A hands-on microscopic course consisting of (1) an in-depth light and electron microscopic study of cells, tissues and organs; and (2) an intensive modular directed study of the microscopic composition and development of oral and facial structures. WebOrganic tests. Aquatic animals require dissolved oxygen (DO) in water to live. Aerobic bacteria can degrade organic matters using dissolved oxygen in water and BOD measures the amount of oxygen used up by bacteria for degrading organic matter. BOD is an indicator for the amount of organic materials in the wastewater effluent.
