Answer: While Biology is the study of living things, living things themselves are made up of chemical composition. That being said, our survival is dependent on the reactions taking place inside and outside the body. Hence, to understand living things, biologists needs a good understanding of chemistry.
Answer:
variations
Explanation:
if there are variations of something, then there will be different occurrences in the same species. Hope that this helps you and have a great day :)
Answer:
The atoms of each element have a characteristic number of electrons arranged in electron shells. The number of valence electrons determines what types of bonds or ions the atoms may form, so the chemical reactivity of an atom arises from its electron distribution. The properties of compounds emerge from the arrangement of their constituent atoms and of the bonds between them.
Thus, a wide variety of molecules with very different chemical properties can be made from the same basic atoms. Each molecule has a distinctive size, shape, and charge distribution, which determine its highly specific ability to interact with other molecules.
Compounds in chemical wastes may contaminate the environment if their atoms are combined in new arrangements that harm living organisms.
