Answer: It would cause influenza to spread rapidly if sick people came in contact with others at work.
The answer is nitrogen-fixing bacteria.
<span>Plants
are not able to directly use atmospheric nitrogen. It must be converted into different
form through a nitrogen cycle. In the process of nitrogen
fixation, nitrogen fixing bacteria converts atmospheric nitrogen into
ammonium. In the process of assimilation, plants incorporate
ammonium into proteins.</span>
Some legumes have a symbiotic relationship with bacteria that
live in their root system. These bacteria are called Rhizobia and have
the ability of nitrogen-fixation.
<span>The component of human milk that caries out the phagocytosis of bacteria is macrophages. Macrophages are also responsible for the production of complement proteins within human milk. Furthermore between 40% and 80% of breast milk is made up of macrophages, making it the most abundant cell type within human milk.</span>
