Cholangiocarcinoma is a rare cancer found in the tissue of the bile ducts, occurring in approximately two out of 100,000 people. Men and women are equally affected and most cases occur in people over age 65. The bile duct is a small tube that connects the liver and gallbladder to the small intestine. The ducts carry bile -- the liquid that helps break down fat in food during digestion â out of the liver. Tumors can develop anywhere on the bile ducts and are typically slow growing.
Soil formation is a long slow process. It's estimated that an inch of soil takes 500 to 1000 years to form. Soil is constantly being formed. It is also constantly being eroded.
Seeds that are sown shallow (up to 1 inch deep) should have 12 to 15 inches of soil to grow into. Seeds that are sown deeper than 1 inch should have a minimum of 18 inches of soil beneath them to grow into.If a seed is planted 3 inches into the soil, the total soil thickness should be at least 21 inches.The seed packaging will tell you how deep the seeds need to be sown to be successful.eeds that are sown shallow (up to 1 inch deep) should have 12 to 15 inches of soil to grow into.
