The crossword solution for the term 'CHECK FOR ODORS' is SNIFF. Sniffing is a common way to detect odors, as it involves inhaling air through the nose and detecting the molecules that make up the odor. This is done by the olfactory system, which is made up of specialized cells in the nose that detect odors and send signals to the brain. Sniffing is an important part of many jobs, such as food safety inspectors, who must check for odors that could indicate spoilage or contamination.
