Final answer:
The terms 'sex' and 'gender' refer to different concepts where 'sex' is a biological distinction between males and females and 'gender' is the cultural expectations and behaviors associated with one's sex. The correct answer to the question is A) Sex; Gender.
Step-by-step explanation:
The distinction between the terms “sex” and “gender” is crucial in understanding human biology and sociology. Sex refers to the observable physical differences between male and female, which are biological and physiological in nature, such as chromosomal differences (XX for females, XY for males) and secondary sex characteristics (e.g., breasts, facial hair). On the other hand, gender refers to the cultural expectations of behavior based on these biological differences. This encompasses behaviors, relationships, responsibilities, and rights attributed to individuals within society, which are learned and subjected to cultural variability and change over time.
In summary, the correct answer to the student's question is A) Sex; Gender. 'Sex' denotes biological aspects determining maleness and femaleness, whereas 'Gender' pertains to the societal and cultural roles and expectations derived from one's sex.
