The shape of the leaf is for the survival of the tree, not people. People use the leaves of certain trees for crafts and medicine, but this was not the purpose or intent of the tree. A leaf will be broad if it need to get rid of heat and let out excess water. A leaf will be in the shape of a needle to keep in heat. Extremely cold areas or area that have abundant snow will tend to have more trees with needles.

Vern Originally Answered: what is the purpose of "diplomatic immunity"?
Diplomatic Immunity is granted to protect diplomats from foreign countries from being abused by governments and from being falsely charged by a host government for political reasons. Can you imagine any US diplomat feeling free to work in Venezuela, if he did not have diplomatic immunity? He could be arrested and imprisoned any time Chavez wanted to make a statement against the US. Unfortunately, diplomatic immunity is too often abused by diplomats who take it as license to disregard the laws of the host country. Foreign diplomats park whereever they choose, double park, get into accidents and then ignore lawsuits, etc. NYC alone is owed millions in unpaid parking and traffic tickets owed by foreign diplomats. Still, without immunity, the entire worlds diplomatic intercourse would break down. We would have chaos.

Diplomatic immunity is a concept of foreign affairs which originated with Genghis Khan. It is thought that affairs between & among nations need representation which enjoys a certain immunity from prosecution of petty matters while in the "host" nation. The vigilantism you propose by personally revoking a nation's diplomats' privileges suggests that you are better prepared to survive in a barbaric setting, perhaps one prior to the Mongolian domination centuries ago.

Leaves occur in nature and their shapes are determined by natural selection and evolution through thousands of years to make them more adaptable to the slowly changing environment. Humans use different kinds of leaves in various ways dependent upon each leaf's shape, chemical composition, strength, versatility, etc. It is not the shape of the leaf that relates it to the purpose, but rather it is the purpose that seeks which leaf should best be used (from among the millions around).

A leaf shape is crucial to the plants survival. Plants have broad leaves to absorb sunlight in order for photosynthesis. However, a great surface area leaf to a desert plant would be disadvantageous due to the risk of loosing precious water. Therefore, most cacti reduce its leaves to spines and photosynthesis occur in the green stem. As far as uses suited to its shape, that doesn't seem to be a correlation since evolution favors the traits that enables the plant to survive not its use to humans as medicine or craft.

Moise Originally Answered: what is the purpose of the antibody test while trying to determin Hypothyrodism?
There are a couple of tests for antibodies, one of them called TPO. This is the test that will often show if there is hypothyroidism. Also, it's important that the dr check for Free T3 and Free T4 as these can tell if something is going on. The free of both of these are the parts that are left over, meaning not used by the thyroid. The T4 converts to T3. To learn more about thyroid disorders, and the tests check out: http://www.thyroid.about.com The ANA (antinuclear antibody) is one of the ways that they can check for Lupus and other arthritic conditions but sometimes the Lupus can be missed so other tests like a newer test that is now out called the Sera Protein test do a better job of finding out if one has Lupus (I'm eventually hoping to have this test done myself). A primary care physician can run an ANA but most of the time it's done by rheumatologists. Yes, sometimes an autoimmune disorder of the thyroid such as hypothyroidism in particular Hashimoto's can start with a virus. I would recommend being evaluated by an endocrinologist as they will run all the tests in the thyroid panel.
