Nitrogen Fixation: Root and Bacteria Interactions. Nitrogen is an important macronutrient because it is part of nucleic acids and proteins. ... The most important source of BNF is the symbiotic interaction between soil bacteria and legume plants, including many crops important to humans.
Answer:
Phagocytosis
Explanation:
Both macrophages and neutrophils are phagocytes, this means that they engulf large cells (up to 0.5 µm) to kill them, or small particles in order to eliminate them from the circulation.
Phagocytes can be used to acquire nutrients but their most important task is to kill invading pathogens as a part of the immune system.
I hope you find this information useful and interesting! Good luck!
They are typically a carnivore. Scavenger's clean a dead body, decomposers eat the bones and the rest, and producers are always plants! Hope this helps!

Answer:
Average atomic mass = 21.38 amu.
Explanation:
Given data:
Mass of first isotope = 21 amu
Abundance of first isotope = 62%
Mass of second isotope = 22 amu
Abundance of second isotope = 38%
Average atomic mass = ?
Solution:
Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) / 100
Average atomic mass = (62×21)+(38×22) /100
Average atomic mass = 1302 +836 / 100
Average atomic mass = 2138 / 100
Average atomic mass = 21.38 amu.
