Basophils of the blood help to get defensive leukocytes to the site quickly by releasing an anticoagulant called ___heparin and a vasodilator called histamine

Explanation:

Basophils are a type of white blood cell containing specific granules that release histamine (vasodilator) and heparin (a substance with anticoagulant action) and azurophilic granules that contain lysosomes. They are important in allergic and anaphylactic processes.

gold i'm pretty sure i might be wrong

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
