Answer:
The correct answer will be option-C
Explanation:
The rhythm of the heartbeat is controlled by the pacemaker of the heart called the sino-atrial node.
The SA node generates action potentials which trigger the contraction and relaxation of the atrium and ventricles. The membrane potential generation initiates by the depolarization of the cell membrane when the L type of Ca⁺² ions opens up and calcium ions enter the cell.
This depolarizes the cell until the potential threshold is reached which lies between the -40 and -30 mV.
Thus, Option-C is the correct answer.

C. 200 billion
Explanation:
The milky way galaxy is estimated that there is 200 billion stars
You are familiar with the electron transport system in photosynthesis
that takes light energy and converts it to chemical bond energy in the
form of ATP and NADPH. This electron transport chain in cellular
respiration will take the energy stored in NADH and FADH2
during the Krebs cycle and convert it to chemical bond energy in the
form of ATP. In eukaryotes, this reaction takes place on the inner
mitochondrial membrane, as is shown in Figure 4.26. Prokaryotes that
undergo aerobic respiration also have an electron transport chain
located within their plasma membrane, which may be highly folded similar
to the inner membrane of the mitochondrion. Thats the answer my friend hope it helps
