This excess urea is then taken out of the body through the kidneys as a component of urine. Some bacteria have the ability to produce an enzyme urease as part of its metabolism to break down urea to ammonia and carbon dioxide.
An acute angle (acute meaning sharp) is an angle smaller than a right angle (it is less than 90 degrees). Related pages[change | change source] This short article about mathematics can be made longer. You can help Wikipedia by adding to it.
Note that an angle measuring exactly 90Â° is not an acute angle. Instead, it's a right angle. When you think of angles, you should think of them as part of the radius of a circle, which is 360Â° in total. An acute angle makes up less than one-quarter of that circle's radiusâagain, less than 90Â°.
