Immunological memory refers to the ability of the immune system to react previous antigen infections.
<h3>What are primary and secondary immune responses?</h3>
The primary immune response refers to the initial interaction between the immune system with pathogenic microorganisms (e.g., bacteria).
The secondary immune responses refer to the second contact with the same pathogenic organism, which enables to the organism create specific antibodies against this pathogen through a process called immunological memory.
Active Immunity is a term used to refer to a type of acquired immunity caused by previous exposure to a pathogenic microorganism and/or vaccine inoculation.
Immunological memory leads to a faster and better response of the immune system against pathogen reinfection.
In conclusion, immunological memory refers to the ability of the immune system to react previous antigen infections.

Answer:
True
Explanation:
Nitrogen is a fundamental component of both inorganic and organic compounds, where it is the main constituent of biomolecules such as nucleic acids (DNA, RNA) and proteins. The nitrogen cycle refers to the biogeochemical processes by which nitrogen circulates between the components of an ecosystem, i.e., between organisms (like plants and decomposers), and non-living things (i.e., soil, water, air). This cycle consists of several processes which include, among others, nitrogen fixation (i.e., the process by which nitrogen in the atmosphere is converted into ammonia), nitrification (i.e., the oxidation of ammonia is oxidized into nitrite and subsequent transformation of nitrites into nitrates), denitrification (where nitrate is reduced), anaerobic ammonia oxidation and putrefaction.
