To counter the argument: “It is ignorant to worry about industry or agriculture contaminating the environment with their chemical wastes. After all, this stuff is just made of the same atoms that were already present in our environment.”
Concept introduction: The chemical reactivity of an element is determined by the presence of unpaired electrons in the outermost shell (or valence cell) and the electrons present in it are called valence electrons. An atom can be chemically inert if they have fulfilled the outermost valence shell. The emergent properties are owing to the arrangement and contacts of atoms or groups of atoms. The properties of compounds are different from the individual elements from which it has formed. A compound is formed by the interaction of two or more dissimilar elements in a definite ratio.

- Biomolecules: What are the building blocks of life? From the smallest single-celled organism to the tallest tree, all life depends on the properties and reactions of four classes of organic (carbon-based) compounds-carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates, Lipids, and Proteins are the 3 building blocks of all living things that we will focus on in this unit. These are called macromolecules (or biomolecules) because they are large molecules. They are responsible for most of the body's structure and functions, including energy storage, insulation, growth, repair, and communication. Simple organic molecules can be joined together to form all the essential biological molecules needed for life. Table 1 shows a sample elephant diet and Table 2 shows a sample lion diet. Using the background information, predict the main function of the macromolecules in their diet.
