<span>FIXATION.In the nitrogen cycle, nitrogen is converted into many chemical forms through biological and physical processes like nitrogen fixation, ammonification, nitrification and denitrification.During ammonification, ammonium ions are released after decomposition of plants.During nitrogen fixation, nitrogen gas is changed to nitrates by nitrogen fixing bacteria in the soil.These are used by vegetation.</span>

(The punnett square is wrong because both parents are hybrid)
Answer:
more genetic variation within a population usually enables more phenotypic variation.
Explanation:
Because natural selection acts directly only on phenotypes, Some new alleles increase an organism's ability to survive and reproduce, which then ensures the survival of the allele in the population.
Answer:
h = 0.346 m
Explanation:
mercury barometer:
∴ Pa = 0.455 atm = 46102.875 Pa = 46102.875 Kg/ms²
∴ ρ = 13600 Kg/m³
∴ g = 9.80 m/s²
⇒ h = (46102.875 Kg/ms²) / (13600 Kg/m³ )(9.80 m/s²)
⇒ h = 0.346 m
