<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 :/

True, the justice in school would be sending a bully or someone who did something bad to the principals office, getting a referral, suspended, or expelled, the fairness is that if you saw the fight, and did t join it, you dont get any punishment since you did t take part in it.

A plant breeder has determined the following variances for yield of corn in his fields:
Law Incorporation [45]

Answer:

A. VG = 80

B. Broad sense heritability = 0.80

C. Narrow sense heritability = 0.30

D. Average yield = 430 Units

Explanation:

A. Given that

VA = 30

VD = 50

VI = assumed not available

Therefore

Total genetic variance (VG) = VA + VD

= 30 + 50

= 80

VG = 80

B. Given that

VP = 100

VG = 80

Broad sense heritability, H2 = VG/VP

= 80/100

= 0.80

C. Given that

VA = 30

VP = 100

Narrow sense heritability, h2 = VA/VP

=30/100

= 0.30

D. The difference in selection = 500 - 400

= 100

Recall,

Selection response is heritability multiplied by selection differential.

That is

R = h2S

Selection differential = 100

Heritability h2 = 0.30

Selection response = 0.30 × 100

= 30units

Therefore, expected average yield = 400 + 30

= 430 Units
