Unlike conduction and convection, heat transfer by thermal radiation does not necessarily need a material medium for the energy transfer. In the case of thermal radiation from a solid surface, the medium through which the radiation passes could be vacuum, gas, or liquid.
Answer:
Lamark suggested that organisms can acquire traits which benefit them without any genetic means. He suggested that a change was gradually introduced into organisms of a species during their lifetime and this change could then be seen in the offsprings.
This idea was wrong because an organisms characteristics cannot change in his lifetime.
The theory of Lamarck's inheritance can be disregarded by our knowledge about hereditary genetics.

Explanation:
a and b) Metformine inhibits the enzime glycerol-3-phosphate dehydrogenase. This enzime catalyzes the conversion of glycerol phosphate to dihidrocetone phosphate. This decreases the concentration of NAD on the cytosol, and the realation NADH/NAD increases in this comparment, and decreases on the mitochondria, which restricts the conversion of lactate to pyruvate, preventing the use of the substracts to the gluconeogenesis.
Answer:
In the boreal forest the ground thaws more and does not have a permafrost layer. This allows trees to take root. Compose an argument for categorizing mountains and polar regions as terrestrial biomes. Mountains and polar regions have these characteristics and provide land on which certain plants and animals can live.
