NemiM [27]

The property rights approach to environmental issues often becomes highly relevant in cases involving endangered species.

The approach based on property rights postulates that if exclusive property rights are correctly established, the public good of maintaining high environmental quality may be converted into a private good, and the best possible distribution of environmental resources will be accomplished.

The protection of people's property rights is an efficient method for preserving and rehabilitating endangered animals. It is more likely that recovery will occur if these animals are owned by someone who will benefit in some way from their growth. But if endangered species are nothing more than a burden, any kind of financial incentive to preserve them is met with fierce opposition.

A person had bread and butter for his breakfast. Trace the changes in the main components of these during its passage through th
Papessa [141]

When the bread and butter is in mouth, mechanical digestion starts. The size of the food gets reduced and it mixes with saliva for easy swallowing. The salivary amylase in saliva begins the digestion of starch in the bread. This is the start of chemical digestion. When the undigested bread and butter reached the stomach, lower esophageal sphincter relaxes and allow the chewed food to enter. The gastric secretions containing HCl, acts on the undigested food to produce chime. HCl kill the microorganism on the food and also denatures the protein and later attacked by digestive enzyme pepsin. Pepsin breakdown protein in the bread, butter . Later on gastric lipase begins to digest fat present in butter. Digestion of the starch in bread does not occur in the stomach because the salivary amylase that began chemical digestion in mouth became inactive in the presence of HCl. Further the chime enters the small intestine where bile secreted by the gall bladder emulsifies the fat and break into small globule which helps in fat absorption.
