Ummmm... from my book females have wider area 90 degrees or something like that, while males have slimmer area like 60 degrees or something. Obviously not everyone has that type of area surface but I think ?typically? They are around those degrees.
Well, hope this helps you even though it is all weird and stuff
Answer:
Are these true or false questions or-?
Explanation:
I can answer in comments if they are..
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.
