What do both glycolysis and fermentation have in common? A. the can occur in the absence of oxygen
B. they produce either lactic acid or ethyl alcohol
C. they involve a serious of reactions that progress in a circular fashion
D. they combine hydrogen with oxygen to produce water

Ambas se realizan en ausencia de oxigeno

Respuesta A

Explanation:

La fermentación láctica transforma el piruvato en lactato

Durante la glucolisis una molecula de glucosa se convierte en 2 moleculas de piruvato y se obtienen 2 moleculas de ATP y 2 de NADH netas.

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
