Can you put the question here?
In humeral fractures, the main nerves in the arm may have been damaged or compressed (by the cast) after manual reduction. The sensory nerve involved in this case is the musculocutaneous nerve which provide sensation in the hands, particularly here in the right hand. Compression by the cast interrupts nerve impulses in the musculocutaneous nerve owing to the loss of sensation and the removal of cast relieves the compression therefore there is regain of sensation.
2 cells will be produced each one containing 2 chromosomes.
<h3><u>Explanation:</u></h3>
The meiosis is the reduction division in the cells undergoing to produce gametes, where the homologous chromosome pairs separate to produce new cells. In the parent cell, there are homologous pairs of chromosomes, so the cell is diploid, but in the daughter cells, the cells are having one of the chromosomes of each type, so are haploid.
In the diagram, there are four chromosomes, i.e 2 homologous chromosome pairs. So after meiosis, there will be 2 chromosomes - one black and one white as depicted from the picture.
