Answer:
in male lion, two methyl groups are present in its structure while in female lion, two hydroxl groups are present in its structure

The chemical structure of the carbon atom is different in both male and female lion because both male and female lions have different sex harmones which are totally different from one another. In male lion, testosterone is a sex hormone whose chemical formula is C19H28O2 and two methyl groups and one hydroxl group are present in its structure while in female lion, oestradiol is a sex hormone having a chemical formula C18H24O2 and two hydroxyl groups are present.
