<span>Natural nitrogen fixation; An important part of the natural nitrogen cycle were nitrogen gas (N2) in the atmosphere is converted into ammonia (NH3) in in the ground.  Some bacteria (diazotrophs), both free living in the soil and in symbiosis with root nodules of some plants, use enzymes (nitrogenazes) to convert the nitrogen into a form that can be used by living organisms.Hope this helps :/

parts of 4500. then

x+y=4500 __ (1)

given

5% of x = 10% of y

100

5x

=

100

10y

x=2y

2y+y=4500

3y=4500

y=1500

x+1500=4500

x=4500−1500

x=3000

hence the 4500 is been divided into

two parts of 1500 and 3000.

Q3.13. approximately how long did it take for the recessive allele to decline to half its initial frequency?
yaroslaw [1]

The rate for a recessive allele to decline to half its initial frequency will depend on the presence of selective evolutionary forces and random mating.

<h3>What is recessive allele frequency?</h3>

The recessive allele frequency refers to the initial frequency of a recessive allele in a population, which is masked in heterozygous individuals.

The recessive allele frequency depends on the adaptive fitness of this gene variant, the presence of selective forces and random mating, that facet its rate of change.

In conclusion, the rate for a recessive allele to decline to half its initial frequency will depend on the presence of selective evolutionary forces and random mating.
