Lets say the plant that formed nodules is Species A, and the one who didn't is Species B.
If the nitrogen is concentrated in one area but at a low concentration, then Species A may have formed nodules because it is closer to the concentrated nitrogen. Species B didn't because the nitrogen that is active is being taken by Species A.
The right answer is: <span>Kingdom Plantae
The term "plants" includes plant organisms, mostly terrestrial, consisting of an upper leafy stem and anchored (planted) in the soil.
Plantae kingdom contains only non-motile multicellular nucleated organisms.
Not all of the Animalia are non-motile (spermatozoids and some immune cells are mobile).
Protista Are unicellular organisms, not multicellular.</span>
The tricuspid valve has three cusps that are essential components of the valve. (Hence "tri-" in tricuspid. ) The semilunar valve is called semilunar because each semilunar valve has cusps in the shape of half moons. Hope this helps to contrast their structure!
answer: both aspects , sameness &variety are the result of biological evolution.
