They are primary subtractive colours, because each of them can be formed by subtracting a primary additive colour from the white light (blue, green, and red).
The thing about fiber evidence is that it disappears quickly so time is limited on how long to work with the fiber evidence
<span>Natural nitrogen fixation; An important part of the natural nitrogen cycle were nitrogen gas (N2) in the atmosphere is converted into ammonia (NH3) in in the ground. Some bacteria (diazotrophs), both free living in the soil and in symbiosis with root nodules of some plants, use enzymes (nitrogenazes) to convert the nitrogen into a form that can be used by living organisms.Hope this helps :/
