The difference is that Carbohydrates are used for energy (glucose). Fats are used for energy after they are broken into fatty acids. Protein can also be used for energy, but the first job is to help with making hormones, muscle, and other proteins. Broken down into glucose, used to supply energy to cells.
<span>Since the polonium atom has 84 electrons, it also has 84 protons. The protons have a positive charge (+1), and are in the nuclueus with the neutrons (no charge). The electrons (charge =-1) are NOT in the nucleus, but surround it. Thus, the total charge of the polonium nucleus is +84</span>
<h2>Answer:</h2>
To differentiate between the structural properties of the chemical molecules.
<h3>Explanation:</h3>
Isomers of a chemical compound are two chemical compounds having the same chemical formula but different structure in three dimension.
Many physical and chemical properties are dependent on the structure of the chemical molecules.
These structural differences leads to many different bonding abilities to other molecules and leads to different properties like melting and boiling points.

Vestigial traits are adaptations to environmental pressures which are no longer present.
