Hello! Can anyone explain more about the difference between gender and sex?

You are welcome.

Thank you for the clarification.

Let me try. Sex is used to refer to the biological differences between females and males, whereas gender is used to refer to the sociological differences, such as thoughts, beliefs, and attitudes about women and men. Gender is socially constructed and therefore varies from culture and across time. Additionally, gender roles are assigned to and seen as appropriate for women and men created and reinforced by the dominant culture and society.
