The occurrence of snow in the Seattle Tacoma area is extremely variable and usually melts before accumulating to measurable depths. There are winters on record with only a trace of snow but at the other extreme, over 21 inches has fallen in a 24 hour period.
The rabbit's sense of smell is far more developed than that of the human. Moveable folds inside the rabbit's nose assist in the detection of scent. The sense of smell in a rabbit is present at birth, allowing a newborn to find his mother's teat. Rabbits shift their noses up and down when trying to identify a scent; this is called nose blinking..
The human sense of smell. Although the human sense of smell is feeble compared to that of many animals, it is still very acute. We can recognise thousands of different smells, and we are able to detect odours even in infinitesimal quantities. Our smelling function is carried out by two small odour-detecting patches â made up of about five or six million yellowish cells â high up in the nasal passages. For comparison, a rabbit has 100 million of these olfactory receptors, and a dog 220 million. Humans are nonetheless capable of detecting certain substances in dilutions of less than one part in several billion parts of air.
