Scientists have determined that a type of marsupial called an opossum shares a common ancestor with wallabies that live in Australia. This is an amazing idea since the two continents are thousands of miles apart! What evidence best explains how these two animals from different parts of the world could possibly be related?

a. A thousand years ago the opossum developed the ability to swim which allowed it to leave Australia.

b. Both marsupials evolved from a different marsupial in Africa.

c. The marsupials evolved differently as they adapted to different continents that were once connected.

d. Before oceans formed, the animals were able to travel to separate continents.

the answer would be   10%

not always but somethings can be reproduced in a laboratory.

the right answer is

74300-26

47563 (which stands for cholecystectomy with cholangiography).

and also:

47600 for cholecystectomy

47605 with cholangiography

the gallbladder is an organ of the digestive system. contained in the abdominal cavity, it serves as a reservoir for the bile secreted by the liver, which empties it via the common bile duct into the duodenum (initial part of the small intestine). bile participates in digestion.

ablation of the gallbladder or cholecystectomy is indicated in case of gallbladder stones (symptomatic stones). the intervention prevents recurrences and complications.
