Differences in traits such as hair texture are determined by differences in ? A) The location of sugar groups in DNA B)the sequence of nucleotides in DNA C) The number of nitrogenous bases un DNA D)The molecules attached to the phosphate in DNA

A

Explanation:

This is called the locus and is determined in Meiosis by gametes from parent cells. During meiosis there is this thing called 'crossing over' where the gametes (sperm and egg cells) homologous genes (genes of similar size and shape, such as X and Y chromosomes or X and X) exchange genes on the same locus to provide slightly different characteristics.

Please check this with your teacher but i believe that this is right. Hope this helps. ;)

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.

the titanic would be the correct answer
