Question 1: The right answer is False.
The hangover occurs for several reasons. The first is that alcohol causes strong dehydration (normal, it is very diuretic). It is this dehydration that causes headaches, dry mouth, and difficulty concentrating in the aftermath of, particularly wet evenings. In addition, alcohol is high in sugar: as it encourages the body to produce insulin, it lowers our blood sugar ... which also causes intolerable headaches that are difficult to get rid of. get rid of.
But those who are least prone to a hangover are especially those who are not very sensitive to the effects of acetaldehyde, the toxic substance produced when alcohol is metabolized by the liver. But if their metabolism does not feel as openly the effects of alcohol, it does not mean that these individuals are immune to its effects in the long term.
Question 2: the right answer is the retina.
The retina is composed of two layers, a pigmented outer leaflet, and an internal neuro-sensory leaflet.
The internal leaflet (neurosensory retina) is composed of layers, nerve circuits, and photoreceptors in conical form or in rods.
