1. If an organism has 2n = 2 chromosomes, draw how the cell will look a) in metaphase of mitosis b) in metaphase I c) in metaphase II d) in anaphase of mitosis e) in anaphase I f) in anaphase II

Mitosis is a cell division process where a cell divides to two identical daughter cells.

Explanation:

Mitosis is required for growth of an organism, repair or replacement of tissue and cells.  The different steps of mitosis are:

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.

i hope this

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.
