Answer:
Evolution occurs about 6 million years ago.
Explanation:
The mammoth evolved from the common ancestor because evolution occurs about 6 million years ago. The modern elephants and woolly mammoths share a common ancestor and they are split into two separate species about 6 million years ago due to change in genetics as well as environment that leads to the evolution in the elephants.
Komodo dragons can reproduce both sexually and asexually depending on the environment. They can do this because of Parthenogenesis (Parthenogenesis is a natural form of asexual reproduction in which growth and development of embryos occur without fertilization. In animals, parthenogenesis means the development of an embryo from an unfertilized egg cell.)
The patient can be subjected to intraoperative cholangiography wherein a stent in the bile duct will be placed and a radiopaque dye will be injected. X-rays will be taken. This is to locate the level of obstruction and to confirm if there is a common bile duct obstruction. In extracting stones, the surgeon can prefer doing an endoscopic retrograde cholangiopancreatography or ERCP and perform basket extraction of the common bile duct stone; or to surgically remove the sphincter of Oddi to allow easy passage of the stones.
Hypocalcemia or low calcium level is most usually the cause of electrolyte disturbance after a thyroid surgery.
