Meiosis in reproductive organs (testes and ovary) produce gametes. Each human cell including reproductive cells contains 23 pair of chromosomes. Meiosis separates the two chromosomes from each pair thus, each gamete receives only one copy of each chromosome. Therefore, each gamete has 23 new chromosomes, one from each of the 23 pairs. During meiosis, exchange of chromosome segment between copies of a pair of chromosomes. The exchange of chromosome segments creates new combinations of genes which enhances genetic variability within a species.

B - Many Agricultural practices bear some pretty bad impacts on the environment. A, C and D are incorrect.
The environmental parameters that should be monitored to ensure that the plant is not adversely affecting the animal species near the plant are MIGRATING BIRD POPULATION AND THE CARRY CAPACITIES OF THE LOCAL ANIMAL SPECIES. Monitoring these parameters, we allows the city to know if the plant set up is affecting the population of the animals in the area.
