Add the appropriate number of hydrogen atoms to this organic molecule and also remember each carbon must have 4 bonds c-c-c-c

Explanation:

The four covalent bonding positions of the carbon atom can give rise to a wide diversity of compounds with many functions, accounting for the importance of carbon in living things. Carbon contains four electrons in its outer shell. Therefore, it can form four covalent bonds with other atoms or molecules.

a- multicellular

b-eukaryotic

c-no cell wall

d-heterotrophic

e-autotrophic
