A:In cerebral achromatopsia, a person perceives apparent colors even though the eyes cannot distinguish them. Most sources consider this to be true color blindness, even though the individuals with the condition insist that they see colors. It is a form of visual agnosia. B:Would a pathologist examining a deceased person's eye tissue be able to determine that they had a defect of color vision? Answer: ix
A:In cerebral achromatopsia, a person sees only in black and white even though the eyes are capable of distinguishing colors. Some sources do not consider these to be true color blindness, because the failure is of perception, not of vision. They are forms of visual agnosia. B:Would a person with cerebral achromatopsia be likely to say that the sky was a particularly lovely shade of blue today? Answer: tions

A:At standard conditions for temperature and pressure it is a liquid; the only other element that is liquid under these conditions is mercury. At high temperatures, organobromine compounds readily dissociate to yield free bromine atoms, a process that stops free radical chemical chain reactions. This effect makes organobromine compounds useful as fire retardants, and more than half the bromine produced worldwide each year is put to this purpose. The same property causes ultraviolet sunlight to dissociate volatile organobromine compounds in the atmosphere to yield free bromine atoms, causing ozone depletion. As a result, many organobromine compounds—such as the pesticide methyl bromide—are no longer used. Bromine compounds are still used in well drilling fluids, in photographic film, and as an intermediate in the manufacture of organic chemicals. B:Is there any ban for organobromine compounds? Answer: ix
