Disease Cycle
Disease Cycle:A disease cycle is the natural progression of a disease from its initial infection of a host to its eventual spread to other hosts. The cycle begins when a pathogen, such as a virus or bacteria, enters a new host. The pathogen then multiplies within the host, causing the host to become ill. The pathogen may then be transmitted to other hosts, where it begins the cycle anew.
Dissolved Oxygen (DO)
Dissolved Oxygen (DO):Dissolved oxygen is oxygen that is dissolved in water. It is an important parameter in water quality monitoring because it is necessary for aquatic life. Dissolved oxygen levels can be affected by many factors, including temperature, salinity, and pollution.
Dissolved Solids
Dissolved Solids:Dissolved solids are small particles that are dissolved in water. They can come from a variety of sources, including sewage, runoff from agriculture, and industrial wastewater. Dissolved solids can make water unsuitable for drinking and can also affect aquatic life.
Dormancy
Dormancy: A state of reduced physiological activity in an organism.Dormancy is a strategy that helps plants and animals survive periods of adverse conditions, such as cold weather or drought. By dormancy, an organism can reduce its metabolic rate, conserve energy and water, and avoid damage from the environment.Dormancy is characterized by a number of changes in an organism’s physiology, including a decrease in heart rate, respiration, and body temperature. These changes allow the organism to enter a state of reduced activity or even complete stasis.
