The first can occur as the result of a head injury, as this form of diabetes is caused by a hypothalamus or pituitary gland malfunction.

In times of scarcity when food and water supplies are limited, badgers may congregate in small groups to forage and hunt. Although earthworms comprise the majority of badgers' diets, they will eat other sources of food when worm supplies are limited. This is particularly true for badgers living close to urban centers that feast on food scrap remains from compost piles and g..

Why didn't mammals evolve with lungs and gills?

An organism develops a respiratory system based on its general habitat and biological requirements. Most mammals are based on land and are exposed to lots of air. Because of this, lungs are the best respiratory organs for mammals. Lungs are designed to extract oxygen from the air, which contains about 20 percent oxygen. Air is generally non-invasive, so organisms with lungs only need to process about 4 grams of air per breath.\nIn contrast, gills are built to receive water and extract oxygen from it. Seawater contains only 5 milliliters of oxygen per liter. This aquatic respiratory organ must ..
