Which of the following accurately describes carbon atoms?
a. carbon atoms can only form triple bonds with other carbon atoms.
b. carbon atoms only have three electrons available for bonding.
c. carbon atoms are only found in two of the four main macromolecules.
d. carbon atoms can bond to other carbon atoms.

The best answer is D.

Carbon  has an affinity for bonding with other small atoms including other carbon atoms, via the formation of stable covalent  bonds.

In spite of the fact that carbon is present in a vast number of compounds, carbon is weakly reactive  compared to other elements.

It has the ability to form very long chains of strong and stable interconnecting  C-C bonds. This property allows carbon to form an almost infinite number of compounds. There are more known carbon-containing compounds than all the compounds of the other chemical elements  combined except those of hydrogen because almost all organic compounds contain hydrogen as well.

for 8 am not sure maybe yes?

for 9 if it is asking if the male is more or less it would be less

hope i even just a little : )
