A slight majority, 53%, think teens should be at least 18 to get a license. The poll of 1,002 adults, conducted Dec. 17-19, 2004, has an error margin of +/-3 percentage points. Many states have begun to raise the age by imposing restrictions on 16-year-old drivers.
Do snakes really smell with their tongues? Snakes do use their tongues to smell! Snakes have nostrils, just like humans. But a snakeâs tongue is also very important. When a snake flicks its tongue in the air, it picks up tiny chemical particles. When the snake brings its tongue back into its mouth, the tongue fits into a special organ on the roof of the mouth. This special organ is called the vomeronasal system. The vomeronasal system takes those tiny chemical particles and tells the snake what they are.
Q: How do snakes breathe ? A: Snakes don't have a diaphram as we do so must use muscles along their sides to expand and contract their lungs. Most snakes have only one main, functional lung but it functions much as ours does to obtain oxygen. When a snake is feeding on a large prey item it can also push its trachea (windpipe) off to the side so it can still breathe with a mouth full of food.
