Answer:
(a) The hormone that will be deficient in the case of the human pancreas not functioning properly is insulin. Insulin is produced by the beta cells of the pancreas and helps regulate blood sugar levels by facilitating the uptake of glucose from the blood into cells.
(b) The disease that the human is likely to suffer from in this case is diabetes. There are two main types of diabetes: type 1 diabetes, which occurs when the body's immune system attacks and destroys the beta cells in the pancreas that produce insulin, and type 2 diabetes, which occurs when the body becomes resistant to the effects of insulin or does not produce enough insulin to meet the body's needs.
(c) Diuresis is the increased production of urine by the kidneys. It can be caused by a variety of factors, including increased fluid intake, medications, certain medical conditions such as diabetes insipidus or kidney disease, and hormonal imbalances. Diuresis can be a normal response to increased fluid intake or it can be a symptom of an underlying medical condition.
