With the increased use of chloramines (e.g., NH2CI) as a residual disinfectant in water supply, ammonia concentrations in drinking water have increased. Nitrifying microorganisms use ammonia (NH4) as an electron donor (oxidized to NO) and oxygen (Oz) as an electron acceptor (reduced to H2O) in a process known as nitrification. The microorganisms use inorganic carbon (dissolved COz and HCO3) as their carbon sources. These microorganisms can be classified as ( )? A. photoautotroph B. chemoautotroph C. chemoheterotroph

Electronic Spreadsheet

Tabular listing has many advantages ranging from time management to efficient scheduling of tasks. Electronic spreadsheets allow the user to tabulate and analyze data, using its easy-to-use interface. An electronic spreadsheet is a staple application used among accountants, management staff, and IT professionals. It is used in various sectors worldwide for data management. An electronic spreadsheet is a system and computer software that could be used to do numerical computations automatically. Spreadsheet application programs are often organized as a table with rows and columns. Each row and column intersect to form a cell, which may be used to store data. These data can take the form of a written label, a number, or a formula that combines information from other cells.
