In chemistry, there is a class of compounds called alkanes. They have the general formula [tex]$C _x H _{2 x+2}$[/tex], where C stands for a carbon atom and [tex]$H$[/tex] stand's for a hydrogen atom. The subscript [tex]$x$[/tex] stand's for the number of carbon atoms, and the subscript [tex]$2 x+2$[/tex] stands for the number of hydrogen atoms in one molecule of the compound.
\begin{tabular}{|c|c|c|}
\hline Carbon atoms & Hydrogen atoms & Alkane Formula \\
\hline 1 & 4 & [tex]$CH _4$[/tex] \\
\hline 2 & 6 & [tex]$C _2 H _6$[/tex] \\
\hline 3 & 8 & [tex]$C _3 H _8$[/tex] \\
\hline & & \\
\hline
\end{tabular}
Suppose an alkane had 8 carbon atoms. How many hydrogen atoms would it have?
A. 18 atoms
B. 16 atoms
C. 10 atoms
D. 12 atoms

This is true! Prokaryotes are split into two classifications, bacteria and archea. Both of these are prokaryotes because they have no separation in their components, like DNA, organelles, and proteins.
True, they have circular DNA, whereas humans have linear DNA.
Yes, it is true that most prokaryotes contain a single, circular DNA molecule. Prokaryotes like bacteria and archaea have their DNA organized in this way in a region of the cell called the nucleoid. Additionally, they may carry plasmids, which are smaller circles of DNA that can contain beneficial genes.
