A disease causing bones to become porous and brittle
Nervous system disorder affecting movement
Colorless, odorless gas necessary for life
Loss of ability to move

The correct answer is: Colorless, odorless gas necessary for life

Oxygen is defined as a colorless, odorless gas that is essential for life. It is a critical component of the air we breathe and plays a vital role in the process of cellular respiration, where it is used by cells to convert glucose into energy. This process is fundamental for the survival of most living organisms, as it enables the production of energy necessary for various bodily functions. Understanding the role of oxygen in sustaining life is crucial in healthcare settings, as many medical conditions can arise from low oxygen levels, leading to interventions such as supplemental oxygen therapy. The other options describe various health conditions or disorders but do not pertain to the nature of oxygen itself, highlighting the importance of recognizing oxygen’s basic properties and significance in health and medicine.
