Still needs a valid answer. What's the purpose functionally of the 2 valves being differently shaped?
I was proposed the same question by a student today, and the only answer I can come up with, besides because our common ancestors have it that way is there is a limitation of room in left ventricle. However what we think causes it is the fusion of the valves tissue from 3 cusps into 2 in human development.

Is there any way to save an evergreen tree if two-thirds of the tree has no needles?
As a master gardener, I have asked myself this same question, as you may or may not know if you remove two thirds of a trees life that tree is going to die, the sad part is I have many everygreens that I have in the same condition, and have not put forth the effort in saving, it is on the top of my list to do. First thing you need to ask yourself does this tree pose any threat to any building or people, how tall is your tree it takes time to save a tree, if your tree is less than 20 feet tall, open the ground around the trunk, you want to open the ground as wide as the tree is wide,put some mulch around and below the ball of the tree, once you have done this the next step is to feed the tree, evergreen miracid mix a 5 gallon bucket and feed it every 2 weeks you can just spill it out or you can put a small valve in the bottom of the bucket and let it drain out. your tree should after about 2 months begin looking a little better that will be 4 feedings, If the tree is larger than 20 feet you should use 2 five gallon buckets. This is a very slow process.

The heart and the blood vessels are separate organs that form the?
The upper part of the heart is made up of the other two chambers of the heart, called the right and left atria(pronounced: ay-tree-uh). The right and left atria receive the blood entering the heart. A wall called the interatrial(pronounced: in-tur-ay-tree-ul) septum divides the atria, and they're separated from the ventricles by the atrioventricular (pronounced: ay-tree-oh-ven-trik-yoo-lur) valve. The tricuspid valve separates the right atrium from the right ventricle, and the mitral (pronounced: my-trul) valve separates the left atrium and the left ventricle.Two other heart valves separate the ventricles and the large blood vessels that carry blood leaving the heart. These valves are called the pulmonic valve, which separates the right ventricle from the pulmonary artery leading to the lungs, and the aortic valve, which separates the left ventricle from the aorta, the body's largest blood vessel.

What is the difference between API 6A and API 6D valves?
It's quite easy. API 6A speaks about wellhead and x-mas tree equipment, API 6D speaks about pipeline valves. If you are phisically looking to one valve, you can also understand if it belows to 6A or 6D giving a look to the valve label. On the label you can read the class of the valve. If the class is 2000 or 3000 or 5000 or 10000 or 15000 or 20000 the valve is 6A. If the class is 125 or 150 or 300 or 400 or 600 or 900 or 1500 or 2500 the valve probably is a 6D ("probably" because the same classes of API 6D are used also by other API standards, like 594, 600, 608, ecc ecc).
