Answer:
Dissimilatory- oxygen absent
Assimilatory- high concentration of nitrite
Explanation:
In assimilatory nitrate reduction, ammonium is produced and subsequently incorporated into biomass to build up e.g., proteins and nucleic acids. Dissimilatory nitrate reduction is a process for energy conservation, in which nitrate is used as an electron acceptor in the (near) absence of oxygen . Dissimilatory nitrate reduction and nitrate storage in particular are physiological life traits that provide microbes with environmental flexibility (i.e., metabolic activity under both oxic and anoxic conditions) and resource independence (i.e., anaerobic metabolism without immediate nitrate supply), respectively. Such life traits are especially important in environments that are temporarily anoxic and/or nitrate-free and they may have developed as a “life strategy” in both prokaryotes and eukaryotes
Bacteria are classified into 5 groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes). They can exist as single cells, in pairs, chains or clusters.
Answer:
Option A. are mostly non-metals.
Explanation:
Oxidising agents are mostly non-metals because non metals gains electron from the metal during chemical bond and we know that oxidising agent is electron accepter not donar. For example, Sodium is a metal react with chlorine which is a non-metal so the sodium losses electron and this electron is gain by chlorine atom forming sodium chloride. In this example chlorine is a non-metal which gains electron.
