Directional selection is a type of natural selection that occurs when members of a population of a species with a particular extreme phenotype is selected or favored against the other phenotypes when natural forces act on the population of a species. Individuals having the particular traits that are favored survive and become more common that others with traits that are less favored.

Directional selection may likely result in the species of butterflies in which darkly collared butterflies are not preyed upon, ensuring their survival, while the other butterflies with other colors will be phased out with time.

What is pancreatitis and what is the basic mechanism that underlies the condition?
svp [43]
Pancreatitis is an inflammation of the pancreas that may be caused by years of heavy consumption of alcohol of gall stones. The pancreas plays major important roles such as secreting digestive juices into the small intestines, which help to digest fats, proteins, and the carbohydrates in food. It also release hormones insulin and glucagon that regulate the blood sugar. Pancreatitis is characterized by a pancreas being inflamed, therefore when this happens the body's normal complex coordination is disrupted and the enzymes in the pancreas are prematurely activated before they exit the organ, which results in these enzymes digesting the pancreatic tissue.
