Question

would living things most likely be affected if there were a shortage of water on earth? living things would not be able to live, reproduce, or regulate their own temperature. living things would not be able to absorb and transport heat or regulate their own temperature. living things would not be able to reproduce or absorb and transport heat. living things would not be able to regulate their own temperature, live, or absorb or transport heat.

Explanation:

Water is essential for all core life functions: it is required for cellular processes that sustain life, is involved in reproductive mechanisms in most organisms, and acts as a key agent for thermoregulation (like sweating in animals, transpiration in plants). The first option encompasses all these critical, non-negotiable impacts of a global water shortage on living things, while the other options omit at least one vital function.

Answer:

Living things would not be able to live, reproduce, or regulate their own temperature.
