Pigs, which have the largest litter size of all even-toed ungulates, have two rows of teats lined from the armpit to the groin area. In most cases, however, even-toed ungulates have only one or two pairs of teats. In some species, these form an udder in the groin region.
What is a roundabout? A modern roundabout is a circular intersection where drivers travel counterclockwise around a center island. There are no traffic signals or stop signs in a modern roundabout. Drivers yield at entry to traffic in the roundabout, then enter the intersection and exit at their desired street. Studies by the Federal Highway Administration have found that roundabouts can increase traffic capacity by 30 percent to 50 percent compared to traditional intersections.
Do not enter unless a safe gap is present. If there is no traffic in the roundabout, you may enter the roundabout without yielding. 1  Crosswalks are placed one or two car-lengths before the roundabout itself. 2  Yield to any pedestrians who are in, or about to enter, the crosswalk.his will inform other drivers that you wish to exit the roundabout, easing confusion. 5. Yield only to pedestrians in the crosswalk or emergency vehicles when exiting a roundabout. Remember that drivers inside the roundabout have the right-of-way.
