Answer:
A carbon atom can form up to four covalent bonds as one carbon atom has four valence electrons (in outermost shell). It is a fact that the number of valence electrons in a atom determines the number of covalent bonds it will form. Thus, each electron in carbon atom is used to form four covalent bonds with various four atoms.
Explanation:
A bond between a carbon and hydrogen atom is a non-polar covalent bond. The non-polar covalent bond are the bonds between two atoms which share equal number of electron(s) with each other. Example: as in case of methane, where one carbon atom shares its 4 outer valence electrons with four hydrogens by sharing equal number of electron.
In contrast, polar covalant bond are the bonds between two atoms which share unequal number of electron(s) with each other. Thus these bonds are partially ionic.

Answer:
<h2>Have a common understanding in the classification of organisms</h2>
Explanation:
- Taxonomy plays an important role in the classification of organisms to study the organisms on the basis of their properties.
- Taxonomy is a branch of biological science that explains the identification, characterization, naming and classification of the organisms thus it is helpful to understand the different types of organisms that are present in the biosphere.
- Taxonomy makes the scientist come on one point about the unknown organisms according to morphology, anatomy, physiology and some other properties of the organisms.
- Thus a common understanding is generated among scientists of the world.
