because there are 12 hydrogen atoms and 6 carbon atoms. hope this helps!
I believe the answer is B (C). Mitosis is the process of cell division that takes place in the somatic cells where a parent cells divides in two diploid daughter cells. Prometaphase is the second phase of mitosis, the process separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During this stage, the physical barrier that enclose the nucleus (the nuclear envelop ) breaks.

Thick myosin filaments of muscle are associated with the characteristics of contractility.
Explanation:
The muscle contractility is provided mainly the thick and the thin muscle filaments. Thick muscle filaments are constituted by the contractile protein, myosin. Thin filament is composed of actin.
Owing to its thickness, myosin protein is made up of six chains of polypeptides with four lighter (molecular mass is low) ones and two heavier (molecular mass is high) ones.
The two heavier polypeptide chains twist together like two twisted golf clubs and forms a coiled-rod like structure. This coiled structure looks like a two stranded double helix.
The globular heads point out from the main body in each coiled structure and adheres with the head of the actin filaments. The tails made up of lighter chains point towards the M lines of the sarcomere.
During muscle contraction, the myosin head will attach with its myosin-binding site.
