The term that describes biological and physiological differences between racial groups is "biological variations." This concept recognizes that populations can exhibit distinct biological traits due to a variety of factors, including genetic differences and evolutionary adaptations shaped by geographical and environmental influences.

Biological variations encompass a range of characteristics such as skin color, body structure, and susceptibility to certain diseases, which can be influenced by inherited genetic traits that vary across different racial and ethnic groups. Understanding these variations is crucial in public health for developing tailored health interventions and recognizing how different populations might respond to diseases or treatments.

The other options do not pertain to the concept of biological differences. "Space" refers to the physical area we occupy and is not relevant in describing physiological characteristics. "Social organization" pertains to the structure of a society and how its members interact, which does not relate to biology. "Time perception" deals with how individuals or groups perceive time, an entirely different psychological and cultural topic, not linked to biological or physiological differences.
