The pairs of chromosomes become arranged on the metaphase plate.
Please mark brainliest and have a great day!
This stage is characterised by the arrangement of homologous chromosomes at the equator of the cell and the formation of micro tubules(spindle and fibres) attached to the centomere of each homologous chromsomes.
i hope that this helps
Of these choices, the only one which does not occur in metaphase I is sister chromatids are separated and pulled to opposite poles. This actually occurs during anaphase II.
The answer is actually B
Yes, the random alignment of the tetrads along with the equatorial plate occurs during metaphase I.
After the crossing-over in prophase I, and during metaphase I, fibers of the spindle apparatus capture chromosomes and take them toward the center of the cell, to the metaphase plate. The homologous pairs of chromosomes get aligned in the metaphase plate for their posterior separation in anaphase I.
Each chromosome of the pair joins with a microtubule of only one of the spindle poles, so the two equivalent chromosomes join the fibers of opposites poles.
When they align in the center of the cell, their orientation is random.
the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
