How many base pairs would a dna segment of length 1.36mm have?

4.0 million

Explanation:

The average length of a base pair (bp) is 340 pm (340 × 10^-12 m)

Length of DNA = Number of bp × length of each bp

 1.36 × 10^-3 m = bp × 340 × 10^-12 m

                    bp = (1.36 × 10^ -3)/(340 × 10^-12)  = 4.0 × 10^6

The DNA segment would contain 4.0 million bp.

explanation:

b,bacteria convert nitrates

into nitrogen gas.

d,plants and animals take in

and use nitrogen compounds.

e,bacteria break down waste    

products and return nitrogen  

to the soil.

a,bacteria convert atmospheric

nitrogen to ammonia.

c,bacteria convert ammonia

to nitrites and nitrates.

they deliver oxygen to the blood
