Naturally occurring reactive oxygen molecules and ionizing radiation are prevalent sources of such damage11.
Basalt is naturally highly reactive with CO2; when the two meet, they undergo a series of exchanges that culminate with the carbon precipitating out as a solid whitish substance, similar to limestone.
We can hypothesize that monkeys are naturally highly reactive since vigilance is crucial for their survival, whereas it is probably not as disturbing for girls to hear another girl coming from behind due to the fact that it is a common event with far less drastic consequences.
Lightning accounts for some naturally occurring reactive nitrogen worldwide each year, lightning fixes an estimated 3 10 teragrams (Tg), the usual measurement unit for discussing the global nitrogen cycle.
Most naturally occurring reactive nitrogen comes from nitrogen fixation by bacteria, including cyanobacteria and specialized bacteria such as those in the genus Rhizobium, which most often live symbiotically in plants such as peas, beans, and alfalfa.
As a highly reactive, naturally occurring endogenous compound, with efficient metabolic mechanisms in place to protect against increases in concentrations in any tissues, there is a detailed understanding of formaldehyde-induced toxicity.
Degassing in organic C based PRB systems due to the production of gases (primarily CO2 and CH4) is investigated using the depletion of naturally occurring non-reactive gases Ar and N2, to identify, confirm, and quantify chemical and physical processes.
Naturally occurring, auto-reactive B cells have been found to undergo several distinct fates in vivo: they can be physically eliminated, functionally inactivated, or they can persist unchanged or become activated (Goodnow 1992).
The presence of naturally occurring cross-reactive influenza virus antibodies in a significant percentage of children has important implications for the development of a universal influenza vaccine.
To the best of our knowledge, the presence of naturally occurring cross-reactive antibodies against seasonal infections following significant antigenic drift has not been reported.
