Step-by-step explanation:
As rightly said in this question, the kidney is the major excretory organ in our (human) system, which also helps maintain homeostatic balance between water and waste products. According to the question, the kidneys function to filter blood of waste products and control how much water is kept in the body.
Since urine is a mixture of the removed waste and water, a concentrated urine with a dark yellow color than normal indicates that the involved individual is DEHYDRATED i.e. low in water content of the body and hence needs water.
The urine of this dehydrated individual is this DARK YELLOWISH COLOUR because the kidney RETAINS THE SMALL AMOUNT OF WATER PRESENT IN THAT INDIVIDUALS BODY which ought to make the person's urine diluted, hence, the urine contains more of waste products (urea) and less of water, making it appear darker yellow than that of a healthy individual.
