Answer:
b) contact transmission.
Explanation:
Contact transmission of pathogens occurs directly or indirectly between the source of the pathogens and the host organisms. During contact transmission by droplet spread, the pathogen is carried on smaller particles. These particles move through air for a very short distance, usually less than a meter. Therefore, droplet transmission of a pathogen requires that the source and host are present in close proximity.
Answer:
eukarya
Explanation:
so long as that stands for eukaryotic
fungi is eukaryotic
other 2 are multicellular, and therefore eukaryotic
if u don't like the first explanation, the second one is process of elimination
archaebacteria is a kingdom, so it can't be that, same with plantae.
fungi isn't a bacteria so it can't be that either
only option remaining is eukarya
Nitrogen fixation is the process by which nitrogen is taken from its relatively inert molecular form (N2) in the atmosphere and converted into nitrogen compounds useful for other chemical processes (such as, notably, ammonia, nitrate and nitrogen dioxide).
Nitrogen fixation is performed naturally by certain types of anaerobic bacteria. Legumes such as clover contain symbiotic bacteria of this type within nodules in their root systems, producing nitrogen compounds that help to fertilize the soil. See George Washington Carver.
Nitrogen can also be artificially fixed for use as fertilizer or in other industrial processes. The most popular method is by the Haber process. Artificial fertilizer production has achieved such scale that it is now the largest source of fixed nitrogen in the Earth's ecosystem.
