Final answer:
Water is essential for our survival because it makes up a large portion of our bodies, is involved in chemical reactions, and helps maintain homeostasis.
Step-by-step explanation:
Water is essential for our survival for several reasons:
- Water makes up a large portion of our bodies, accounting for 60-70% of our body weight. It is necessary for maintaining bodily functions such as digestion, circulation, and temperature regulation.
- Water is involved in many chemical reactions that occur in our bodies. For example, it acts as a solvent, transporting nutrients and waste products throughout our cells.
- Water is also crucial for maintaining homeostasis. It helps to balance the pH level and temperature in our bodies, ensuring that our cells can function properly.
Without water, our bodies cannot function optimally, and our health and survival would be compromised.
