Answer:
Bacteria that metabolize NO2- to give rise to NH4+ belongs to the family of denitrifying bacteria and nitrate ammonification bacteria such as pseudomonas.
Explanation:
Denitrifying bacteria uses NO2- as electron aceeptor thus converting the nitrite ion (NO2-) to ammonium ion(NH4+).
a) The above reaction is a reduction reaction because NO2- or nitrite ion accept electron to generated its reduced form known as ammonium(NH4+).
b) NO2- acting as electron acceptor in this reaction.
Answer:
Prokaryotic genomic DNA is attached to the plasma membrane in the form of a nucleoid, in contrast to eukaryotic DNA, which is located in a nucleus.
Explanation:
False
The genotype of an organism does not constitute its observable characteristics but rather its phenotype. A genotype of an organism is the genetic makeup of an organism while the phenotype is the visible characteristics.
It is, however, significant to understand that the phenotype of an organism is as a result of the interaction between the genotype and the environment.
Classification of organisms is done while considering many factors such as:Cell type- whether the organism is prokaryotic or eukaryoticCell structure- This includes both the presence and composition of the cell wallBody type- whether the organism is multicellular or unicellularMode of nutrition- the method through which the organism achieves its nutritional requirement, by consuming other organisms (heterotroph) or making its own food (autotroph)
