What is wood thermal conductivity (w/(m•k)

Thermal properties of wood. ... For example, the thermal conductivity of pine in the direction of the grain is 0.22 W/moC, and perpendicular to the grain 0.14 W/moC. Increasing the moisture in the wood also increases its thermal conductivity. As the temperature of wood decreases, its strength usually increases

i'd say that the moon rock is about 2.2 billion years old.

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.
