<h3>Covalent bonding </h3>
Covalent bonding is the sharing of electrons between two atoms. This type of bonding occurs between two or more nonmetals.
Elements formed by covalent bonds are non-metal elements and the atoms that form covalent bonds are non-metal atoms. the scientific names of two atoms that are covalently bonded are ; hydrogen and oxygen to form water
H₂ + O = H₂O
Hence we can conclude that The scientific names for two atoms covalently bonded are : Hydrogen and oxygen.

C. How the organism is related to others
Explanation:
From a single fossil, a scientist can learn how the organism is related to others. Fossils are the preserved remains of organisms that are usually found in rocks.
- Organisms must posses certain characteristics to ensure their preservation as fossils.
- Most organisms that are preserved usually have hard parts.
- Some climatic influence can also arrest decay and provide a platform organisms to be preserved wholly.
- Fossils are used for relative dating of events in nature.
- They can also be used to determine how an organism is related to another.
- This is called phylogeny. It is the study of evolution and how organisms relates to one another.
- Fossils are very good and useful phylogenetic tools.
