Norah observes some velvet-green growth on a tree trunk. when she picks up one of these plants, she notices that the plant has a flattened body and is attached to the tree trunk by means of root-like structures. what is the plant?

i am going to guess that it is co2.

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.

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.
