The root of an onion is a rapidly growing part of an onion

The root of an onion is a rapidly growing part of an onion. Many cells will be in different stages of mitosis. A sample of an onion tip was stained and studied under a microscope. Various phases of mitosis were identified in the table below.

1.1 Diabetes insipidus (dilute urine) is a disease caused by a lack of ADH secretion into plasma. Scientists wanted to determine the effect of this disease on the volume of urine that a person produces per day. The investigation was carried out on 5 male participants over a period of 30 days. The males were of similar age
and weight. Their average daily urine production was calculated and recorded in the table below.
NOTE: Normal daily urine production is between 600 mf — 1800 mt
