Looking through a light microscope at a cell undergoing division, you see that the condensed chromosomes have lined up along the midline of the cell. the homologous pairs are not joined in tetrads. each chromosome takes its own place in line, independent of its homolog. you are witnessing

Mitotic metaphase or metaphase II of meiosis

Explanation:

Metaphase in mitosis and metaphase II of meiosis II include alignment of chromosomes along the equator of the cell with help of spindle apparatus. Here, each chromosome has two sister chromatids.

Metaphase I of meiosis I includes alignment of homologous pairs along the equator of the cell. Since the observed cell have individuals chromosomes aligned along the mid line of the cell, it is metaphase of mitosis or metaphase II of meiosis.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
