Which evolutionary effect results in reduced genetic variation in a community?

The founder effect.

Explanation:

The founder effect does result in a reduction in the genetic variation in a community. When only a handful of organisms reach a new area with suitable resources, such as an island, many of the gene pool in the original community is lost and this increases the chances for evolution of something new as time and adaptation to new resources and conditions exert their effect.

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.

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.
