an exception to this I guess.

Hair is dead, by definition. The only part that is alive is the follicle.

yes

so, is extracellular matrix dead? is dentine dead?

>dentine
No
ECM
Yes, in the same way a protein is dead. An organism is a living thing composed of a lot of dead things.

protein is NOT dead
protein is the source or the carrier of life functions

dentine contains no living cells, so it's as dead as hair

Oops you are right, I was thinking of the pulp chamber.
Yes it is, a vial full of alcohol dehydrogenase is not alive. Hell people have arguments whether or not viruses are alive and they are protein coats with DNA inside of them which is far more than any lone protein.

By no definition of life I am aware of a single protein is alive.
