Nitrogen fixation,Denitrification and nitrification
The scientific method in which biological problems are solved is termed as biological method.It comprises the steps a biologist adopt in order to solve a biological problem,In solving a biological problem a biologist adopt the following steps 1) Recognition of biological problem. 2) Observation. 3) Hypothesis formulation. 4) Deduction. 5) Experimentation. 6) Summarization of result. 7) Reporting of result. 8) Formation of theory. 9) Biological Law
A Biological Technician assists biological and medical scientists, maintains laboratory equipment, takes calculations and makes evaluations, and sometimes observes organic substances, such as food, blood, or drugs.
The mango belongs to the biological family Anacardiaceae, but the almond belongs to the biological family Rosaceae.
Biological messengers are molecules thatÊtransmit information about cells to the receptor. They are also called neurotransmitters, first messengers, or second messengers.
Biological nitrogen fixation was discovered by the Dutch microbiologist Martinus Beijerinck.

Nitrogen fixation.
Bacteria combines with hydrogen to make ammonia, which is changed and turned into compounds such as nitrate or nitrogeNitrogen fixation is the natural process, either biological or abiotic, by which nitrogen (N2) in the atmosphere is converted into ammonia (NH3).

Nitrogen fixation is the conversion of atmospheric nitrogen, N2, into some biological form, such as ammonia, NH3, or nitrogen dioxide, NO2. In nature, this process is most often completed by nitrogen-fixing bacteria or diazotrophs. Nitrogen fixation is important because only fixed nitrogen can be used for basic biological substances such as proteins and nucleic acids.

The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms. This transformation can be carried out to both biological and non-biological processes. Important processes in the nitrogen cycle include fixation, mineralization, nitrification, anddenitrification.
