It is caused by diarrhoea( watery stools )

2.Excessive sweating.

3 vomiting continusly.

4. No access to water intake

5.Polyuria(excessive urination)

6.Fever leading to hyperthermia.

The kidney is the main organ where the effect of dehydration is managed . As a result of increase in the solute potential of the blood,;the hypothalamus secrets ADH hormones which stimulates the Aquaporins(transmembrane proteins in the collecting duct and the distal convoluted tubules) to open .Therefore water moves in by osmosis to reduce the higher solute potential of the blood. Therfore low volume,high concentrated urine is produced.

This homeostatic function of the kidney ensures balanced in the electrolyte fluids of the body to manage dehydration,before medical intervention.

Explanation:

Correct A). Predicting weather patterns

The scientific modeling is a way, which tries to make a specific phenomenon of the world easier to define, understand, simulate, quantify, visualize it according to the existing and commonly accepted knowledge.

Example of scientific models includes a model of predicting eclipses, model that explain weather phenomena etc.

Hence, the correct answer would be option A.
