Final answer:
The daily water consumption for a horse is generally between 10-15 gallons, which aligns with option b). For a human, increased urine output usually begins around 30 minutes after consuming a large glass of water.
Step-by-step explanation:
The average daily water consumption for a horse can typically range from 5 to 15 gallons. This consumption depends on various factors such as the horse's activity level, environmental temperature, and the horse's diet. The correct answer to the question regarding the daily consumption of water in a horse's diet is between 10-15 gallons, hence option b) 10-15 is the right choice.
As for humans, a large glass of water will generally result in increased urine output within about 30 minutes after drinking. This is a part of the body's natural process of osmoregulation, which helps in maintaining homeostasis by balancing the intake and output of water and solutes.
