The formula for calculating the index of dissimilarity is as follows: index of dissimilarity= 1/2 ∑_(i=1)^N▒|x_i/X- y_i/Y| Here‚ “x_i” represents the number of individuals of race “x” from tract “i”; likewise‚ “y_i” represents the number of individuals of race “y” from same tract “i.” The total populations of races “x” and “y” in the city are denoted by “X” and “Y‚” respectively.

Excretory system DEFINITION The excretory system is a passive biological system that removes excess‚ unnecessary materials from an organism‚ so as to help maintain homeostasis within the organism and prevent damage to the body. It is responsible for the elimination of the waste products of metabolism as well as other liquid and gaseous wastes‚ as urine and as a component of sweat and exhalation.

Discussion: The goal of surgical management for perianal fistula is to effectively eradicate current and recurrent septic foci‚ associated epithelialized tracts and preserve continence. No single technique achieves these aims for all types of anal fistulas. It is often necessary to balance the degree of sphincter division and continence disturbance. An ideal procedure for treating a fistula-in-ano should be minimally invasive with minimal failure rates and morbidity. 12 Based on the data available

Zachary’s Story A. An ulcer starts by eroding the mucosa of the G.I. tract wall. What functions of digestion and/or reabsorption might be lost if this layer is no longer functional? What functions will be compromised if the ulcer eats through the sub mucosa and then the muscularis? a. Absorption would not happen correctly some of the ingested and secreted may seep out of the lumen. This also could create a pathway of entry for pathogens if the ulcer ate through to the muscularis mucosa. You
