The Respiratory System

System’s development during the embryonic life The respiratory system begins to develop at the fourth week of gestation. It is necessary to point out here that the respiratory system consists of two main parts or regions. The upper respiratory tract, which is composed of the nose, nasal cavity and pharynx and the lower respiratory tract […]

Acid Rain Theme

Acid rain is rain that is more acidic than normal. Acid rain is a complicated problem. Primarily caused by air pollution, acid rain’s spread and damage involves weather, chemistry, soil, and the life cycles of plants and animals on the land and in lakes and streams. This form of air pollution is currently a subject […]

Acid Presipitation

Acid Rain is caused by pollution containing sulfur dioxide, nitrogen oxide, and ozone that is released into the air. These chemicals are absorbed into clouds and results in Acid Presipitation ( Acid Rain, Acid Snow, Acid Hail, Acid Sleet ). When the chemicals aren’t absorbed into the clouds, they can drift for miles and fall […]

Acid Rain Critical

Introduction Acid rain has become an environmental concern of global importance within the last decade. With the increasing environmental awareness of the “unhealthy” condition of our planet earth the concern about acid rain has not lessened. In brief, acid rain is rain with pH values of less than 5.6. When dealing with acid rain one […]
