**Title: Exploring the Role of the Carbon Atom in Biological Differences: A Case Study of Male and Female Lions**This educational module aims to delve into the fascinating world of biology by examining how the chemical structure of carbon atoms contributes to the observable differences between male and female lions. **Introduction:**The carbon atom is fundamental in the chemistry of life. By examining its role, we can understand the underlying mechanisms that lead to the various physical and functional differences between genders in the animal kingdom.**Observation:**In the provided photograph, we observe a male lion and a female lion. - **Male Lion:** Characterized by a large mane surrounding its face, giving it a more imposing stature.- **Female Lion:** Smaller in comparison, with a lack of a mane, which makes them appear less robust than their male counterparts.**Question:***How does the chemical structure of the carbon atom account for the differences between the male and female lions seen in the photo?***Activity:**Match the terms in the left column to the appropriate blanks in the sentences on the right. Not all terms will be used.---This module integrates visual and interactive learning to highlight the significance of carbon in biological diversity, specifically in gender differences among lions. Through this exercise, students will gain a deeper understanding of the biochemical underpinnings that manifest as distinct physical traits. ### The Versatility of Carbon in Organic MoleculesBecause carbon has a valence of **4**, it can form **four covalent** bonds with other atoms. Such versatility of carbon allows for building the skeletons of organic molecules, including important biomolecules.#### Steroids as an ExampleFor example, carbon skeletons in the shape of four fused rings make up **steroids**, some of which are sex hormones. Estradiol, a **female** sex hormone, and testosterone, a **male** sex hormone, are very similar in structure, differing only in **two** **chemical groups**. It leads to different **shapes and chemical characteristics**, allowing them to bind to molecules on the surface of different target cells and result in different **effects**, such as the differences between the lions in the photo.

In many cases observe in nature, the basis of the morphological differences observed between the…
