Alcohol dehydrogenase is involved in the metabolism of alcohol. a cytoplasmic version of the enzyme catalyses the conversion of alcohol to acetaldehyde and a mitochondrial version catalyses the conversion of acetaldehyde to acetate, see reactions below. some people react to the consumption of alcohol with the appearance of a facial flush. in less than 100 words total i) name the biochemical basis for this physiological reaction and ii) explain in the language of this unit how the enzymatic properties of alcohol dehydrogenase relate to this physiological reaction.

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant. 

Deposition is the transition of matter going from gas to solid without passing through the liquid phase.a.) gas—-> solid
