The definition of high blood pressure -- anything above 140/90 -- remains the same under the new guidelines, James said. Lifestyle changes should be used to treat people who have high blood pressure readings that fall below the level where medicine is needed, he explained.
No. Mammals are divided into three infraclasses: monotremes, marsupials, and placental mammals. A giraffe is a placental mammal. This means that the baby is born live, and that it is born developed enough that it will not have to immediately crawl onto the mother's nipple and attach itself. In fact, baby giraffes can walk seconds after being born.
Marsupial Mammals. Marsupials are the group of mammals commonly thought of as pouched mammals (like the wallaby and kangaroo at left). They give live birth, but they do not have long gestation times like placental mammals.ike other mammals, the marsupials are covered with hair. Mothers nurse their young  a young kangaroo may nurse even when it has grown almost to the mother's size. The only naturally occurring marsupial in the United States is the opossum, Didelphis virginiana.
