Plutonium is much rarer in nature than uranium and is more commonly used for bombs rather than as reactor fuel. Like uranium, it comes in various isotope forms, with plutonium 239 the most commonly used. It is mixed with the much more unstable plutonium 240 to generate power.
It's my understanding that a horse's knees close around age 2- 2 1/2. My gelding JUST turned 3. A couple days ago in fact. Will a horse's knees almost certainly be closed by that age?
An adult horse at rest will have a pulse rate ranging from 30 to 40 beats per minute. Foals will have a pulse rate ranging from 70 to 120, yearlings from 45 to 60 and two-year-olds from 40 to 50. If you are using a stethoscope, place it on the horse s girth area just behind the left elbow.
