Gregor Mendel's research consisted of using parent pea plants that were pure breeds. What genotype(s) would be considered pure breeds? (use the letter "B" and/or "b" in your genotype) *

your body is trying to warm itself up. or more precisely, sensors in your skin send messages to your brain to generate heat to your body.

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.
